Description

RIR120CDM040B 1200V Silicon Carbide (SiC) MPS Diode (40A) (1 tube of 30 units)

The RIR120CDM040B is a high-performance 1200V Merged PiN Schottky (MPS) Silicon Carbide Diode engineered for high-efficiency, high-frequency power conversion in demanding industrial and energy applications. Designed with no reverse recovery current and a low forward voltage, this device minimises switching losses and enhances overall system efficiency, particularly in fast-switching power electronics.

Built for durability and reliable operation in harsh environments, the RIR120CDM040B supports a maximum junction temperature of 175°C, offers high surge current capability, and maintains fast switching performance independent of temperature. These characteristics make it ideal for modern power systems including EV charging, solar inverters, power factor correction, and industrial motor drives.

Supplied in a TO-247-2L package, the device provides excellent thermal performance and high current handling while meeting RoHS, Pb-free, and halogen-free environmental standards.
