QM30DY-H Mitsubishi - Power Transistor Module

QM30DY-H Description

QM30DY-H is a 600 V, 30 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.

We help engineers and repair technicians find parts like the QM30DY-H, including obsolete ones. Send a quick RFQ for current pricing and delivery. Before ordering, please confirm ratings and pin-out with the official datasheet.
