MCR12NG

Overview

The Littelfuse MCR12NG is a Silicon Controlled Rectifier (SCR) rated for a peak repetitive off-state voltage of 800V. It supports an on-state RMS current of 12A at 80°C and handles a peak non-repetitive surge current of 100A. The device features glass passivated junctions, high dv/dt immunity of 100 V/µs minimum at 125°C, and operates within a junction temperature range of -40 to +125°C. Packaged in a TO-220AB case, it is designed for half-wave AC control applications.

Feature Summary

Glass passivated junctions ensure reliability and uniformity
High immunity to dv/dt with a minimum rating of 100 V/µs at 125°C
Specified minimum and maximum values for gate trigger current, gate trigger voltage, and holding current

Applications

Half-wave AC motor controls
Heating controls
Power supplies

Procurement Notes

Verify the specific part number suffix against official Littelfuse documentation to confirm voltage ratings and package details. Ensure compatibility with thermal management requirements for the TO-220AB package. Confirm RoHS compliance status through manufacturer datasheets before procurement.

Selection Notes

Select the MCR12NG when an 800V blocking voltage is required alongside a 12A RMS current capacity. Consider the specified gate trigger parameters for driver circuit design. Evaluate thermal resistance characteristics for heat sink sizing in continuous operation scenarios.

Part Context

The MCR12NG belongs to the MCR12DG, MCR12MG, and MCR12NG family of silicon controlled rectifiers from Littelfuse. This series shares common electrical characteristics and packaging but varies primarily in peak repetitive off-state voltage ratings, offering options for 400V, 600V, and 800V applications.

Replacement Considerations

MCR12MG serves as a lower voltage alternative within the same series. Verify pinout compatibility and thermal performance when substituting with other SCR manufacturers' components.
