MCR8SNG

Overview

The MCR8SNG is a sensitive gate silicon controlled rectifier (SCR) from Littelfuse, rated for an 800 V peak repetitive off-state voltage and an 8.0 A RMS on-state current at 80°C case temperature. It features a high surge current capability of 80 A and operates within a junction temperature range of -40°C to 110°C. The device utilizes a TO-220AB package with glass passivated junctions for reliability. Key electrical characteristics include a maximum peak forward on-state voltage of 1.8 V, a gate trigger current of up to 200 µA, and a minimum dv/dt immunity of 5 V/µs at 110°C.

Feature Summary

Sensitive gate design enables direct triggering by microcontrollers and logic circuits
Glass passivated junctions provide durability and uniformity
High surge current capability supports demanding switching applications

Applications

Half-wave AC control applications
Motor controls
Heating controls
Power supplies

Procurement Notes

Verify the specific part number suffix against official Littelfuse documentation to confirm voltage ratings and packaging details. Ensure that thermal management requirements align with the specified junction-to-case thermal resistance values during integration. Confirm compliance with RoHS standards if required for the target assembly process.

Selection Notes

Select this component when half-wave SCR switching is required with sensitive gate drive capabilities. Consider the 800 V blocking voltage and 8 A RMS rating relative to the load requirements. Evaluate the TO-220AB package suitability for the available mounting space and heat dissipation constraints in the final design.

Part Context

The MCR8SNG belongs to the MCR8SDG, MCR8SMG, and MCR8SNG series of sensitive gate silicon controlled rectifiers. This family offers varying blocking voltage ratings from 400 V to 800 V while maintaining consistent on-state current and surge capabilities across the series.
