NOTES: A. Resistor R1 is adjusted for the specified value
of I
RM
.
B. Resistor R2 value is 30/I
H
, where I
H
is the
holding current value of thyristor TH1.
C. Thyristor TH1 is the same device type as the
DUT.
D. Pulse Generators, G1 and G2, are
synchronised to produce an on-state anode
current waveform with the following
characteristics:
t
P
= 50 µs to 300 µs
duty cycle = 1%
E. Pulse Generators, G1 and G2, have output
pulse amplitude, V
G
, of
≥
20 V and duration of
10 µs to 20 µs.
