Notes on ratings and characteristics.
1. Maximum Ratings.
1.1 Off-state voltage ratings.
Unless otherwise indicated, all off-state voltage ratings are given for gate conditions as diagram 1. For
other gate conditions see the curves of figure 5. It should be noted that VDRM is the repeatable peak
voltage which may be applied to the device and does not relate to a DC operating condition. While not
given in the ratings, VDC should ideally be limited to 55% VDRM in this product.
Diagram 1.
1.2 Reverse voltage rating.
All devices in this series have a minimum VRRM of 18 Volts.
1.3 Peak turn-off current.
The figure given in maximum ratings is the highest value for normal operation of the device under
conditions given in note 2 of ratings. For other combinations of ITGQ, VD and Cs see the curves in figures
15 & 16. The curves are effective over the normal operating range of the device and assume a snubber
circuit equivalent to that given in diagram 2. If a more complex snubber, such as an Underland circuit, is
employed then the equivalent CS should be used and Ls<0.3µH must be ensured for the curves to be
applied.

1.4 R.M.S and average current.
Measured as for standard thyristor conditions, double side cooled, single phase, 50Hz, 180° halfsinewave. These are included as a guide to compare the alternative types of GTO thyristors available,
values can not be applied to practical applications, as they do not include switching losses.
2
1.5 Surge rating and I t.
Ratings are for half-sinewave, peak value against duration is given in the curve of figure 2.
1.6 Snubber loop inductance.
Use of GTO thyristors with snubber loop inductance, Ls<0.3µH implies no dangerous Vs voltages (see
diagrams 2 & 3) can be applied, provided the other conditions given in note 1.3 are enforced. Alternatively
Vs should be limited to 800 Volts to avoid possible device failure.

1.7 Critical rate of rise of on-state current
The value given is the maximum repetitive rating, but does not imply any specific operating condition. The
high turn-on losses associated with limit di/dt would not allow for practical duty cycle at this maximum
condition. For special pulse applications, such as crowbars and pulse power supplies, a much higher di/dt
is possible. Where the device is required to operate with infrequent high current pulses, with natural
commutation (i.e. not gate turn-off), then di/dt>5kA/µs is possible. For this type of operation individual
specific evaluation is required.
1.8 Gate ratings
The absolute conditions above which the gate may be damaged. It is permitted to allow VGK(AV) during turnoff to exceed VRGM which is the implied DC condition.
1.9 Minimum permissible off time.
This time relates specifically to re-firing of device (see also note on gate-off time 2.7). The value given in
the ratings applies only to operating conditions of ratings note 2.
1.10 Minimum permissible on-time.
Figure is given for minimum time to allow complete conduction of all the GTO thyristor islands. Where a
simple snubber, of the form given in diagram 1. (or any other non-energy recovery type which discharges
through the GTO at turn-on) the actual minimum on-time will usually be fixed by the snubber circuit time
constant, which must be allowed to fully discharge before the GTO thyristor is turned off. If the anode
circuit has di/dt<10A/µs then the minimum on-time should be increased, the actual value will depend upon
the di/dt and operating conditions (each case needs to be assessed on an individual basis).

2 Characteristics
2.1 Instantaneous on-state voltage
Measured using a 500µs square pulse, see also the curves of figure 1 for other values of ITM.
2.2 Latching and holding current
These are considered to be approximately equal and only the latching current is measured, type test only
as outlined below. The test circuit and wave diagrams are given in diagram 4. The anode current is
monitored on an oscilloscope while VD is increased, until the current is seen to flow during the un-gated
period between the end of IG and the application of reverse gate voltage. Test frequency is 100Hz with IGM
& IG as for td of characteristic data.

2.3 Critical dv/dt
The gate conditions are the same as for 1.1, this characteristic is for off-state only and does not relate to
dv/dt at turn-off. The measurement, type test only, is conducted using the exponential ramp method as
shown in diagram 5. It should be noted that GTO thyristors have a poor static dv/dt capability if the gate is
open circuit or RGK is high impedance. Typical values: - dv/dt<100V/µs for RGK>10Ω.
Diagram 5, Definition of dV/dt.
2.4 Off-state leakage.
For IDRM & IRRM see notes 1.1 & 1.2 for gate leakage IGK, the off-state gate circuit is required to sink this
leakage and still maintain minimum of –2 Volts. See diagram 6.

2.5 Gate trigger characteristics.
These are measured by slowly ramping up the gate current and monitoring the transition of anode current
and voltage (see diagram 7). Maximum and typical data of gate trigger current, for the full junction
temperature range, is given in the curves of figure 6. Only typical figures are given for gate trigger voltage,
however, the curves of figure 3 give the range of gate forward characteristics, for the full allowable
junction temperature range. The curves of figures 3 & 6 should be used in conjunction, when considering
forward gate drive circuit requirement. The gate drive requirements should always be calculated for lowest
junction temperature start-up condition.

2.6 Turn-on characteristics
The basic circuit used for turn-on tests is given in diagram 8. The test is initiated by establishing a
circulating current in Tx, resulting in VD appearing across Cc/Lc. When the test device is fired Cc/Lc
discharges through DUT and commutates Tx off, as pulse from Cc/Lc decays the constant current source
continues to supply a fixed current to DUT. Changing value of Cc & Lc allows adjustment of ITM and di/dt
respectively, VD and i are also adjustable.

