Description/Features
The 20ETF..S 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.
