STK621-728B-E

Overview

The STK621-728B-E is a half-bridge driver IC designed for AC motor applications using IGBTs. It is housed in a 21-SIP package and functions as a power management integrated circuit (PMIC) specifically engineered for motor driver systems.

Feature Summary

Designed for half-bridge configurations
Compatible with IGBT-based AC motor drives

Applications

AC motor drive systems
IGBT half-bridge control circuits

Procurement Notes

Verify the exact suffix 'B' against official onsemi documentation to confirm specific pinout or thermal characteristics, as variations within the STK621 series exist. Ensure compatibility with the target IGBT voltage ratings and switching frequencies specified in the datasheet before procurement.

Selection Notes

Select this component when a dedicated half-bridge driver for IGBTs is required. Consider the 21-SIP package constraints and verify that the internal protection features meet the safety requirements of the specific AC motor application environment.

Part Context

This part belongs to the STK621 series of hybrid ICs from onsemi, which are widely used in industrial motor control. The series includes variants like the STK621-061-E for three-phase inverters, while this model focuses on half-bridge topology.

Replacement Considerations

STK621-728S-E and STK621-728-E are related variants within the same product family. Verify electrical and mechanical compatibility before substitution.