In addition to the turn-on time figures given in the characteristics data, the curves of figure 9 give the
relationship of tgt to di/dt and IGM. The data in the curves of figures 7 & 8, gives the turn-on losses both with
and without snubber discharge, a snubber of the form given in diagram 2 is assumed. Only typical losses
are given due to the large number of variables which effect Eon. It is unlikely that all negative aspects
would appear in any one application, so typical figures can be considered as worst case. Where the turnon loss is higher than the figure given it will in most cases be compensated by reduced turn-off losses, as
variations in processing inversely effect many parameters. For a worst case device, which would also
have the lowest turn-off losses, Eon would be 1.5x values given in the curves of figures 7 & 8. Turn-on
losses are measured over the integral period specified below:10 µs
Eon =
∫ iv.dt
0
The turn-on loss can be sub-divided into two component parts, firstly that associated with tgt and secondly
the contribution of the voltage tail. For this series of devices tgt contributes 40% and the voltage tail 60%
(These figures are approximate and are influenced by several second order effects). The loss during tgt is
greatly affected by gate current and as with turn-on time (figure 9), it can be reduced by increasing IGM.
The turn-on loss associated with the voltage tail is not effected by the gate conditions and can only be
reduced by limiting di/dt, where appropriate a turn-on snubber should be used. In applications where the
snubber is discharged through the GTO thyristor at turn-on, selection of discharge resistor will effect Eon.
The curves of figure 8 are given for a snubber as shown in diagram 2, with R=5Ω, this is the lowest
recommended value giving the highest Eon, higher values will reduce Eon.
2.7 Turn-off characteristics
The basic circuit used for the turn-off test is given in diagram 10. Prior to the negative gate pulse being
applied constant current, equivalent to ITGQ, is established in the DUT. The switch Sx is opened just before
DUT is gated off with a reverse gate pulse as specified in the characteristic/data curves. After the period
tgt voltage rises across the DUT, dv/dt being limited by the snubber circuit. Voltage will continue to rise
across DUT until Dc turns-on at a voltage set by the active clamp Cc, the voltage will be held at this value
until energy stored in Lx is depleted, after which it will fall to VDC .The value of Lx is selected to give
required VD Over the full tail time period. The overshoot voltage VDM is derived from Lc and forward voltage
characteristic of DC, typically VDM=1.2VD to 1.5VD depending on test settings. The gate is held reverse
biased through a low impedance circuit until the tail current is fully extinguished.

Diagram 11, Turn-off parameter definitions.
In addition to the turn-off figures given in characteristic data, the curves of figures 10, 11 & 12 give the
relationship of IGQ QGQ and tgq to turn-off current (ITGQ) and diGQ/dt. Only typical values of IGQ are given due
to a great dependence upon the gate circuit impedance, which is a function of gate drive design not the
device. The tgq is also, to a lesser extent, affected by circuit impedance and as such the maximum figures
given in data assume a good low impedance circuit design. The curves of figures 17 & 18 give the tail time
and minimum off time to re-fire device as a function of turn-off current. The minimum off time to re-fire the
device is distinct from tgw, the gate off time given in characteristics. The GTO thyristor may be safely retriggered when a small amount of tail current is still flowing. In contrast, the gate circuit must remain low
impedance until the tail current has fallen to zero or below a level which the higher impedance VGR circuit
can sink without being pulled down below –2 Volts. If the gate circuit is to be switched to a higher
impedance before the tail current has reached zero then the requirements of diagram 12 must be applied.

The figure tgw, as given in the characteristic data, is the maximum time required for the tail current to
decay to zero. The figure is applicable under all normal operating conditions for the device; provided
suitable gate drive is employed. At lower turn-off current, or with special gate drive considerations, this
time may be reduced (each case needs to be considered individually).Typical turn-off losses are given in
the curves of figures 13 & 14, the integration period for the losses is nominally taken to the end of the tail
time (Itail<1A) i.e. :tgt + ttail

The curves of figure 13 give the turn-off energy for a fixed VD with a VDM=120%VD, whereas the curves of
figure 14 give the turn-off energy with a fixed value of VDM and VD=50%VDRM. The curves are for energy
against turn-off current/snubber capacitance with a correction for voltage inset as an additional graph
(snubber equivalent to diagram 2 is assumed). From these curves a typical value of turn-off energy for any
combination of ITGQ/Cs and VD or VDM can be derived. Only typical data is included, to allow for the tradeoff with on-state voltage (VTM) which is a feature of these devices, see diagram 13. When calculating
losses in an application, the use of a maximum VTM and typical Eoff will (under normal operating
frequencies) give a more realistic value. The lowest VTM device of this type would have a maximum turnoff energy of 1.5x the figure given in the curves of figures 13 & 14.

2.8 Safe turn-off periphery
The necessity to control dv/dt at tun-off for the GTO thyristor implies a trade-off between ITGQ/VDM/Cs. This
information is given in the curves of figures 15 & 16. The information in these curves should be
considered as maximum limits and not implied operating conditions, some margin of 'safety' is advised
with the conditions of the curves reserved for occasional excursions. It should be noted that these curves
are derived at maximum junction temperature, however, they may be applied across the full operating
temperature range of the device provided additional precautions are taken. At very low temperature,
(below –10°C) the fall-time of device becomes very rapid and can give rise to very high turn-off voltage
spikes, as such it is advisable to reduce snubber loop inductance to <0.2µH to minimise this effect.
