Overview
The MCR22-6 is a silicon-controlled rectifier (SCR) manufactured by Central Semiconductor Corp. It features a maximum repetitive off-state voltage of 400 V and an RMS on-state current rating 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 gate trigger voltage of 800 mV, a gate trigger current of 200 µA, and a forward voltage drop of 1.7 V at rated current. The component exhibits a non-repetitive peak on-state current capability of 15 A and maintains a holding current maximum of 5 mA.
Feature Summary
- High-voltage blocking capability suitable for AC control applications
- Robust surge current handling with 15 A non-repetitive peak rating
- Low gate trigger requirements for efficient drive circuitry
Applications
- Lighting dimmer circuits
- Solid-state relays
- Motor speed control systems
Procurement Notes
Verify the specific suffix designation when ordering, as availability may vary between leaded and lead-free variants. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to procurement. Ensure that the selected packaging format matches the assembly requirements, as bulk and tape-and-reel options may exist for this component family.
Selection Notes
Select this component for low-power AC switching tasks requiring moderate voltage isolation. Evaluate thermal management needs based on the 1.5 A RMS rating and TO-92-3 package constraints. Compare gate sensitivity parameters against available driver outputs to ensure reliable triggering under varying temperature conditions.
Part Context
This SCR belongs to the MCR22 series of small-signal thyristors designed for general-purpose switching. The TO-92-3 form factor allows for compact integration into consumer electronics and industrial control boards where space is limited but robust latching behavior is required for load management.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical ratings before considering alternative manufacturers.
