Toshiba — MG300J1US51 IGBT Power Module 600 V • 300 A • Single N-Channel IGBT • Built-In Freewheel Diode • Isolated Baseplate
What it is

The Toshiba MG300J1US51 is a high-current 600 V, 300 A N-channel IGBT power module designed for industrial switching and power-conversion applications. Unlike Toshiba’s J2 two-element modules, the MG300J1US51 uses a single-switch / 1U configuration with an integrated reverse-connected freewheel diode.

Its high current capability and isolated power-module construction make it suitable for industrial inverters, motor drives, UPS systems, DC choppers, welding equipment and other high-power switching circuits. The electrically isolated mounting base simplifies integration with an appropriate heatsink.

At-a-Glance
  • Voltage Rating: 600 V
  • Current Rating: 300 A
