NOTES: A. Resistor R1 is adjusted for the specified value

of I

B. Resistor R2 value is 30/I

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

duty cycle = 1%

E. Pulse Generators, G1 and G2, have output

pulse amplitude, V

10 µs to 20 µs.
