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

DRAIN Peak Current:

Feedback Voltage ................................................. ....... -0.3 V to 9 V

Feedback Current ............................................................... 100 mA

BYPASS Pin Voltage ..................................... ............. -0.3 V to 9 V

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

Operating Junction Temperature.........................-40 °C to 150 °C

Notes:

1. All voltages referenced to SOURCE, T

2. Duration not to exceed 2 msec.

3. 1/16 in. from case for 5 seconds.

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

voltage is simultaneously less than 400 V.

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

without causing permanent damage to the product.

Exposure to Absolute Maximum ratings for extended

periods of time may affect product reliability.
