QM300HA-2H Mitsubishi - Power Transistor Module

QM300HA-2H Description

Mitsubishi Electric QM300HA-2H is a Darlington transistor module rated at 1000 V and 300 A. It was a workhorse in drives and power supplies before IGBTs took over, and it is still needed to repair that equipment.

USComponent has been supplying power semiconductors since 2001, including discontinued and hard-to-find part numbers.
