MCR100-8RLG

Scrs Overview

The MCR100-8RLG is a sensitive gate silicon controlled rectifier (SCR) from the MCR100 series, designed for high-volume line-powered consumer applications. It features a peak repetitive off-state voltage of 600 V and an on-state RMS current rating of 0.8 A at 80°C. The device supports a peak non-repetitive surge current of 10 A and includes specified minimum and maximum values for gate trigger current (IGT), gate trigger voltage (VGT), and holding current (IH). It operates within a junction temperature range of -40°C to +110°C and is supplied in a TO-92 (TO-226AA) package.

Scrs Feature Summary

• Sensitive gate architecture enables direct triggering by microcontrollers and logic circuits
• Glass-passivated surface construction ensures reliability and uniformity
• High surge current capability with specified dV/dt immunity

Scrs Applications

• Relay drivers
• Lamp drivers
• Small motor controls
• Gate drivers for larger thyristors
• Sensing and detection circuits

Scrs Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. The 'RL' designation indicates tape and reel shipping, while the 'G' suffix confirms lead-free compliance. Confirm the exact quantity per reel matches the manufacturer's standard specifications before procurement.

Scrs Selection Notes

Select this component when a 600 V blocking voltage and 0.8 A continuous current are required. Ensure the application circuit provides sufficient gate drive current below the 200 µA maximum threshold. Verify thermal management requirements align with the 75 °C/W junction-to-case thermal resistance for reliable operation.

Scrs Part Context

This part belongs to the MCR100 series of sensitive gate SCRs manufactured by onsemi. The series offers various voltage ratings including 100 V, 200 V, 400 V, and 600 V options. All variants share similar physical dimensions and electrical characteristics regarding current handling and gate sensitivity.

Scrs Replacement Considerations

Compatible replacements include other MCR100-8 variants such as MCR100-8 or MCR100-8G. Verify that substitute devices maintain the same TO-92 pinout configuration and meet the 600 V and 0.8 A electrical requirements.
