Ultrafast Soft Recovery Diode, 80 A
HFA80FA120P
Vishay High Power Products
FEATURES
• Fast recovery time characteristic
• Electrically isolated base plate
• Large creepage distance between terminal
• Simplified mechanical designs, rapid assembly
• UL pending
• Totally lead (Pb)-free
• Designed and qualified for industrial level
DESCRIPTION/APPLICATIONS
The dual diode series configuration (HFA80FA120P) is used
for output rectification or freewheeling/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.
