Sensitive gate design enabling low gate triggering current requirements
High reliability construction suitable for operation in harsh environments

Scrs Applications

Industrial control systems requiring sensitive gate triggering
Power management circuits optimized for reduced power losses
Harsh environment applications demanding high reliability

Scrs Procurement Notes

Verify the specific ordering suffix and package variant against official STMicroelectronics documentation before procurement. Confirm that the 600 V rating aligns with circuit requirements. Ensure compatibility with through-hole assembly processes. Cross-reference the active production status and lead times directly with authorized distributors to avoid obsolescence risks.

Scrs Selection Notes

Select this component when a 1.25 A SCR with sensitive gate characteristics is required. The 600 V blocking voltage suits medium-voltage applications. Consider the TO-92 package constraints for thermal management. Verify that the 200 µA gate trigger current matches the driving circuit capabilities. Evaluate the -40°C to +125°C operating range against environmental conditions.
