6.0 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.

7.0 Square wave ratings
These ratings are given for load component rate of rise of forward current of 100 and 500 A/µs.

8.0 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.

9.0 Maximum Operating Frequency
The maximum operating frequency is set by the on-state duty, the time required for the thyristor to turn off

12.0 Reverse Recovery Loss

12.1 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:

FactorK =

=

where k = 0.227 (°C/W)/s
E = Area under reverse loss waveform per pulse in joules (W.s.)

12.2 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

SINK (original)

A suitable R-C snubber network is connected across the thyristor to restrict the transient reverse voltage

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:

13.0 Gate Drive

The recommended pulse gate drive is 30V, 15Ω with a short-circuit current rise time of not more than

0.5µs. This gate drive must be applied when using the full di/dt capability of the device.

The duration of pulse may need to be configured with respect to the application but should be no shorter
than 20µs, otherwise an increase in pulse current could be needed to supply the resulting increase in
charge to trigger.
