2.0 Extension of Voltage Grades
This report is applicable to other and higher voltage grades when supply has been agreed by
Sales/Production.
3.0 Extension of Turn-off Time
This Report is applicable to other tq/re-applied dv/dt combinations when supply has been agreed by
Sales/Production.
4.0 Repetitive dv/dt
Higher dv/dt selections are available up to 1000V/µs on request.
5.0 De-rating Factor
A blocking voltage de-rating factor of 0.13%/°C is applicable to this device for Tj below 25°C.
6.0 Snubber Components
When selecting snubber components, care must be taken not to use excessively large values of snubber
capacitor or excessively small values of snubber resistor. Such excessive component values may lead to
device damage due to the large resultant values of snubber discharge current. If required, please consult
the factory for assistance.
7.0 Rate of rise of on-state current
The maximum un-primed rate of rise of on-state current must not exceed 1500A/µs at any time during
turn-on on a non-repetitive basis. For repetitive performance, the on-state rate of rise of current must not
exceed 1000A/µs at any time during turn-on. Note that these values of rate of rise of current apply to the
total device current including that from any local snubber network.
8.0 Gate Drive
The nominal requirement for a typical gate drive is illustrated below. An open circuit voltage of at least 30V
is assumed. This gate drive must be applied when using the full di/dt capability of the device.
IGM
4A/µs
IG
tp1
The magnitude of IGM should be between five and ten times IGT, which is shown on page 2. Its duration
(tp1) should be 20µs or sufficient to allow the anode current to reach ten times IL, whichever is greater.
Otherwise, an increase in pulse current could be needed to supply the necessary charge to trigger. The
‘back-porch’ current IG should remain flowing for the same duration as the anode current and have a
magnitude in the order of 1.5 times IGT.

9.0 Frequency Ratings
The curves illustrated in figures 10 to 18 are for guidance only and are superseded by the maximum
ratings shown on page 1.
10.0 Square wave ratings
These ratings are given for load component rate of rise of forward current of 100 and 500 A/µs.
11.0 Duty cycle lines
The 100% duty cycle is represented on all the ratings by a straight line. Other duties can be included as
parallel to the first.
12.0 Maximum Operating Frequency
The maximum operating frequency is set by the on-state duty, the time required for the thyristor to turn off
(tq) and for the off-state voltage to reach full value (tv), i.e.
f
max
=
1
tpulse + tq + tv
13.0 On-State Energy per Pulse Characteristics
These curves enable rapid estimation of device dissipation to be obtained for conditions not covered by
the frequency ratings.
Let Ep be the Energy per pulse for a given current and pulse width, in joules
Let Rth(J-Hs) be the steady-state d.c. thermal resistance (junction to sink)
and TSINK be the heat sink temperature.
Then the average dissipation will be:
W AV = E P ⋅ f and TSINK (max .) = 125 − (W AV ⋅ Rth ( J − Hs ) )
14.0 Reverse recovery ratings

15.0 Reverse Recovery Loss
15.1 Determination by Measurement
From waveforms of recovery current obtained from a high frequency shunt (see Note 1, Page 5) and
reverse voltage present during recovery, an instantaneous reverse recovery loss waveform must be
constructed. Let the area under this waveform be E joules per pulse. A new heat sink temperature can
then be evaluated from the following:
TSINK ( new ) = TSINK ( original ) − E ⋅ (k + f ⋅ Rth ( J − Hs ) )
Where k=0.227 (°C/W)/s
E = Area under reverse loss waveform per pulse in joules (W.s.)
f = rated frequency Hz at the original heat sink temperature.
Rth(J-Hs) = d.c. thermal resistance (°C/W).
The total dissipation is now given by:
W (TOT) = W (original) + E ⋅ f
15.2 Determination without Measurement
In circumstances where it is not possible to measure voltage and current conditions, or for design
purposes, the additional losses E in joules may be estimated as follows.
Let E be the value of energy per reverse cycle in joules (curves in Figure 9).
Let f be the operating frequency in Hz
TSINK ( new ) = TSINK (original ) − (E ⋅ Rth ⋅ f )
Where TSINK (new) is the required maximum heat sink temperature and
TSINK (original) is the heat sink temperature given with the frequency ratings.
A suitable R-C snubber network is connected across the thyristor to restrict the transient reverse voltage
to a peak value (Vrm) of 67% of the maximum grade. If a different grade is being used or Vrm is other than
67% of Grade, the reverse loss may be approximated by a pro rata adjustment of the maximum value
obtained from the curves.
NOTE 1- Reverse Recovery Loss by Measurement
This thyristor has a low reverse recovered charge and peak reverse recovery current. When measuring
the charge, care must be taken to ensure that:
(a) a.c. coupled devices such as current transformers are not affected by prior passage of high
amplitude forward current.
(b) A suitable, polarised, clipping circuit must be connected to the input of the measuring oscilloscope
to avoid overloading the internal amplifiers by the relatively high amplitude forward current signal
(c) Measurement of reverse recovery waveform should be carried out with an appropriate critically
damped snubber, connected across diode anode to cathode. The formula used for the calculation
of this snubber is shown below:
R2 = 4 ⋅
Vr
CS ⋅ di dt

16.0 Computer Modelling Parameters
16.1 Calculating VT using ABCD Coefficients
The on-state characteristic IT vs VT, on page 7 is represented in two ways;
(i)
the well established V0 and rs tangent used for rating purposes and
(ii)
a set of constants A, B, C, D, forming the coefficients of the representative equation for VT in
terms of IT given below:
VT = A + B ⋅ ln (I T ) + C ⋅ I T + D ⋅ I T
The constants, derived by curve fitting software, are given in this report for hot and cold characteristics
where possible. The resulting values for VT agree with the true device characteristic over a current range,
which is limited to that plotted.
