INFORMATION

absolute maximum ratings at

25°C case temperature (unless otherwise noted))

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.

.

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.
