DSF21545SV45

DSF21545SV DSF21545SV Fast Recovery Diode Replaces March 1998 version, DS4153-3.1 DS4153-4.0 January 2000 APPLICATIONS s The DSF21545SV is a purpose designed freewheel diode to complement the DG858BW GTO in inverter circuits, using energy recovery snubbers. FEATURES s The DSF21545SV is designed for fast turn-on thus minimising reverse current through the GTO. s Low recovered charge for low losses. s DSF21545SV is housed in a similar outline to that of the DG858BW therefore offering complete mechanical compatibility for parallel and series clamping.
