QUIETIR Series 8EWF..S
SURFACE MOUNTABLE FAST SOFT RECOVERY DIODE VF trr < 1.3V @ 8A = 80ns
VRRM 1000 to 1200V
Description/Features
The 8EWF..S 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.
