Overview
The MCR22-008 is a sensitive gate Silicon Controlled Rectifier (SCR) manufactured by onsemi. It features a rated repetitive peak off-state voltage of 600 V and an RMS on-state current capability of 1.5 A. The device operates within a temperature range of -40°C to +110°C and is housed in a TO-92-3 through-hole package. Key electrical parameters include a maximum holding current of 5 mA, a gate trigger voltage of 800 mV, and a gate trigger current of 200 µA. The component exhibits a forward voltage drop of 1.7 V at rated current.
Feature Summary
- Sensitive gate triggering architecture designed for applications with limited gate current availability.
- Robust thyristor construction providing reliable switching performance in small motor control and sensing circuits.
Applications
- Small motor control systems
- Gate driver circuits for larger SCRs
- Sensing and detecting circuits
Procurement Notes
Verify the specific suffix designation against official datasheets, as variations exist between MCR22-8 and MCR22-8RL1G. Confirm RoHS compliance status and lead-free specifications directly from the manufacturer's documentation before integration. Ensure the procurement channel provides valid traceability for this discontinued or restricted component type.
Selection Notes
Select this component when a low-gate-current SCR is required for 600 V blocking applications. The TO-92 package suits space-constrained through-hole designs. Verify that the 1.5 A RMS current rating meets the load requirements and that the sensitive gate characteristics align with the driving circuit's output capabilities.
Part Context
This part belongs to the MCR22 series of sensitive gate silicon controlled rectifiers. The series is characterized by low gate trigger requirements, making it suitable for interfacing with logic-level drivers or high-impedance sensors. The MCR22-8 variant specifically targets 600 V applications, distinguishing it from lower voltage counterparts like the MCR22-6.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Cross-reference with other manufacturers' sensitive gate SCRs only if electrical parameters match exactly.
