Overview
The Littelfuse S402BS1RP is a silicon-controlled rectifier (SCR) from the Sx02xS series, designed for surface-mount applications in the SOT-89-3 package. It features a rated repetitive off-state voltage (VDRM) of 400 V and an on-state RMS current (It RMS) of 1.5 A. The device exhibits a maximum off-state leakage current of 5 uA at VDRM. Operating within a temperature range of -40 C to +125 C, this component serves as a sensitive gate thyristor suitable for compact circuit designs requiring reliable switching capabilities.
Feature Summary
- Surface-mount construction utilizing the SOT-89-3 package for automated assembly integration
- Sensitive gate architecture enabling reliable triggering with low control power requirements
- High thermal stability supporting operation up to +125 C junction temperature
Applications
- General purpose AC/DC power control circuits
- Solid-state relay driver stages
- Lighting dimmer control modules
Procurement Notes
Verify the specific ordering suffix against the manufacturer datasheet to ensure correct packaging configuration. Confirm that the SOT-89-3 footprint matches the target PCB layout. Check for RoHS compliance status and REACH SVHC declarations prior to final procurement approval.
Selection Notes
Select this component when a compact surface-mount SCR is required for moderate current switching. Ensure the circuit design accommodates the 400 V blocking capability and 1.5 A continuous load rating. Verify that the sensitive gate characteristic aligns with the available trigger drive signal levels in the application.
Part Context
This part belongs to the Littelfuse Sx02xS family of thyristors. The series offers various voltage and current ratings packaged in standard forms. The S402BS1RP specifically addresses the need for small-footprint, high-voltage switching in consumer and industrial electronics where board space is limited.
Replacement Considerations
Consult official substitution guides for equivalent SCRs in the SOT-89-3 package. Verify matching electrical parameters including VDRM, It RMS, and gate sensitivity before implementing any alternative components.
