CP20TD1-12A

Overview

The CP20TD1-12A is a DIP-CIB module integrating a three-phase diode converter, a three-phase inverter, and a brake circuit within a single low-profile transfer mold package. It utilizes 5th Generation CSTBT chips to achieve low switching losses. The inverter section supports a collector-emitter voltage of 600 Volts with a DC collector current of 20 Amperes at TC = 78°C. The brake section provides a DC collector current of 10 Amperes at TC = 110°C. The converter section features a repetitive peak reverse voltage of 800 Volts and a DC output current of 20 Amperes. An integrated NTC thermistor allows for baseplate temperature sensing, while open emitters facilitate accurate phase current monitoring.

Procurement Notes

Verify the specific ordering suffix against official Powerex documentation to confirm exact electrical ratings and pinout configurations. Ensure that the procurement channel sources genuine components from authorized distributors or the manufacturer directly. Confirm RoHS compliance status if required by local regulations. Check for any updated datasheet revisions that may affect mounting torque specifications or thermal resistance values before finalizing orders.

Selection Notes

Select this component when a combined rectifier, inverter, and dynamic braking function is required in a space-constrained design. The 600V rating suits standard industrial AC bus voltages. Verify that the thermal interface material application meets the specified case-to-fin thermal resistance requirements. Ensure the gate drive circuitry can accommodate the recommended external gate resistance ranges for both the inverter and brake sections to optimize switching performance.

Part Context

This module belongs to the DIP-CIB family of power modules designed for medium-power switching applications. It consolidates multiple power stages typically found in separate discrete components or larger assemblies. The DIP-CIB series offers a standardized footprint, allowing designers to utilize a single package type across various current and voltage ratings within the same product line, simplifying mechanical design and inventory management.

Replacement Considerations

Direct replacements must match the DIP-CIB topology and physical dimensions. Verify that substitute modules maintain equivalent 600V ratings and comparable current capacities for all three internal sections. Ensure the replacement part includes open emitters and an integrated thermistor if these features are critical to the existing control loop design.
