QUIETIR Series 20ETF..S
SURFACE MOUNTABLE FAST SOFT RECOVERY RECTIFIER DIODE VF < 1.2V @ 10A
IFSM = 300A VRRM 200 to 600V
Description/Features
The 20ETF..S soft recovery rectifier QUIETIR 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.
