Notes on ratings and characteristics.
1. Maximum Ratings.
Symmetrical Gate Turn-Off Thyristor type S0700KC17#
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 V
DRM
is the repeatable peak
voltage which may be applied to the device and does not relate to a DC operating condition. While not
given in the ratings, V
DC
should ideally be limited to 60% V
DRM
in this product.
Diagram 1.
1.2 Reverse voltage rating.
All devices in this series have a minimum V
RRM
of 100 Volts. If specified at the time of order, a V
RRM
up to
80%V
DRM
is available.
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 I
TGQ
, V
D
and C
s
see the curves of figures
15 & 16. 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 C
S
should be used and L
s
<0.3µH must be ensured for the curves to be
applied.

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 I t.
Ratings are for half-sinewave, peak value against duration is given in the curve of figure 4.
1.6 Snubber loop inductance.
Use of GTO thyristors with snubber loop inductance, L
s
<0.3µH implies no dangerous V
s
voltages (see
diagrams 2 & 3) can be applied, provided the other conditions given in note 1.3 are enforced. Alternatively
V
s
should be limited to 600 Volts to avoid possible device failure.
