Overview
The S4006NS2TP is a silicon-controlled rectifier (SCR) manufactured by Littelfuse, designed for high-reliability power control applications. It features a rated repetitive off-state voltage (VDRM) of 400 V and an on-state RMS current (It RMS) of 6 A. The device operates within a temperature range of -40°C to +110°C and utilizes a D2PAK-3 (TO-263-3) surface-mount package. Key electrical characteristics include a maximum gate trigger voltage (Vgt) of 800 mV, a gate trigger current (Igt) of 200 µA, and a forward voltage drop (Vf) of 1.6 V at rated current. The component exhibits a low holding current of 6 mA maximum and supports non-repetitive surge currents up to 100 A.
Feature Summary
- Sensitive gate architecture enabling reliable triggering with minimal gate drive current requirements
- Surface-mount TO-263-3 packaging optimized for automated assembly and compact PCB layouts
- Robust thermal performance supporting operation in elevated ambient temperature environments
Applications
- Solid-state relay input stages requiring isolated switching control
- Industrial motor control circuits for AC power regulation
- General-purpose AC power switching and phase control systems
Procurement Notes
Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status and REACH SVHC declarations prior to integration into regulated supply chains. Ensure that the selected distributor provides traceable documentation matching the Littelfuse part number to avoid counterfeit components.
Selection Notes
Select this component when a 400 V blocking capability and 6 A continuous current rating are required in a surface-mount form factor. Compare the sensitive gate specifications against alternative packages such as TO-252 or TO-220 if through-hole mounting is preferred. Evaluate thermal dissipation requirements based on the D2PAK-3 footprint and expected duty cycle in the target application circuit.
Part Context
This device belongs to the Littelfuse Sxx06xSx series of silicon-controlled rectifiers. The series offers various voltage ratings and package options to suit different power density needs. The S4006NS2TP specifically addresses the need for compact, high-current SCR solutions in modern electronics where space constraints limit the use of traditional through-hole thyristors.
Replacement Considerations
Direct substitutes include other Littelfuse SCRs with identical 400 V/6 A ratings in compatible packages, such as the S4006DS2TP (TO-252-2). Verify pinout alignment and thermal resistance values before substituting with devices from other manufacturers.
