Introduction
The R0577 series of Distributed Gate Thyristors have fast switching characteristics provided by a
regenerative, interdigitated gate. They also exhibit low switching losses. They are therefore suitable for
medium frequency applications.

Notes on Ratings and Characteristics
1.0 Voltage Grade Table
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 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 500A/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
(tq) and for the off-state voltage to reach full value (tv), i.e.

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:
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.
R
= d.c. thermal resistance (°C/W).
