Schottky Power Rectifier

The SWITCHMODE Power Rectifier employs the Schottky Barrier principle in

a large area metal鈥搕o鈥搒ilicon power diode. State鈥搊f鈥搕he鈥揳rt geometry features

epitaxial construction with oxide passivation and metal overlay contact. Ideally

suited for use as rectifiers in very low鈥搗oltage, high鈥揻requency switching power

supplies, free wheeling diodes and polarity protection diodes.

鈥?/div>

Highly Stable Oxide Passivated Junction

Very Low Forward Voltage Drop

Matched Dual Die Construction

High Junction Temperature Capability

High dv/dt Capability

Excellent Ability to Withstand Reverse Avalanche Energy

Transients

Guardring for Stress Protection

Epoxy Meets UL94, VO at 1/8鈥?/div>

Electrically Isolated. No Isolation Hardware Required.
