SCM1272MA

Overview

The SCM1272MA is a high-voltage three-phase motor driver manufactured by Sanken Electric. It integrates transistors, pre-driver circuits, and bootstrap diodes with current limiting resistors into a single module. Designed for inverter systems controlling medium-capacity motors, it supports three-shunt current detection architectures. The device features an isolation voltage of 2000 V (1 minute) and includes UL recognition under file number E118037. It incorporates temperature sensing capabilities and fault protection mechanisms that disable all outputs via connected FO pins during abnormal operations.
