Overview
The Littelfuse S6S3RP is a silicon-controlled rectifier (SCR) from the SxSx series, designed for sensing applications in surface-mount technology. It features a DO-214AB-2 package with a rated repetitive off-state voltage of 600 V and an RMS on-state current of 800 mA. The device has a maximum gate trigger voltage of 800 mV and a gate trigger current of 50 µA. It operates within a temperature range of -40 °C to +110 °C, with a non-repetitive peak on-state current of 20 A and a holding current maximum of 5 mA.
Feature Summary
- Surface-mount construction for automated PCB assembly
- Low gate trigger current for sensitive control circuits
- High surge current capability for transient protection
Applications
- AC power switching controls
- Lighting dimmer circuits
- Motor speed control systems
Procurement Notes
Verify the specific datasheet revision and RoHS compliance status directly with Littelfuse or authorized distributors before procurement. Confirm that the DO-214AB-2 footprint matches the target PCB design. Ensure storage conditions adhere to moisture sensitivity levels specified in the official documentation to prevent soldering defects during reflow processes.
Selection Notes
Select the S6S3RP when a 600 V blocking voltage and 800 mA continuous current rating are required in a compact surface-mount form factor. Compare the 50 µA gate trigger current against circuit drive capabilities to ensure reliable turn-on. Evaluate thermal management requirements based on the 110 °C maximum junction temperature limit and the specific ambient operating conditions of the final application.
Part Context
The S6S3RP belongs to the Littelfuse SxSx family of SCRs, which are optimized for sensing and general-purpose switching. This series provides various voltage and current ratings in standardized surface-mount packages to facilitate design flexibility. The component serves as a robust alternative to through-hole thyristors in space-constrained consumer and industrial electronics.
Replacement Considerations
Direct pin-compatible replacements within the same package may include other SxSx series variants with matching voltage and current ratings. Verify equivalent gate characteristics and thermal performance before substituting. Cross-reference with Littelfuse's official substitution guide for confirmed compatible parts.
