Schottky Power Rectifier

Surface Mount Power Package

This series of Power Rectifiers employs the Schottky Barrier

principle in a large metal−to−silicon power diode. State−of−the−art

geometry features epitaxial construction with oxide passivation and

metal overlay contact. Ideally suited for use in low voltage, high

frequency switching power supplies, free wheeling diodes, and

polarity protection diodes.

Maximum ratings are those values beyond which device damage can occur.

Maximum ratings applied to the device are individual stress limit values (not

normal operating conditions) and are not valid simultaneously. If these limits are

exceeded, device functional operation is not implied, damage may occur and

reliability may be affected.

1. The heat generated must be less than the thermal conductivity from

Junction−to−Ambient: dPD/dTJ < 1/RqJA.
