STK531-345A-E

Overview

The STK531-345A-E is a three-phase intelligent power module (IPM) manufactured by onsemi, designed for AC motor control applications. It integrates IGBT technology with logic interfaces to drive inductive loads. The module features a half-bridge output configuration across three channels, supporting continuous output currents of 10A per channel and peak currents up to 20A. It operates with a maximum load voltage of 450V and requires a supply voltage between 12.5V and 17.5V. Designed for robust performance, it functions within a junction temperature range of -40°C to 150°C. The component utilizes a 29-SIP package with molded leads for through-hole mounting and includes status flags and fault protection mechanisms such as current limiting and under-voltage lockout.

Feature Summary

Integrates IGBT-based half-bridge outputs for efficient three-phase AC motor inversion
Includes built-in fault protection mechanisms such as current limiting and under-voltage lockout
Provides status flag indicators for operational monitoring
Supports high-temperature operation suitable for demanding industrial environments

Applications

AC motor drives
Three-phase inverter circuits
Industrial motor control systems

Procurement Notes

Verify the exact part number against official onsemi documentation to ensure compatibility with specific design requirements. Confirm that the 29-SIP package and pinout match the target PCB layout. Ensure that the thermal management solution supports the specified junction temperature range of -40°C to 150°C. Validate that the input logic levels and supply voltage requirements align with the system's control circuitry before integration.

Selection Notes

Select this module when designing three-phase AC motor control systems requiring integrated protection and high reliability. Consider the 10A continuous and 20A peak current ratings to ensure adequate headroom for the intended load. Verify that the 450V blocking voltage meets the DC bus requirements of the application. Evaluate the thermal dissipation capabilities of the 29-SIP package against the expected operating conditions.
