PS21962-4S

Overview

The PS21962-4S is a Dual-In-Line Intelligent Power Module (IPM) manufactured by Powerex Inc. It integrates power devices, drivers, and protection circuitry in an ultra-compact dual-in-line transfer-mold package designed for driving small three-phase motors. The module utilizes fifth-generation IGBTs and application-specific high-voltage integrated circuits (HVICs). Key electrical parameters include a current rating of 3 Amperes and a voltage rating of 600 Volts. It requires a supply voltage range of 0V to 400V. The device operates within a temperature range of -20°C to 100°C and features a 25-pin configuration.

Procurement Notes

Verify the specific suffix '4S' against official Powerex documentation to confirm pinout compatibility and exact electrical ratings. Ensure the required 0V to 400V supply voltage aligns with your system design. Confirm the operating temperature range meets your environmental requirements. Cross-reference the 25-pin DIP package dimensions with your PCB layout. Validate that the 3A/600V ratings suit your motor load specifications.

Selection Notes

Select this component for applications requiring a compact solution for small three-phase motor drives. The integration of HVICs simplifies the design process by reducing overall inverter size. Consider the 3A current limit when sizing for motor loads. The DIP packaging facilitates easier prototyping compared to surface-mount alternatives. Ensure the single power supply requirement fits your power architecture constraints.

Part Context

The PS21962-4S belongs to the PS219xx series of Intelligent Power Modules from Powerex. This series is characterized by the use of fifth-generation IGBTs and dedicated HVICs. These modules are engineered to replace discrete component solutions, offering a significant reduction in board space and design time. The series is widely used in household appliances and small industrial motor control applications.

Replacement Considerations

Check for compatible parts within the PS219xx series, such as the PS21962-4W or PS21961, ensuring pinout and rating equivalence. Verify if alternative IPMs from other manufacturers offer similar 3A/600V specifications in a DIP format. Confirm functional compatibility regarding driver logic and protection thresholds before substitution.
