SICW30120DG5M Silicon Carbide Schottky Barrier Diode (SiC SBD) Featuring Zero Reverse Recovery, Low Forward Voltage, and High Surge Capability for Next-Generation Power Systems

Micro Commercial Components (MCC) introduces the SICW30120DG5M-BP, a high-performance 1200V, 30A Silicon Carbide (SiC) Schottky Barrier Diode designed to maximize efficiency in high-voltage, high-frequency power conversion systems. As modern power electronics continue to demand greater efficiency, higher switching frequencies, and increased power density, engineers require rectifier solutions that minimize switching losses while delivering outstanding thermal performance and long-term reliability.

The SICW30120DG5M-BP addresses these challenges by combining a 1200V reverse voltage rating with a 30A average forward current capability in an industry-standard TO-247AB package. Built on advanced Merged PiN Schottky (MPS) Silicon Carbide technology, the device features zero reverse recovery current, a low forward voltage of only 1.6V, high surge current capability of 180A, and a maximum junction temperature of 175°C. These characteristics make it an excellent choice for switching mode power supplies (SMPS), power factor correction (PFC), EV charging infrastructure, motor drives, renewable energy systems, and industrial power conversion equipment.
