Procurement Notes

Verify the specific suffix requirements when ordering. The 'P' suffix indicates a lead-free leadframe, whereas the 'EP' variant may have different material specifications or compliance standards. Confirm availability status as these modules are subject to lifecycle changes. Ensure the datasheet version matches the production batch for accurate thermal and electrical parameters.

Selection Notes

Select this module for applications requiring integrated motor drive solutions with built-in protection. Consider the thermal resistance values and mounting torque requirements for proper heatsinking. Verify that the control supply voltage ranges align with the system's logic levels. Evaluate the PWM input frequency limits to ensure compatibility with the controller's switching speed.

Part Context

This component belongs to the Intellimod™ series of intelligent power modules designed for driving small three-phase motors. It represents a solution for reducing overall inverter size by consolidating multiple discrete components into a single hybrid package. The DIP packaging facilitates through-hole mounting on printed circuit boards.

Replacement Considerations

Check for updated revisions within the PS21255 series. Verify pinout compatibility if substituting with other IPMs from the same manufacturer. Ensure thermal performance metrics match the original design constraints.

FAQ

What is the maximum junction temperature rating?

The maximum junction temperature rating is 150°C, though safe operation typically requires limiting the average junction temperature to 125°C.

How does the module handle short circuit protection?

It includes self-protection capabilities with a supply voltage limit of 400 Volts for short circuit scenarios, functioning primarily at the low-arms.

What type of isolation voltage does the module provide?

The module provides an isolation voltage of 2500 Volts AC for one minute at 60Hz between the connection pins and the heatsink plate.
