STK551-391A-E

Overview

The STK551-391A-E is a three-phase Intelligent Power Module (IPM) manufactured by onsemi. It integrates power switching components designed for motor control applications. The device utilizes silicon technology and is housed in a SIP-29 package suitable for through-hole mounting. Key electrical specifications include a maximum collector-emitter voltage of 600 V and a power dissipation rating of 39 W. The module operates within a temperature range of -40°C to +100°C.

Feature Summary

Integrates three-phase power switching capabilities within a single compact module
Designed for robust thermal stability and efficient heat dissipation
Supports high-voltage operation with integrated protection features

Applications

Office automation equipment motors
Camera phone and digital camera actuators
General purpose three-phase motor drives

Procurement Notes

Verify component authenticity due to end-of-life status. Confirm package integrity and pin alignment against the SIP-29 specification. Check for RoHS compliance documentation as required by regional regulations. Ensure storage conditions maintain moisture sensitivity levels prior to soldering.

Selection Notes

Select this IPM for applications requiring integrated three-phase inversion with simplified thermal management. Consider the 600 V rating for medium-voltage AC motor drives. Evaluate the SIP-29 footprint against available PCB real estate. Verify that the 39 W power dissipation aligns with the system's cooling capacity.

Part Context

This component belongs to onsemi's STK551 series of intelligent power modules. These modules are engineered to simplify the design of three-phase motor drive systems by combining power transistors and driver circuits. The series targets consumer electronics and office automation markets where space efficiency and reliability are critical.
