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. Data Sheet.

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 (i) Qra is based on 50% Irm chord as shown in Fig. 1 Fig. 1 150 µs (ii) Qrr is based on a 150µs integration time i.e. Qrr = ∫i rr .dt 0 (iii) Data Sheet.

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 Where: Data Sheet.
