Preferred Device

SWITCHMODEt

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.

Features

•Highly Stable Oxide Passivated Junction

•Very Low Forward Voltage Drop

•Matched Dual Die Construction

•High Junction Temperature Capability

•High dv/dt Capability

•Guardring for Stress Protection

•Epoxy Meets UL 94 V−0 @ 0.125 in

•Electrically Isolated. No Isolation Hardware Required.

•Pb−Free Package is Available*

Mechanical Characteristics:

•Case: Epoxy, Molded

•Weight: 1.9 Grams (Approximately)

•Finish: All External Surfaces Corrosion Resistant and Terminal

Leads are Readily Solderable

•Lead Temperature for Soldering Purposes:

260°C Max. for 10 Seconds

*For additional information on our Pb−Free strategy and soldering details, please
