Overview
The MCR22-2RL1G is a Silicon Controlled Rectifier (SCR) manufactured by onsemi, belonging to the MCR22-2 series. It features a rated repetitive off-state voltage of 200 V and an RMS on-state current capability of 1.5 A. The device operates within a junction temperature range of -40°C to +125°C and utilizes a TO-92-3 through-hole package. Key electrical characteristics include a maximum holding current of 5 mA, a gate trigger voltage of 800 mV, and a gate trigger current of 200 uA. The component exhibits a forward voltage drop of 1.7 V and supports non-repetitive peak on-state currents up to 15 A.
Feature Summary
- Provides reliable phase control functionality for AC power regulation circuits
- Features low gate trigger requirements for efficient driver interface compatibility
- Offers robust thermal performance suitable for high-temperature industrial environments
Applications
- Lighting dimmer circuits
- Motor speed control systems
- Temperature control regulators
Procurement Notes
Verify the specific suffix RL1G against official onsemi documentation to confirm lead-free status and reel packaging specifications. Confirm availability as distribution channels may vary. Ensure compliance with RoHS directives if required by the target application. Validate that the TO-92-3 package dimensions match the PCB footprint design constraints before finalizing procurement.
Selection Notes
Select this component when a 200 V blocking voltage and 1.5 A continuous current rating are required in a compact through-hole form factor. Consider the 800 mV gate trigger threshold for logic-level driving compatibility. Evaluate the thermal dissipation capabilities within the TO-92-3 package against the expected load duty cycle and ambient operating conditions.
Part Context
This SCR belongs to the MCR22 family of general-purpose thyristors designed for medium-power applications. The MCR22-2 variant specifically targets lower voltage AC control scenarios compared to higher voltage siblings like the MCR22-6 or MCR22-8. The RL1G suffix typically denotes tape-and-reel packaging for automated assembly processes.
Replacement Considerations
Direct replacements include other MCR22-2 variants from different manufacturers such as Central Semiconductor's MCR22-2 APP PBFREE, provided pinout and electrical ratings align. Verify equivalent gate sensitivity and holding current specifications when substituting.
