Type SCD IGBT Snubber Capacitor Modules
Direct Mount
Applications
Snubber Capacitor
Style SCD offers protection against voltage transients in low to medium current
IGBTapplications 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.
