Preliminary
DIODE
RECTIFIER DIODE ULTRAFAST

DESCRIPTION
The UTC BYR29 is a rectifier diode and It provides the designers
with ultra-fast switching and low switching loss.
The UTC BYR29 is suitable for half-bridge lighting ballasts,
half-bridge/full-bridge switched mode power supplies and active
power factor correction.
