LNK302/304-306

ABSOLUTE MAXIMUM RATINGS^(1,5)

DRAIN Voltage ..................................................-0.3Vto700V Notes:

PeakDRAINCurrent(LNK302).................200mA(375 mA)⁽²⁾1. All voltages referenced to SOURCE, T_A= 25 °C.

PeakDRAINCurrent(LNK304).................400mA(750 mA)⁽²⁾2. The higher peak DRAIN current is allowed if the DRAIN

PeakDRAINCurrent(LNK305).................800mA(1500 mA)⁽²⁾

to SOURCE voltage does not exceed 400 V.

PeakDRAINCurrent(LNK306).................1400mA(2600 mA)⁽²⁾3. Normally limited by internal circuitry.

FEEDBACK Voltage .........................................-0.3 V to 9 V 4. 1/16 in. from case for 5 seconds.

FEEDBACK Current.............................................100 mA 5. Maximum ratings speciﬁed may be applied, one at a time,

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

StorageTemperature..........................................-65°C to150°C

OperatingJunctionTemperature⁽³⁾.....................-40°C to150°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.
