Overview
The MCR22-2RL1 is a silicon-controlled rectifier (SCR) manufactured by onsemi. It features a maximum repetitive peak off-state voltage of 50 V and a maximum average on-state current of 1.5 A. The device utilizes a TO-92 (TO-226) three-lead package designed for through-hole mounting. This component is supplied in tape and reel packaging, facilitating automated assembly processes.
Feature Summary
- Utilizes a compact TO-92 (TO-226) leaded package suitable for space-constrained applications.
- Engineered with a silicon-controlled rectifier structure for reliable switching performance.
- Designed for high-volume manufacturing via standard tape and reel supply configuration.
Applications
- Low-voltage DC power control circuits
- General-purpose switching applications
- Consumer electronics protection circuits
Procurement Notes
Verify the specific suffix 'RL1' to confirm the tape and reel packaging format required for automated surface-mount or insertion machines. Ensure the procurement order matches the exact manufacturer part number to avoid receiving bulk tube variants that may require manual handling. Confirm the 50V rating aligns with the target circuit's voltage requirements before finalizing the purchase order.
Selection Notes
Select this component when a low-cost, general-purpose SCR is needed for currents up to 1.5 A. The TO-92 package offers a balance of thermal dissipation and physical size for small form-factor designs. Consider the 50V voltage limit carefully; higher voltage applications require alternative part numbers from the same family with increased blocking capabilities.
Part Context
This device belongs to the broader category of discrete semiconductor switches produced by onsemi. It serves as a fundamental building block for controlling electrical flow in low-power systems. The product line focuses on providing robust, cost-effective solutions for mass-market electronic devices requiring simple, reliable switching functionality.
Replacement Considerations
Direct substitutes include other 50V, 1.5A SCRs in the TO-92 package from compatible manufacturers. Verify pinout compatibility and thermal characteristics when cross-referencing equivalent components from different suppliers to ensure seamless integration into existing PCB layouts.
