HFA80FA120
HEXFRED
TM
Ultrafast, Soft Recovery Diode
Features
• Fast Recovery Time Characteristic
• Electrically Isolated Base Plate
• Large Creepage Distance Between Terminal
• Simplified Mechanical Designs, Rapid Assembly
Description/ Applications
The dual diode series configuration (HFA80FA120) is used for output rectification
or frewheeling/ clamping operation and high voltage application.
The semiconductor in the SOT-227 package is isolated from the copper base
plate, allowing for common heatsinks and compact assemblies to be built.
These modules are intended for general applications such as HV power
supplies, electronic welders, motor control and inverters.
