Overview
The MCR100-8RL is a reverse blocking thyristor from the MCR100 series manufactured by onsemi. It features a sensitive gate design and is housed in a TO-92 (TO-226AA) plastic package. The device supports a peak repetitive off-state voltage of 600 V and an on-state RMS current rating of 0.8 A at 80°C. It provides a high surge current capability of 10 A and includes glass-passivated surfaces for reliability. Electrical characteristics specify a maximum gate trigger current of 200 µA, a holding current of up to 10 mA, and a minimum dV/dt immunity of 20 V/µs at 110°C.
Feature Summary
- Sensitive gate architecture enables direct triggering by microcontrollers and logic circuits
- Glass-passivated surface construction ensures uniformity and operational reliability
- Robust surge handling with 10 A non-repetitive peak current capability
- High dV/dt immunity minimizes false triggering during rapid voltage transitions
Applications
- Relay and lamp drivers in line-powered consumer electronics
- Small motor control circuits
- Gate drivers for larger thyristors
- Sensing and detection circuits
Procurement Notes
Verify the specific ordering suffix to confirm packaging configuration. The RL suffix indicates availability in tape and reel format, which facilitates automatic insertion equipment usage. Confirm RoHS compliance status through official documentation before procurement. Ensure the selected variant matches the required voltage rating for the target application circuit.
Selection Notes
Select this component when a low-cost, sensitive-gate SCR is required for AC control applications. The 600 V rating suits standard line-voltage environments. Verify that the 0.8 A RMS current capacity meets the load requirements. Consider thermal derating curves if operating near maximum case temperatures. Ensure the gate drive circuit can supply sufficient current within the specified trigger limits.
Part Context
This device belongs to the MCR100 series of Silicon Controlled Rectifiers designed for high-volume consumer applications. The series offers various voltage ratings ranging from 100 V to 600 V. All variants share similar physical dimensions and electrical characteristics, differing primarily in their blocking voltage capabilities and specific ordering codes.
Replacement Considerations
Direct replacements must match the TO-92 package, 600 V blocking voltage, and 0.8 A RMS current rating. Verify that substitute devices offer comparable sensitive gate sensitivity and dV/dt immunity. Cross-reference pin assignments to ensure Gate, Anode, and Cathode configurations align.
