Preliminary
RECTIFIER DIODE,
HYPERFAST

DESCRIPTION
The UTC BYC20 is a rectifier diode. It provides the designers
with ultra-fast switching and low switching loss in associated
MOSFET.
The UTC BYC20 is ideally used in half-bridge lighting ballasts,
half-bridge/full-bridge switched mode power supplies and continuous
current mode (CCM) power factor correction (PFC).

FEATURES
* Low Reverse Recovery Current
* Ultra-Fast Switching
* Low Switching Loss In Associated MOSFET
* Low Thermal Resistance
