Rectifier Device Data

Preliminary Data Sheet

POWERTAP II

SWITCHMODE™ Power Rectifiers

. . . using the Schottky Barrier principle with a platinum barrier metal. These

state–of–the–art devices have the following features:

• Dual Diode Construction — May Be Paralleled for Higher Current Output

• Guardring for Stress Protection

• Low Forward Voltage

• 175°C Operating Junction Temperature

• Guaranteed Reverse Avalanche

Mechanical Characteristics:

• Case: Epoxy, Molded with metal heatsink base

• Weight: 80 grams (approximately)

• Finish: All External Surfaces Corrosion Resistant

• Top Terminal Torque: 25–40 lb–in max

• Base Plate Torques: See procedure given in the

Package Outline Section

• Shipped 25 units per foam

• Marking: B20045T, B20060T
