FAST SOFT RECOVERY
RECTIFIER DIODE
VF < 1.31V @ 20A
Lead-Free ("PbF" suffix)
IFSM = 355A
VRRM= 1200V
Description/ Features
The 20ETF12SPbF fast soft recovery QUIETIR
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.
