Overview
The S4006VS2 is a silicon-controlled rectifier (SCR) manufactured by Littelfuse Inc., designed for through-hole mounting in the TO-220 package with an isolated tab. It features a rated repetitive off-state voltage of 400 V and an RMS on-state current of 6 A. The device has a maximum gate trigger current of 200 µA and a gate trigger voltage of 800 mV. It operates within a temperature range of -40°C to +110°C, with a maximum holding current of 6 mA and a forward voltage drop of 1.6 V.
Feature Summary
- Sensitive gate triggering capability for low-power control applications
- Isolated tab construction for efficient thermal management and electrical isolation
- Robust performance in high-voltage switching environments
Applications
- AC power control circuits
- Motor speed control systems
- Lighting dimmer applications
Procurement Notes
Verify the specific suffix against manufacturer documentation to confirm pinout and isolation characteristics. Ensure the procurement channel provides original Littelfuse components to guarantee compliance with RoHS standards and operational reliability in critical electronic assemblies.
Selection Notes
Select this component when a 400 V blocking voltage and 6 A continuous current capacity are required in a standard TO-220 isolated package. Consider the 200 µA gate sensitivity for compatibility with low-current drive signals and verify thermal dissipation requirements for the intended operating environment.
Part Context
This SCR belongs to the Sxx06xSx series from Littelfuse, which offers various voltage ratings within the same current and package family. The S4006VS2 specifically addresses applications requiring 400 V blocking capability while maintaining the compact form factor and sensitive gate drive characteristics typical of this product line.
Replacement Considerations
The S4006LS2TP is documented as a parameter-equivalent substitute. Verify that the alternative package and thermal characteristics align with the existing board design before implementation.
