Overview
The onsemi MCR22-6G is a silicon-controlled rectifier (SCR) designed for general-purpose switching applications. It features a single-phase configuration housed in a TO-92 surface-mount package. The device supports a maximum repetitive peak off-state voltage of 400V and an RMS on-state current of 1.5A. Key electrical characteristics include a gate trigger voltage of 0.8V maximum, a holding current of 5mA maximum, and a non-repetitive peak on-state current of 15A. It operates within a temperature range of -40°C to +125°C.
Feature Summary
- Provides robust overcurrent protection through high surge current handling capability
- Offers reliable latching behavior with low gate trigger requirements for efficient control
- Ensures stable performance across wide industrial temperature extremes
Applications
- General purpose AC/DC switching circuits
- Overvoltage and overcurrent protection modules
- Lighting control systems requiring compact form factors
Procurement Notes
Verify the specific suffix 'G' indicates lead-free compliance against the manufacturer's latest datasheet. Confirm the package variant matches the required TO-92 SMD footprint dimensions. Ensure the ordering information aligns with the current production status and availability from authorized distributors.
Selection Notes
Select this component when a compact, surface-mount SCR is required for moderate current switching tasks. Evaluate the 1.5A RMS rating against continuous load requirements and the 15A surge capacity against transient events. Consider the TO-92 package constraints for thermal management and board space limitations compared to larger through-hole alternatives.
Part Context
This part belongs to the MCR22 series of silicon-controlled rectifiers manufactured by onsemi. The series is characterized by its versatility in small-signal power control applications. The MCR22-6G specifically denotes the lead-free version of the standard MCR22-6 device, maintaining identical electrical specifications while adhering to environmental compliance standards.
Replacement Considerations
Direct replacements include the Central Semiconductor MCR22-6 and other generic MCR22-6 variants. Verify pinout compatibility and ensure the substitute meets the same 400V voltage and 1.5A current ratings. Check for equivalent thermal resistance and package tolerance differences.
