Overview
The Littelfuse S4N1RP is a silicon-controlled rectifier (SCR) belonging to the SxSx series, designed for sensing applications. It features a DO-214AB-2 surface-mount package and operates within a temperature range of -40°C to +110°C. Key electrical parameters include a rated repetitive off-state voltage (VDRM) of 400 V, an on-state RMS current (It RMS) of 800 mA, and a maximum holding current (Ih) of 5 mA. The device has a gate trigger voltage (Vgt) of 800 mV and a gate trigger current (Igt) of 50 uA. Additional specifications include a forward voltage (Vf) of 1.7 V, a non-repetitive peak on-state current of 20 A, and a maximum turn-on current (IBO) of 20 A.
Feature Summary
- Surface-mount construction in a compact DO-214AB-2 package suitable for automated assembly.
- Designed specifically for SCR sensing applications with defined gate triggering characteristics.
- Capable of handling high non-repetitive surge currents up to 20 A.
Applications
- SCR sensing circuits
- Industrial control systems requiring surface-mount thyristors
- Power control modules
Procurement Notes
Verify the specific Littelfuse datasheet for the S4N1RP to confirm all electrical ratings and mechanical dimensions before integration. Ensure that the selected component meets the required RoHS and REACH compliance standards for the target market. Cross-reference the manufacturer's official documentation to validate the part number against any recent product lifecycle changes or obsolescence notices.
Selection Notes
Select this component based on its 400 V blocking voltage and 800 mA RMS current capability. Consider the DO-214AB-2 package size for board space constraints. Verify that the gate trigger requirements align with the driving circuit's output capabilities. Ensure the operating temperature range covers the intended environmental conditions.
Part Context
The S4N1RP is part of Littelfuse's SxSx series of SCRs. This series focuses on providing reliable switching solutions in compact surface-mount packages. The S4N1RP specifically targets applications requiring moderate current handling and robust voltage blocking in a small form factor.
Replacement Considerations
Consult Littelfuse official documentation for verified replacement part numbers. Do not assume compatibility with other manufacturers' SCRs without verifying pinout, electrical ratings, and thermal characteristics.
