Description/ Features
The 40EPF12PbF fast soft recovery
QUIET
IR
rectifier series has been optimized for combined
short reverse recovery time and low forward
voltage drop.
The glass passivation ensures stable reliable
operation in the most severe temperature and
power cycling conditions.
Typical applications are both:
output rectification and freewheeling in
inverters, choppers and converters
and input rectifications where severe
restrictions on conducted EMI should be met.
