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.

NOTES: 4. These parameters must be measured using pulse techniques, tw = 100 µs, duty cycle ≤ 2%.
5. These parameters are measured with voltage sensing contacts seperate from the current carrying contacts located within 3.2 mm
(0.125 inch) from the device body.
6. Linear rate of rise, maximum voltage limited to 80 % VZ (minimum).
