MCR100-8-BP

Scrs Overview

The MCR100-8-BP is a Silicon Controlled Rectifier (SCR) manufactured by Micro Commercial Components. It features a peak repetitive forward and reverse blocking voltage of 600V and an RMS on-state current rating of 0.8A. The device operates within a junction temperature range of -40°C to +125°C and a storage temperature range of -55°C to +150°C. Electrical characteristics include a maximum gate trigger current of 80µA, a holding current of 5.0mA, and a forward 'on' voltage of 1.7V at 1A. The component utilizes a TO-92 package with straight or bent leads.

Scrs Feature Summary

• Epoxy material meets UL 94 V-0 flammability rating

Scrs Applications

• General purpose switching applications
• Relay and lamp drivers
• Small motor controls
• Gate drivers for larger thyristors
• Sensing and detection circuits

Scrs Procurement Notes

Verify the specific ordering suffix when sourcing this component. The '-BP' designation indicates bulk packaging, while '-AP' denotes ammo packing. Halogen-free variants require adding the '-HF' suffix to the part number. Purchase only from authorized distributors to ensure genuine parts with full traceability and compliance with MCC quality standards.

Scrs Selection Notes

Select the MCR100-8 variant specifically for circuits requiring a 600V blocking voltage; lower voltage ratings are available in the series. Ensure the application current does not exceed the 0.8A RMS limit. Consider the thermal management requirements given the operating junction temperature range up to +125°C. Verify that the low gate trigger current aligns with the driving logic capabilities.

Scrs Part Context

This component belongs to the MCR100 series of sensitive gate silicon controlled rectifiers designed for high-volume consumer applications. The series includes variants with different blocking voltages, such as the MCR100-6 rated at 400V. These devices are engineered for reliability in line-powered environments where general-purpose switching is required.

Scrs Replacement Considerations

Compatible replacements within the same family include the MCR100-6 for 400V applications. Other manufacturers produce equivalent SCR components with matching electrical parameters. Verify pinout compatibility and thermal resistance specifications before substituting.
