Overview
The S4006LS3TP is a silicon-controlled rectifier (SCR) manufactured by Littelfuse Inc. It features a rated repetitive peak off-state voltage of 400 V and an on-state RMS current of 6 A. The device utilizes a sensitive gate structure with a maximum DC gate trigger current of 200 µA and a maximum gate trigger voltage of 800 mV. It is housed in a TO-252AA (DPAK) surface-mount package with the case connected to the anode. The component operates within a junction temperature range of -40 °C to +125 °C.
Feature Summary
- Sensitive gate triggering capability for low-power control applications
- Surface-mount DPAK packaging with anode-connected tab for thermal management
- High surge current handling capacity for robust circuit protection
Applications
- AC power switching circuits
- Solid-state relays
- Motor speed control systems
Procurement Notes
Verify the specific suffix 'TP' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging configuration and pinout orientation. Ensure the selected variant matches the required thermal resistance and mounting specifications for the target PCB layout. Cross-reference the part number with Littelfuse documentation to validate compliance with RoHS directives and REACH SVHC requirements before finalizing procurement orders.
Selection Notes
Select this component when a surface-mount SCR with sensitive gate drive is required for compact designs. The 6 A RMS rating suits moderate power loads, while the 400 V blocking voltage provides adequate headroom for standard AC line applications. Consider the TO-252AA package constraints for heat dissipation and ensure the gate trigger parameters align with the driving logic levels available in the system architecture.
Part Context
This device belongs to the Littelfuse Sxx06xSx series of thyristors, designed for general-purpose power control. The S4006LS3TP specifically offers a balance of high current density and low gate sensitivity in a surface-mount form factor. It serves as a modern alternative to through-hole SCRs in space-constrained industrial and consumer electronics where reliable AC switching is essential.
Replacement Considerations
Direct replacements include the S4006DS2TP from Littelfuse, which shares identical electrical ratings and package type. Verify that any substitute maintains the same sensitive gate characteristics and thermal performance metrics to ensure circuit compatibility without redesign.
