Vishay releases 1,200 V SiC MOSFET power modules for EV chargers in SOT-227 package

Vishay Intertechnology has introduced five 1,200 V silicon carbide (SiC) MOSFET power modules in the industry-standard SOT-227 package: VS-SF50LA120, VS-SF50SA120, VS-SF100SA120, VS-SF150SA120 and VS-SF200SA120. Vishay says the modules target medium- to high-frequency power conversion, where switching losses and thermal headroom limit efficiency, including EV offboard, switched-mode power supplies (SMPS), DC-to-DC converters, uninterruptible power supplies (UPS), heating, ventilation, and air conditioning (HVAC) systems and telecom power supplies.

Vishay says the modules are offered in single-switch and low-side-chopper configurations and integrate a SiC MOSFET with a soft body diode designed for low reverse recovery. This combination reduces switching losses and increases efficiency in the listed inverter and converter use cases.

The modules are built in a compact SOT-227 molded package and serve as a drop-in replacement for competing SOT-227 solutions, avoiding printed-circuit-board (PCB) layout changes. Vishay says the package provides electrical insulation up to 2,500 V for one minute, which it says can eliminate the need for additional insulation between the component and heatsink.

Across the family, Vishay specifies continuous drain current ratings from 50 A to 200 A, with on-resistance down to 12.1 mΩ, plus high-speed switching with low capacitance. The company lists a maximum operating junction temperature of +175 °C and says the devices are Restriction of Hazardous Substances (RoHS)-compliant. Vishay reports samples and production quantities are available now, with lead times of 13 weeks.
