LNK362-364
ABSOLUTE MAXIMUM RATINGS(1,5)
DRAIN Voltage ...............................................-0.3 V to 700 V Notes:
Peak DRAIN Current: LNK362................200 mA (375 mA)(2) 1. All voltages referenced to SOURCE, TA = 25 °C.
LNK363/364.........400 mA (750 mA)(2) 2. The higher peak DRAIN current is allowed while the
FEEDBACK Voltage ...........................................-0.3 V to 9 V
DRAIN voltage is simultaneously less than 400 V.
FEEDBACK Current ...................................................100 mA 3. Normally limited by internal circuitry.
BYPASS Voltage..................................................-0.3 V to 9 V 4. 1/16 in. from case for 5 seconds.
Storage Temperature .....................................-65 °C to 150 °C 5. Maximum ratings specified may be applied, one at a time,
Operating Junction Temperature(3) ................-40 °C to 150 °C
Lead Temperature(4) ....................................................... 260 °C
without causing permanent damage to the product.
Exposure to Absolute Maximum Rating conditions for
extended periods of time may affect product reliability.
