Discharge Restrictive De-coupling

The circuit in Figure 1 operates on the same principles as the

de-coupling capacitor, but only during turn-o switching. As

the IGBT turns o, energy trapped in the loop inductance is

transferred to the capacitor. The diode blocks oscillations from

occurring and excess charge on the capacitor is discharged

through the external resistor.

• Flame resistant case and epoxy, meets UL 94V0

• Other terminal pitches and capacitance values

available.

RCD Clamp

The function of this snubber is similar to a clamp, Figure 2. At

turn-o, the snubber diode is forward biased and the snubber

is activated. The energy trapped in the stray inductance is

absorbed by the snubber capacitor. During turn-on the snubber

caps that were fully charged to bus voltage have a discharge

path through the forward biased free-wheel diode, the IGBT,

and the snubber resistors. This reduces the reverse recovery

voltage transient.
