Overview
The Littelfuse S402BSRP is a Silicon Controlled Rectifier (SCR) belonging to the Sx02xS series, designed for surface mount applications. It features a rated repetitive off-state voltage (VDRM) of 400 V and an on-state current capacity of 1.5 A. The device exhibits a maximum off-state leakage current of 5 uA at VDRM. Packaged in a compact SOT-89-3 form factor, it supports both reel and cut tape mounting styles. This component serves as a thyristor solution for power control circuits requiring reliable switching performance in a small footprint.
Feature Summary
- Surface mount construction utilizing SOT-89-3 packaging for automated PCB assembly
- Rated for 400 V repetitive off-state voltage with low leakage characteristics
- Designed as a silicon controlled rectifier for general purpose power switching
Applications
- General purpose AC/DC power control circuits
- Industrial switching applications requiring surface mount thyristors
- Consumer electronics power regulation modules
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct package variant and tape/reel specifications. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Cross-reference the Littelfuse part number with authorized distributor catalogs to validate current availability and lead times. Ensure storage conditions align with semiconductor handling standards to prevent moisture sensitivity issues before reflow soldering.
Selection Notes
Select this component when a 400 V blocking capability and 1.5 A on-state current are required in a surface mount format. The SOT-89-3 package offers a space-saving alternative to through-hole equivalents. Evaluate thermal management requirements based on the specific duty cycle and ambient temperature conditions. Compare gate trigger characteristics against the driving circuit capabilities to ensure reliable turn-on performance within the target application constraints.
Part Context
The S402BSRP is part of the Littelfuse Sx02xS series of SCRs. This family provides silicon-controlled rectifiers optimized for surface mount technology. The components are categorized under thyristors and power semiconductors. Littelfuse manufactures these devices for industrial and consumer electronic markets. The series focuses on providing reliable power switching solutions in compact packages.
Replacement Considerations
Consult Littelfuse official substitution guides for compatible SCRs with matching voltage and current ratings. Verify pinout compatibility and thermal resistance values before replacing existing designs. Ensure any substitute component meets the same package dimensions and electrical specifications.
