QM300HA-24BMitsubishi - Power Transistor Module

QM300HA-24B Description

The Mitsubishi Electric QM300HA-24B is a Darlington transistor module rated at 1200 V and 300 A. HIGH POWER SWITCHING USE INSULATED TYPE APPLICATION AC motor controllers UPS CVCF DC motor controllers NC equipment Welders. 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of device is widely used in motor drives, UPS systems and power supplies; transistor modules of this type are largely superseded by IGBTs in new designs but remain essential for maintaining installed equipment.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 QM300HA-24B.
