Preliminary
BYR79-600
ULTRA FAST-RECOVERY
RECTIFIER DIODE
DESCRIPTION
The UTC
BYR79-600
is a rectifier diode providing the designers
with ultra-fast switching and low switching loss. It features low
forward voltage drop, ultra fast reverse recovery times with very low
stored charge and soft-recovery characteristic.
The UTC
BYR79-600
is suitable for switched-mode power
supplies, SRPS and high-frequency circuits.
