DIODE
ULTRA FAST-RECOVERY
RECTIFIER DIODE
DESCRIPTION
The UTC
BYR79
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
is suitable for switched-mode power supplies,
SRPS and high-frequency circuits.
FEATURES
* Low Switching Loss
* Low Forward Volt Drop
* Ultra-Fast Switching
* Soft Recovery Characteristic
* Low Thermal Resistance
