MSS40-800

® MSS40 / 50 Series BACK TO BACK SCR MODULE MAIN FEATURES: Symbol IT(RMS) VDRM/VRRM IGT Value 55 and 70 800 and 1200 50 Unit A V mA G2 A2 G1 DESCRIPTION Packaged in ISOTOP modules, the MSS40 / MSS50 Series is based on two back-to-back SCR configurations, providing high noise immunity. They are suitable for high power applications such as solid state relays, heating control systems, welding equipment, motor control circuits... The compactness of the ISOTOP package allows high power density and optimized power bus connections. Thanks to their internal ceramic pad, they provide high voltage insulation (2500V RMS), complying with UL standards (File ref: E81734).
