Overview
The Littelfuse S4006VS2TP is a silicon-controlled rectifier (SCR) designed for high-reliability power control applications. It features a rated repetitive off-state voltage of 400 V and an RMS on-state current capability of 6 A. The device utilizes a sensitive gate architecture, requiring a maximum gate trigger current of 200 uA and a gate trigger voltage of 800 mV to initiate conduction. It operates within a temperature range of -40 C to +110 C and is housed in a TO-251 surface-mount package.
Feature Summary
- Sensitive gate structure enables reliable triggering with low input drive requirements
- High surge current handling capacity supports robust performance under transient conditions
- Surface-mount TO-251 package facilitates automated assembly and compact circuit board layouts
Applications
- Solid-state relays and contactor replacement circuits
- AC motor speed control and soft-start systems
- General-purpose AC power switching modules
Procurement Notes
Verify the specific suffix configuration against the manufacturer's latest datasheet to ensure compatibility with required thermal and electrical specifications. Confirm RoHS compliance status and packaging details directly with authorized distributors or the manufacturer before finalizing procurement orders.
Selection Notes
Select this component when a surface-mount SCR solution is required for moderate current applications. Ensure the circuit design accounts for the 400 V blocking voltage rating and verify that the gate drive circuitry can supply the necessary 200 uA trigger current reliably across the specified operating temperature range.
Part Context
This part belongs to the Sxx06xSx series of SCRs from Littelfuse. The series offers various voltage ratings while maintaining consistent current handling capabilities. The VS2TP designation indicates a specific voltage class and surface-mount packaging variant within this product family.
Replacement Considerations
Direct replacements include other 400 V, 6 A SCRs in TO-251 packages from Littelfuse or compatible manufacturers. Verify pinout compatibility and thermal resistance values when substituting.
