Notes:-
1) Unless otherwise indicated Tj=125oC.
2) For other clamping forces, consult factory.
3) The gate off-time, is the period during which the gate circuit is required to remain at low impedance to allow for the passage of
tail current.

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.
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
14 & 15. 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.
Ls
Ds R
Cs
Diagram 2.
1.4 R.M.S and average current.
Measured as for standard thyristor conditions, double side cooled, single phase, 50Hz, 180° half-
sinewave. 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.
1.5 Surge rating and I2t.
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 turn-
off 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).
