DIODE
ULTRAFAST, LOW SWITCHING
LOSS RECTIFIER DIODE

DESCRIPTION
The UTC BYC8 is a rectifier diode. It provides the designers with
ultra-fast switching and low switching loss in associated MOSFET.
The UTC BYC8 is generally applied in continuous current
mode(CCM), power factor correction (PFC), half-bridge lighting
ballasts and half-bridge/full-bridge switched mode power supplies.

FEATURES
