Low Inductance IGBT Snubbers | Cornell Dubilier (CDE)

CDE's 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. Style SCC is ideal for use in medium to high current applications where a dual IGBT module is used. This low loss snubber directly reduces turn-off voltage overshoots and is effective in reducing turn-on voltage transients. Use style SCM as a discharge restrictive de-coupling to protect dual IGBT modules from overvoltage. Style SCM may also be used as an “N” or “P” type snubber component for a clamp snubber where single IGBT modules are used.
