Axial Lead Fast
Recovery Rectifiers
Axial lead mounted fast recovery power 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 100 nanoseconds providing high efficiency at
frequencies to 250 kHz.
Features
