LNK362-364

ABSOLUTE MAXIMUM RATINGS(1,5)

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

Peak DRAIN Current: LNK362................200 mA (375 mA)(2)

LNK363/364.........400 mA (750 mA)(2)

FEEDBACK Voltage ...........................................-0.3 V to 9 V

FEEDBACK Current ...................................................100 mA

BYPASS 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, TA = 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 Maximum Rating conditions for

extended periods of time may affect product reliability.
