QM300HH-HMitsubishi - Power Transistor Module
QM300HH-H Description
The Mitsubishi Electric QM300HH-H is a Darlington transistor module rated at 600 V and 300 A. This type of device is widely used in motor drives, UPS systems and power supplies; transistor modules of this type are largely superseded by IGBTs in new designs but remain essential for maintaining installed equipment.
USComponent, a BBB A+ accredited business, helps engineers and maintenance teams source power semiconductors and industrial components, including older and hard-to-find part numbers. Please confirm ratings, package and pin-out against the manufacturer's datasheet before ordering, and request a quote for current pricing and lead time on the QM300HH-H.
Target Applications
Mitsubishi QM300HH-H is used for AC motor controllers, UPS, CVCF, DC motor controllers, NC equipment and Welders.
