ULTRAFAST RECOVERY RECTIFIERS

Reverse Voltage – 50 to 1000 V

Forward Current – 1 A

Features

• Plastic package has Underwriters Laboratories

Flammability Classification 94V-0

• Ideally suited for use in very high frequency switching

power supplies, inverters and as free wheeling diodes

• Ultrafast recovery time for high efficiency

• Excellent high temperature switching

• Soft recovery characteristics

Mechanical Data

• Case: molded plastic, DO-41

• Epoxy: UL 94V-0 rate flame retardant

• Lead: Axial leads, solderable per MIL-STD-202,

Method 208 guaranteed

• Polarity: Color band denotes cathode end

• Mounting Position: Any

Absolute Maximum Ratings and Characteristics

Ratings at 25 C ambient temperature unless otherwise specified. Single phase, half wave, 60 Hz, resistive or

inductive load. For capacitive load, derate current by 20%.
