M252571

Overview

The M252571 is a power SCR module from the Sensata-Crydom M Series, designed for high-current applications. It features a 300V repetitive peak off-state voltage and a continuous on-state current of 25A. The device utilizes a common cathode configuration with two SCRs in a chassis mount package. Key electrical parameters include a maximum gate trigger voltage of 3V and a non-repetitive surge current rating of 1500A at 60Hz. It operates within a junction temperature range of -40°C to 125°C.

Feature Summary

• Common cathode configuration for simplified circuit design
• Chassis mount construction for robust mechanical stability
• High surge current capability for transient protection

Applications

• Industrial motor drives
• Power supply rectification
• Heating control systems

Procurement Notes

Verify component authenticity through authorized distributors. Confirm datasheet revisions match production batches. Check for RoHS compliance status if required by project specifications. Ensure storage conditions maintain moisture sensitivity level integrity prior to soldering.

Selection Notes

Select this module when a 300V rating and 25A continuous current are sufficient for the load. The common cathode layout simplifies control logic compared to isolated configurations. Evaluate thermal management requirements based on the 125°C junction limit and chassis mounting surface area.

Part Context

Part of the M Series power modules, this component integrates silicon controlled rectifiers into a single unit. It replaces discrete SCR assemblies, reducing board space and interconnection complexity. The series is known for reliability in industrial environments requiring precise power switching.

Replacement Considerations

Check pinout compatibility and thermal resistance values against potential substitutes. Verify that alternative modules support the same 300V blocking voltage and 25A current capacity. Ensure the replacement maintains the common cathode topology for direct circuit integration.
