Overview
The MCR12DSNT4G is a Silicon Controlled Rectifier (SCR) manufactured by Littelfuse, belonging to the MCR12DCX series. It features an 800 V rated repetitive off-state voltage and conducts a 12 A RMS on-state current. The device utilizes a DPAK-2 (TO-252-2) surface-mount package for SMD/SMT installation. Key electrical parameters include a maximum holding current of 40 mA, a gate trigger voltage of 1 V, and a gate trigger current of 20 mA. It operates within a temperature range of -40 °C to +125 °C.
Feature Summary
- Surface-mount construction in a compact DPAK-2 package for automated assembly
- High-voltage blocking capability suitable for demanding power control applications
- Robust thermal performance with a maximum operating junction temperature of 125 °C
Applications
- Industrial motor control circuits
- Solid-state relay implementations
- AC power switching systems
Procurement Notes
Verify the specific suffix 'NT' against the official Littelfuse datasheet to confirm tape-and-reel packaging specifications. Ensure the component meets RoHS compliance requirements for the target market. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.
Selection Notes
Select this SCR when an 800 V blocking voltage and 12 A continuous current rating are required in a surface-mount form factor. Compare the 1 V gate trigger voltage against available alternatives to ensure compatibility with the driving circuit's output capabilities. Verify that the DPAK-2 thermal resistance characteristics meet the system's heat dissipation needs under expected load conditions.
Part Context
This component belongs to the MCR12DCX family of high-power SCRs from Littelfuse. Related parts in this series include the MCR12DCNT4G and MCR12DSMT4G, which share similar current ratings but may differ in voltage ratings or packaging variations. These devices are designed for robust industrial and commercial power control applications requiring reliable thyristor switching.
Replacement Considerations
Potential substitutes include the MCR12DCNT4G and MCR12DSMT4G from the same Littelfuse series. Verify that alternative part numbers match the 800 V rating and DPAK-2 footprint. Confirm that gate trigger characteristics remain compatible with the existing drive circuitry before substitution.
