Overview
The Littelfuse S4004VS2TP is a silicon-controlled rectifier (SCR) designed for surface-mount applications. It features a rated repetitive off-state voltage of 400 V and an RMS on-state current capability of 4 A. The device operates within a temperature range of -40°C to +110°C and utilizes a DPAK-2 (TO-252-2) package. Key electrical characteristics include a gate trigger current of 200 uA, a forward voltage of 1.6 V, and a maximum holding current of 6 mA.
Feature Summary
- Surface-mount construction in a compact DPAK-2 package for automated assembly
- Sensitive gate triggering with low required gate current for efficient control
- Robust thermal performance supporting operation up to 110°C junction temperature
Applications
- Solid-state relay input stages
- Industrial motor control circuits
- Power supply switching regulation
Procurement Notes
Verify the specific suffix 'S2TP' against official Littelfuse documentation to confirm the exact pinout configuration and packaging variant. Ensure the selected component matches the required DPAK-2 footprint and thermal dissipation capabilities for the target application environment before finalizing procurement.
Selection Notes
Select this SCR when a surface-mount solution is required for moderate current switching applications. The 400V rating suits low-voltage AC/DC control systems. Consider the 200uA gate sensitivity for compatibility with low-power logic drivers. Verify that the DPAK-2 package provides adequate heat sinking for the expected RMS current load.
Part Context
This component belongs to the Sxx04xSx series of thyristors from Littelfuse. The series is engineered for general-purpose power switching tasks. The S4004VS2TP specifically addresses the need for reliable, space-efficient control elements in modern electronic designs requiring robust semiconductor switching capabilities.
Replacement Considerations
Consult Littelfuse cross-reference guides for verified substitutes. Ensure any replacement maintains the 400V voltage rating, 4A current capacity, and compatible DPAK-2 package dimensions to preserve circuit board layout integrity.
