MCD312-16IO1

The MCD312-16IO1 is a robust thyristor-diode module engineered for heavy industrial and commercial power-control applications, delivering reliable switching and high surge capability in a compact Y1-CU package. Designed by IXYS (now distributed under Littelfuse/IXYS channels), this module supports repetitive peak reverse voltages up to 1600 V and is intended for continuous average forward currents in the ~320 A range, making it ideal for motor control, soft starters, power converters, industrial furnaces and lighting control systems where dependable high-power rectification and controlled switching are required.

Built for efficiency and long life in demanding environments, the MCD312-16IO1 uses direct copper-bonded Al₂O₃ ceramic with a copper base plate and planar passivated chips to reduce thermal resistance and improve power cycling performance; typical key electrical characteristics include a low threshold on-voltage (~0.8 V), a low dynamic resistance for power-loss calculations (~0.68 mΩ), fast dv/dt immunity (≈1000 V/µs) and very high surge ratings (multiple kA peak currents), which together minimise conduction losses and reduce cooling requirements in system designs. These attributes translate to higher system efficiency, lower thermal stress on the powertrain, and greater durability under repetitive load and surge events.

From an integration and reliability standpoint the module provides a 3600 V isolation rating, keyed gate/cathode twin pins for secure connections, wide operating temperature range and UL registration for industrial deployment; its standardized mechanical footprint and screw-mount terminals simplify installation and replacement in retrofit or new designs. The MCD312-16IO1 is therefore well suited for OEMs and system integrators looking for a proven, high-current thyristor/diode building block that balances performance, durability and straightforward thermal management.
