Overview
The S201ERP is a Silicon Controlled Rectifier (SCR) manufactured by Littelfuse Inc. It features a standard recovery characteristic and is housed in a TO-92 package, specifically identified as TO-226AA or TO-92-3 with formed leads. The device supports an operating temperature range from -40°C to 125°C. Key electrical specifications include a maximum repetitive peak off-state voltage of 200V and a maximum on-state current rating of 1A. The component utilizes a gate trigger mechanism with a maximum gate trigger voltage of 1.5V.
Feature Summary
- Standard recovery performance for reliable switching operations
- Robust thermal management capability across wide temperature extremes
- Compact through-hole packaging suitable for dense circuit layouts
Applications
- Embedded electronics control circuits
- Industrial equipment power regulation
- OEM production systems requiring compact thyristors
Procurement Notes
Verify the specific suffix 'ERP' against official Littelfuse documentation to confirm exact pin configuration and mechanical tolerances. Ensure the receiving facility accepts the TO-92/TO-226AA form factor. Cross-reference the 200V/1A ratings with the actual circuit requirements to prevent over-stress conditions during procurement validation.
Selection Notes
Select this component when a low-voltage, high-current SCR is required in a small footprint. The 200V rating limits suitability to low-power applications. Consider the TO-92 package constraints for thermal dissipation needs. Verify that the 1A current capacity aligns with the load profile before finalizing the design choice.
Part Context
This part belongs to the Littelfuse discrete semiconductor product line, specifically within the Thyristors - SCRs category. It serves as a fundamental switching element for AC and DC control applications. The manufacturer provides this component as part of their broader portfolio of circuit protection and power control solutions designed for various electronic industries.
Replacement Considerations
Consult official Littelfuse substitution guides for verified equivalents. Generic replacements may differ in gate trigger characteristics or thermal resistance. Ensure any substitute maintains the TO-92 package dimensions and 200V/1A electrical ratings to guarantee compatibility.
