SEMICONDUCTOR TECHNICAL DATA
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.
