Rectifier Device Data

SWITCHMODE™

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.

• 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″

• Electrically Isolated. No Isolation Hardware Required.

• UL Recognized File #E69369
