PS21245-EP

Overview

The Powerex PS21245-EP is a Dual-In-Line Intelligent Power Module (IPM) rated at 600 Volts and 20 Amperes. It integrates 4th generation IGBTs, application-specific HVICs, and protection circuitry within a compact dual-in-line transfer-mold package. Designed for driving small three-phase motors, it supports a maximum junction temperature of 150°C and an operating case temperature up to 100°C. The module features a single power supply configuration with integrated short-circuit protection capability limited to 400V.

Feature Summary

• Integrates power devices, drivers, and protection circuitry in a compact dual-in-line package
• Utilizes 4th generation IGBTs and application-specific HVICs to reduce inverter size
• Features direct connection capability to CPU via control sector inputs
• Includes self-protection against short circuits and under-voltage conditions

Applications

• Washing Machines
• Refrigerators
• Air Conditioners
• Small Servo Motors
• Small Motor Control

Procurement Notes

Verify the specific suffix requirements for lead-free leadframes when sourcing replacements or equivalents. Confirm that the intended application operates within the specified thermal limits, particularly the case temperature constraint of 100°C. Ensure the control supply voltage remains within the 13.5V to 16.5V range for proper operation of the integrated HVICs and protection logic.

Selection Notes

Select this module for applications requiring a compact solution for small three-phase motor drives where space constraints are critical. The integration of drivers and protection reduces design time and board space compared to discrete solutions. Consider the thermal resistance characteristics and the need for adequate heatsinking to maintain the case temperature below 100°C during continuous operation.

Part Context

This component belongs to the Intellimod™ series of intelligent power modules from Powerex Inc. These modules are designed to simplify the implementation of inverter circuits by combining power switching elements with necessary gate drive and protection functions. The DIP packaging format facilitates through-hole mounting on printed circuit boards commonly used in consumer appliance manufacturing.
