Overview
The MCR100-3RLG is a sensitive gate silicon controlled rectifier (SCR) from the ON Semiconductor MCR100 series, designed for high-volume line-powered consumer applications. It features a peak repetitive off-state voltage of 100 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, gate trigger voltage, and holding current to facilitate design integration. Packaged in a plastic TO-226AA (TO-92) format with tape-and-reel shipping, it offers dV/dt immunity of 20 V/µs minimum at 110°C.
Feature Summary
- Sensitive gate architecture enables direct triggering by microcontrollers and standard logic circuits
- Glass-passivated surface construction ensures reliability and uniformity across operating conditions
- Specified minimum and maximum electrical parameters simplify circuit design and component selection
Applications
- Relay drivers
- Lamp drivers
- Small motor controls
- Gate drivers for larger thyristors
- Sensing and detection circuits
Procurement Notes
Verify that the ordering suffix RLG corresponds to the specific 2000-unit tape and reel packaging configuration. Confirm the Pb-Free status aligns with project requirements. Ensure the 100 V blocking voltage rating meets the system's peak repetitive off-state voltage demands. Validate that the TO-226AA package dimensions are compatible with the intended automatic insertion equipment or PCB layout constraints.
Selection Notes
Select this component when a low-cost SCR with sensitive gate characteristics is required for line-powered applications. The 100 V rating suits lower voltage AC control scenarios compared to higher voltage variants in the series. Consider the 0.8 A RMS current limit for load management. The specified gate trigger parameters allow for direct interfacing with digital logic without additional amplification stages.
Part Context
This part belongs to the MCR100 series of reverse blocking thyristors manufactured by ON Semiconductor. The series covers blocking voltages ranging from 100 V to 600 V, with the MCR100-3 variant specifically rated for 100 V. The 'RLG' suffix indicates a lead-free version supplied in a tape and reel format, distinguishing it from bulk box or ammo pack configurations available within the same product family.
Replacement Considerations
Compatible substitutes include other MCR100-3 variants such as MCR100-3G (Pb-Free bulk) or MCR100-3 (bulk). Cross-manufacturer equivalents should be verified against the 100 V blocking voltage, 0.8 A RMS current, and TO-92 pinout compatibility.
