DSF21545SV_04 Datasheet, PDF (1/7 Pages) Dynex Semiconductor – Fast Recovery Diode

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