Description

Overview

The 2MBI300S‑120 is a high‑power IGBT (Insulated Gate Bipolar Transistor) module manufactured by Fuji Electric (also sometimes seen stocked as a module part). It is designed for high‑current, high‑voltage power switching applications in industrial electronics.

⚙️ Key Specifications

  • Type: Dual IGBT power module (two IGBTs in one package)

  • Collector‑Emitter Voltage (V<sub>CE</sub>): 1200 V

  • Rated Collector Current: 300 A continuous

  • Gate‑Emitter Voltage: ±20 V

  • Total Power Dissipation: ~1600–2500 W (varies with temp/conditions)

  • Isolation Voltage: ~2500 V

  • Operating Temperature: ~‑40 °C to +150 °C

  • Package: Screw‑mountable module type

🔧 Characteristics

  • High‑speed switching: Suitable for efficient power conversion with low switching losses.

  • Low on‑state voltage drop: Improves efficiency in heavy‑current circuits.

  • Two IGBTs + built‑in diodes: Typically configured in a half‑bridge arrangement, ideal for driving AC loads.

⚙️ Typical Applications

This module is used in systems requiring robust power control and switching:

  • Motor drives and variable frequency drives (VFDs) for AC/DC motors.

  • Inverters (solar, industrial, UPS).

  • Industrial machinery and welding systems needing high current switching.

  • Power supplies and HVAC control systems.
