Preferred Device
SWITCHMODETM Schottky Power Rectifier
The SWITCHMODE Power Rectifier employs the Schottky Barrier principle in a large area metal- to- silicon power diode. State-of-the-art geometry features epitaxial construction with oxide passivation and metal overlay contact. Ideally suited for use as rectifiers in very low-voltage, high-frequency switching power supplies, free wheeling diodes and polarity protection diodes.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. 1. The heat generated must be less than the thermal conductivity from Junction-to-Ambient: dPD/dTJ < 1/RqJA. 2. Proper strike and creepage distance must be provided. 3. Pulse Test: Pulse Width = 300 ms, Duty Cycle 2.0%.
