MCR12DSN-1G

Overview

The MCR12DSN-1G is a sensitive gate Silicon Controlled Rectifier (SCR) manufactured by Littelfuse Inc. It is designed for surface mount applications in the TO-252 (DPAK) package, also referred to as IPAK. The device supports an 800V repetitive peak off-state voltage and handles a 12A RMS on-state current. Key electrical parameters include a maximum surge current of 100A, a holding current of 100mA, and a gate trigger current of 20mA. It operates within a junction temperature range of -40°C to +110°C.

Feature Summary

Sensitive gate architecture for reliable triggering with low gate power requirements
Surface mount construction in a TO-252 package for automated assembly
High surge current capability for robust performance in industrial environments

Applications

Motor control circuits
Process control systems
Industrial consumer applications

Procurement Notes

Verify the specific suffix '1G' against the manufacturer's latest datasheet to confirm RoHS compliance and lead-free status. Ensure the ordering part number matches the required TO-252 package variant. Cross-reference the 800V rating and 12A current specifications with the target circuit design requirements before finalizing procurement.

Selection Notes

Select this component when a surface mount SCR is required for high-volume industrial or consumer applications. The sensitive gate feature allows for efficient drive circuitry. Verify that the TO-252 footprint aligns with the PCB layout. Confirm thermal management capabilities are sufficient for the expected RMS current and ambient operating conditions.

Part Context

This device belongs to the MCR12DSN series of SCRs from Littelfuse. It is part of a family of low-power thyristors designed for cost-effective solutions. The series includes variants with different voltage ratings and packages, such as through-hole options, but this specific model is optimized for surface mount integration.

Replacement Considerations

Potential substitutes include other 800V 12A SCRs in TO-252 packages, such as the MCR12DCNT4G or MCR12DSMT4G, provided they meet the same electrical and mechanical specifications.
