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).
