Overview
The Littelfuse S4010LS3 is a Silicon Controlled Rectifier (SCR) belonging to the Sxx10xSx series, designed for power control applications. It features a rated repetitive off-state voltage (VDRM) of 400 V and supports an RMS on-state current (It RMS) of 10 A. The device operates within a temperature range of -40°C to +110°C. Key electrical characteristics include a gate trigger voltage (Vgt) of 800 mV, a gate trigger current (Igt) of 500 uA, and a maximum holding current (Ih) of 8 mA. It utilizes a TO-220-2 package with a flange mount style, offering a non-repetitive peak on-state current capability of 100 A.
Feature Summary
- High sensitivity gate triggering requiring low current for reliable activation
- Robust thermal management via flange mount package design
- Low leakage current in the off-state for improved circuit efficiency
Applications
- AC power control circuits
- Lighting dimmer applications
- Motor speed control systems
Procurement Notes
Verify the specific suffix against official Littelfuse documentation to confirm pinout and packaging variations. Ensure the procurement channel provides valid RoHS compliance certificates. Confirm that the TO-220-2 package matches the thermal requirements of the target application before finalizing orders.
Selection Notes
Select this component when a 400 V blocking voltage and 10 A continuous current rating are required in a through-hole configuration. Compare the 500 uA gate trigger current against alternative SCRs if low-power drive signals are available. Verify that the TO-220-2 footprint fits the PCB layout constraints.
Part Context
This SCR is part of the Sxx10xSx family from Littelfuse, which standardizes 10 A devices across various voltage ratings. The S4010LS3 specifically addresses the 400 V segment, sharing common thermal and electrical characteristics with other members like the S4010NS3RP, but differing in package type and mounting style.
Replacement Considerations
Direct replacements must match the 400 V VDRM, 10 A It RMS, and TO-220-2 package. Check datasheets for equivalent gate trigger currents to ensure compatibility with existing drive circuits.
