Axial-Lead

Fast-Recovery Rectifiers

Axial–lead, fast–recovery rectifiers are designed for special applications such

as dc power supplies, inverters, converters, ultrasonic systems, choppers, low

RF interference and free wheeling diodes. A complete line of fast recovery

rectifiers having typical recovery time of 150 nanoseconds providing high

efficiency at frequencies to 250 kHz.
