DSF21545SV
Fast Recovery Diode
DS4153- JXO\(LN31805)
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.
