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.
