DRAIN Voltage ................................................-0.3 V to 700 V

EN/UV Voltage ................................................... -0.3 V to 9 V

EN/UV Current ........................................................... 100 mA

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

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

Notes:

1. All voltages referenced to SOURCE, T

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 Maximum Rating conditions for

extended periods of time may affect product reliability.
