Overview
The MCR22-8G is a sensitive gate Silicon Controlled Rectifier (SCR) manufactured by onsemi, designed for applications requiring low gate drive current. It features a rated repetitive off-state voltage of 600 V and an RMS on-state current capability of 1.5 A. The device operates within a junction temperature range of -40°C to +110°C and is housed in 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 forward voltage drop of 1.7 V at rated current.
Feature Summary
- Sensitive gate architecture enables reliable triggering with minimal gate current requirements.
- Reverse blocking thyristor structure provides robust performance in AC control circuits.
- Low on-state voltage characteristic contributes to improved thermal efficiency.
Applications
- Small motor control systems
- Gate driver circuits for larger SCRs
- Sensing and detecting circuits
Procurement Notes
Verify the specific suffix 'G' against official datasheets to confirm RoHS compliance status, as packaging and environmental declarations can vary. Confirm availability status directly with authorized distributors, as lead times and stock levels fluctuate. Ensure the TO-92-3 package dimensions match your PCB footprint requirements before finalizing procurement decisions.
Selection Notes
Select this component when a compact, through-hole SCR is needed for low-power AC switching or sensing applications. The sensitive gate feature makes it suitable for microcontroller-driven interfaces where output current is limited. Verify that the 600 V voltage rating exceeds the peak line voltage in your specific application environment to ensure adequate safety margins.
Part Context
This part belongs to the MCR22 series of sensitive gate silicon controlled rectifiers from onsemi. These devices are engineered primarily for half-wave AC control applications. The series is characterized by its ability to operate effectively in environments with limited gate drive capability, distinguishing it from standard gate thyristors.
Replacement Considerations
Cross-reference with other manufacturers' MCR22-8 equivalents, such as those from Central Semiconductor, ensuring voltage and current ratings align. Verify pinout compatibility and thermal characteristics before substituting to maintain circuit integrity.
