ULTRA FAST RECOVERY RECTIFIER DIODES
Low cost single chip rectifier suited for switchmode
power supply and high frequency DC to DC conver-
ters.
Packaged in TO220AC and ISOWATT220AC, this
device is intended for use in low voltage, high fre-
quency inverters, free wheeling and polarity protec-
tion applications.
