1N4935 and 1N4937 are Preferred Devices
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.
