PS21254-EP

Overview

The PS21254-EP is a Dual-In-Line Intelligent Power Module (IPM) from the Intellimod™ series by Powerex Inc. It integrates 4th generation IGBT power devices, gate drivers, and protection circuitry into a compact dual-in-line transfer-mold package. The module is rated for 600 Volts collector-emitter voltage and 15 Amperes continuous collector current. It features integrated high-voltage ICs (HVICs) allowing direct CPU connection and single power supply operation. Key electrical parameters include a maximum junction temperature of 150°C, isolation voltage of 2500V AC, and short-circuit protection capability up to 400V.

Feature Summary

• Integrates power devices, drivers, and protection circuitry in a compact dual-in-line package
• Utilizes 4th generation IGBT technology for reduced inverter size
• Features application-specific HVICs enabling direct CPU connection
• Operates with a single power supply configuration

Applications

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

Procurement Notes

Verify the specific suffix requirements when ordering. The datasheet notes that a 'P' suffix designates a lead-free leadframe, whereas the base model PS21254-EP does not explicitly state lead-free status in the provided text. Confirm thermal interface material specifications and mounting torque requirements (13 in-lb for M4 screws) during procurement planning to ensure proper installation and thermal performance.

Selection Notes

Select this module for applications requiring small three-phase motor drive solutions where space constraints are critical. The DIP packaging facilitates easier integration compared to larger power modules. Ensure the control supply voltage remains within the 13.5V to 16.5V range and verify that the PWM input frequency does not exceed 15 kHz under recommended operating conditions.

Part Context

The PS21254-EP belongs to Powerex's Intellimod™ family of intelligent power modules. These modules are designed to simplify inverter design by combining power switching elements with control logic. The DIP format distinguishes it from surface-mount or larger insulated gate bipolar transistor modules, targeting low-to-medium power appliance and motor control markets.

Replacement Considerations
