DIODE
ULTRAFAST, LOW SWITCHING
LOSS RECTIFIER DIODE
DESCRIPTION
The UTC
BYC5
is a rectifier diode. It provides the designers with
ultra-fast switching and low switching loss.
The UTC
BYC5
is suitable for half-bridge lighting ballasts,
half-bridge/full-bridge switched mode power supplies and active power
factor correction applications.
FEATURES
* Low Reverse Recovery Current
* Ultra-Fast Switching
* Low Switching Loss
* Low Thermal Resistance

Fig.1. Typical application, output rectifier in boost
converter power factor correction circuit. Continuous
conduction mode, where the transistor turns on
whilst forward current is still flowing in the diode.
Fig.2. Typical application, freewheeling diode in half
bridge converter. Continuous conduction mode, where
each transistor turns on whilst forward current is still
flowing in the other bridge leg diode.
