FFH30US30DN
30A, 300V Stealth?
Diode
General Description
The FFH30US30DN is a Stealth? diode optimized for low
loss performance in output rectification. The Stealth? family
exhibits low reverse recovery current (IRM(REC)), low VF and
soft recovery under typical operating conditions.
This device is intended for use as an output rectification diode
in Telecom power supplies and other power switching
applications. Lower VF and IRM(REC)
reduces diode losses.
Formerly developmental type TA49449.
