Overview
The MCR100-4RLRMG is a sensitive gate Silicon Controlled Rectifier (SCR) from the MCR100 series manufactured by onsemi. It features a reverse blocking PNPN structure housed in a plastic TO-92 (TO-226AA) package with straight leads supplied in an ammo pack configuration. The device supports a peak repetitive off-state voltage of 200 V and handles an RMS on-state current of 0.8 A at 80°C. Key electrical parameters include a maximum gate trigger current of 200 µA, a holding current up to 10 mA, and a surge current capability of 10 A.
Feature Summary
- Sensitive gate architecture enables reliable triggering using microcontrollers and standard logic circuits.
- Glass-passivated surface construction ensures uniformity and long-term reliability.
- High dV/dt immunity provides protection against false triggering during rapid voltage transients.
Applications
- Relay and lamp driver circuits
- Small motor control systems
- Gate drivers for larger thyristors
- Sensing and detection circuits
Procurement Notes
Verify the specific ordering suffix RLRMG to confirm the straight lead style and ammo pack packaging format. Ensure the component meets Pb-Free requirements if mandated by project specifications. Confirm that the 200 V blocking voltage rating aligns with the circuit's peak operating conditions before finalizing procurement.
Selection Notes
Select this device when a low-cost SCR with sensitive gate characteristics is required for line-powered consumer applications. The 200 V rating suits moderate voltage environments, while the 0.8 A RMS current capacity fits small load switching tasks. Verify thermal management needs as the junction-to-ambient resistance is relatively high compared to higher-power packages.
Part Context
This part belongs to the MCR100 series of reverse blocking thyristors designed for high-volume consumer electronics. The series offers various voltage ratings ranging from 100 V to 600 V, allowing designers to choose appropriate blocking capabilities for different line voltages while maintaining consistent package dimensions and triggering characteristics across the family.
Replacement Considerations
Compatible substitutes within the same series include MCR100-3RLRMG (100 V), MCR100-6RLRMG (400 V), and MCR100-8RLRMG (600 V). When replacing, ensure the new part's voltage rating exceeds the circuit's peak reverse voltage. Other manufacturers' TO-92 SCRs may be compatible if their IGT and IT(RMS) specifications match or exceed these values.
