FFH30US30DN
30A, 300V StealthTM Diode
General Description
The FFH30US30DN is a StealthTM diode optimized for low loss performance in output rectification. The StealthTM 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.
