Discharge Restrictive De-coupling

The circuit in Figure 1 operates on the same principles

as the de-coupling capacitor, but only during turn-off

switching. As the IGBT turns off, 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.

Applications

Use style SCM as a discharge restrictive de-coupling to

protect dual IGBT modules from overvoltage, Figure

1. Style SCM may also be used as an “N” or “P” type

snubber component for a clamp snubber where single

IGBT modules are used, Figure 2.

• Flame resistant case and epoxy, meets UL 94V0

• Other terminal pitches and capacitance values

RCD Clamp

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

2. At turn-off, 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.
