QM300HA-H Mitsubishi - Power Transistor Module

QM300HA-H Description

QM300HA-H is a 600 V, 300 A Darlington transistor module made by Mitsubishi Electric. It was a workhorse in drives and power supplies before IGBTs took over, and it is still needed to repair that equipment.

USComponent has sourced power semiconductors for maintenance teams and OEMs since 2001. For price and availability of the QM300HA-H, send us a request for quote. Please confirm the specifications against the manufacturer's datasheet before purchase.
