HEXFRED®
Ultrafast Soft Recovery Diode, 220 A
FEATURES
• Fast recovery time characteristic
• Electrically isolated base plate
• Large creepage distance between terminal
• Simplified mechanical designs, rapid assembly
• Designed and qualified for industrial level
• Material categorization: For definitions of compliance
please see www.vishay.com/doc?99912
DESCRIPTION/APPLICATIONS
The dual diode series configuration (VS-HFA220FA120) is
used for output rectification or freewheeling/clamping
1200 V
220 A at 38 °C
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.
