MCR100-6RL

Scrs Overview

The MCR100-6RL is a sensitive gate silicon controlled rectifier (SCR) from the MCR100 series, manufactured by onsemi. It features a peak repetitive off-state voltage of 400 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 utilizes a TO-92 (TO-226AA) plastic package with three leads: Gate, Anode, and Cathode.

Scrs Feature Summary

• Sensitive gate architecture enables direct triggering by microcontrollers and logic circuits
• Glass-passivated surface provides reliability and uniformity
• High dV/dt immunity ensures stable operation in noisy environments

Scrs Applications

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

Scrs Procurement Notes

Verify the exact ordering suffix to confirm packaging configuration. The RL suffix indicates a tape and reel format containing 2000 units per reel. Confirm lead finish and RoHS compliance status through official manufacturer documentation before procurement.

Scrs Selection Notes

Select this component when a low-cost, high-volume SCR is required for line-powered consumer applications. Ensure the circuit design accommodates the 400 V blocking voltage and 0.8 A RMS current limits. Verify that the sensitive gate characteristics align with the available drive voltage and current from the control logic.

Scrs Part Context

This part belongs to the MCR100 series of reverse-blocking thyristors designed for high-volume production. The series offers various voltage ratings ranging from 100 V to 600 V, allowing designers to choose the appropriate blocking voltage while maintaining consistent package dimensions and electrical interface characteristics across the family.

Scrs Replacement Considerations

Compatible replacements within the same series include MCR100-3RL, MCR100-4RL, and MCR100-8RL, which share identical pinouts and packages but differ in blocking voltage ratings. Cross-manufacturer equivalents should be verified against specific electrical parameters such as IGT, VGT, and thermal resistance.
