VRRM = 1200V
Description/ Features
The 8EWF12SPbF fast soft recovery QUIETIR
rectifier series has been optimized for combined
short reverse recovery time, low forward voltage
drop and low leakage current
The glass passivation ensures stable reliable
operation in the most severe temperature and
power cycling conditions.
Typical applications are both:
Output rectification and freewheeling diode
in inverters, choppers and converters.
Input rectifications where severe
restrictions on conducted EMI should be met.
