MCR8DCNT4G

Overview

The MCR8DCNT4G is a Silicon Controlled Rectifier (SCR) from Littelfuse, designed for surface mount applications in the DPAK-3 (TO-252-3) package. It features an 800 V rated repetitive off-state voltage and supports a non-repetitive on-state current of 8 A. The device operates within a temperature range of -40°C to +125°C. Key electrical parameters include a maximum holding current of 35 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 35 mA. The component exhibits a low on-state voltage of 1.6 V and maintains an off-state leakage current of 10 µA at VDRM.

Feature Summary

Surface Mount Construction: Designed for automated assembly using the DPAK-3 (TO-252-3) SMD/SMT package format.

Applications

Motor control systems
Process control circuits
Temperature regulation devices

Procurement Notes

Verify the specific datasheet version and RoHS/REACH compliance status directly with Littelfuse or authorized distributors before integration. Confirm that the DPAK-3 footprint matches the target PCB design requirements. Ensure thermal management strategies account for the specified operating temperature limits during high-current operation.

Selection Notes

Select this component for medium-power applications requiring robust surface-mount SCR solutions. The 800V rating suits general industrial switching needs. Consider the 8A surge capability and 1.6V on-state drop for efficiency calculations. Verify compatibility with standard TO-252 footprints if replacing through-hole variants.

Part Context

This part belongs to the Low Power SCR series up to 1200V by Littelfuse. It serves as a silicon-controlled rectifier optimized for high-volume, cost-effective industrial and consumer electronics. The device provides reliable performance in environments demanding precise switching characteristics and wide operational temperature ranges.
