10/1000 μs (REA PE-60, open-circuit voltage wave shape 10/1000 μs)
Non-repetitive peak on-state current, 50 Hz, 0.7 s (see Notes 1 and 2)
Initial rate of rise of on-state current,
Linear current ramp, Maximum ramp value < 38 A
Junction temperature
Operating free - air temperature range
Storage temperature range
Lead temperature 1.5 mm from case for 10 s
NOTES: 1. Above 70°C, derate linearly to zero at 150°C case temperature
2. This value applies when the initial case temperature is at (or below) 70°C. The surge may be repeated after the device has
returned to thermal equilibrium.
3. Most PTT’s quote an unloaded voltage waveform. In operation the TISP essentially shorts the generator output. The resulting
loaded current waveform is specified.

NOTE
4: These capacitance measurements employ a three terminal capacitance bridge incorporating a guard circuit. The third terminal is
connected to the guard terminal of the bridge.
