Type SCMT
Single/Dual IGBT Snubber Capacitor Modules
Applications
Use style SCMT as a discharge restrictive de-coupling to protect
dual IGBT modules from overvoltage, Figure 1. Style SCMT
may also be used as an “N” or “P” type snubber component for a
clamp snubber where single IGBT modules are used, Figure 2.

RoHS Compliant
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.
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.
