BP/M Voltage .................................................. ...... -0.3 V to 9 V

Storage Temperature ...................................... -65 °C to 150 °C

Operating Junction Temperature(3)................... -40 °C to 150 °C

Lead Temperature(4) ........................................................260 °C

Notes:

1. All voltages referenced to SOURCE, T

A = 25 °C.

2. The higher peak DRAIN current is allowed while the DRAIN

voltage is simultaneously less than 400 V.

3. Normally limited by internal circuitry.

4. 1/16 in. from case for 5 seconds.

5. Maximum ratings specified may be applied one at a time,

without causing permanent damage to the product. Exposure

to Absolute Rating conditions for extended periods of time

may affect product reliability.
