Type SCM, Single/Dual IGBT Snubber Capacitor Modules 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. Pulse, Hi-Frequency & Snubber Capacitors Highlights • Mount directly to the IGBT module • Low inductance • Low Loss • Hyperfast diodes integrated into package • 1 or 2 wire taps for connecting external resistor • Flame resistant case and epoxy, meets UL 94VO • Other terminal pitches and capacitance values available. Discharge Restrictive De-coupling RCD Clamp 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. 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.
