Scrs datasheet and documents for MCR8NG

MCR8NG

Scrs Overview

The Littelfuse MCR8NG is a silicon-controlled rectifier (SCR) housed in a TO-220AB package. It features a peak repetitive off-state voltage of 800 V and an on-state RMS current rating of 8.0 A at a case temperature of 80°C. The device supports a peak non-repetitive surge current of 80 A and offers high immunity to dv/dt with a minimum rating of 100 V/µs at 125°C. Electrical characteristics include a gate trigger current range of 2.0 mA to 15 mA, a holding current maximum of 30 mA, and a peak on-state voltage of 1.8 V at 16 A. Thermal resistance from junction to case is 2.2 °C/W.

Scrs Feature Summary

Glass passivated junctions for reliability and uniformity
Specified minimum and maximum values for gate trigger current, gate trigger voltage, and holding current
High immunity to dv/dt ensuring stable operation under rapid voltage changes

Scrs Applications

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

Scrs Procurement Notes

Verify the specific part number against official Littelfuse documentation to confirm the 800V blocking voltage rating associated with the NG suffix. Ensure that thermal management strategies account for the specified junction-to-case thermal resistance and operating temperature limits during installation.

Scrs Selection Notes

Select this component when designing circuits requiring half-wave SCR control with an 800V blocking capability. Consider the 8A RMS current rating relative to the expected load and ambient temperature derating curves. Verify that the gate drive circuitry can supply sufficient current within the specified 2.0 mA to 15 mA trigger range.

Scrs Part Context

The MCR8NG belongs to the Littelfuse Silicon Controlled Rectifiers series designed for 600V to 800V applications. It utilizes a rugged TO-220AB package suitable for through-hole mounting. The device is lead-free compliant and intended for general-purpose switching tasks where reliable half-wave control is required.
