Type SCD, IGBT Snubber Capacitor Modules
Style SCD
Applications
Direct Mount
Style SCD offers protection against voltage transients in low to medium current IGBT applications
where high dV/dt is encountered. Connect these
capacitors from C1 to E2 on a dual IGBT module
or from P to N on a six-pack module to eliminate
severe voltage transients. Parts ending with Z25 fit
IGBTs with 23mm, 25mm and 28mm lead spacing. If you have a preferred lead spacing, please
specify.

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.

& 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.
