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.
