QM30HA-H Mitsubishi - Power Transistor Module
QM30HA-H Description
The QM30HA-H from Mitsubishi Electric is a Darlington transistor module with a 600 V / 30 A rating. It was a workhorse in drives and power supplies before IGBTs took over, and it is still needed to repair that equipment.
USComponent (Young & New Century LLC) supplies power modules, thyristors, diodes and other industrial components, including legacy parts. Contact us for a quote on the QM30HA-H, and please confirm ratings against the datasheet before ordering.
