• Power conversion equipment integrating inverter and brake rectifier stages in a single component.

Procurement Notes

This component is officially listed as obsolete or discontinued by the manufacturer, with records indicating this status as of August 11, 2021. Verification of availability requires checking authorized distributors for remaining stock or surplus channels. Sourcing should prioritize verified suppliers to ensure authenticity, as end-of-life components may have varying storage histories. Confirm the specific lot date code and physical condition before procurement to mitigate reliability risks associated with aged inventory.

Selection Notes

Select this module when a combined three-phase inverter and brake rectifier solution is required for 1200 V applications. Ensure the design accommodates the 25 A current rating and 138 W power dissipation limits under expected thermal conditions. The 26-DIP through-hole package dictates specific PCB layout requirements. Verify that the control circuitry can interface with the integrated NTC thermistor for accurate thermal management.

Part Context

The CP25TD1-24A belongs to Powerex's portfolio of discrete IGBT modules designed for medium-power industrial applications. It represents a consolidated solution combining switching and rectification functions, reducing component count compared to separate inverter and diode bridge assemblies. This integration targets cost and space optimization in motor control architectures where regenerative energy handling is necessary.

Replacement Considerations

As the part is discontinued, no official direct replacement from Powerex is confirmed in public documentation. Engineers must evaluate alternative three-phase inverter modules with integrated brake rectifiers from other manufacturers. Compatibility checks must focus on matching the 1200 V/25 A ratings, 26-DIP footprint, and thermal resistance characteristics to ensure seamless mechanical and electrical substitution.
