Overview
The Littelfuse S4006RS2 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 µA and a gate trigger voltage of 800 mV to initiate conduction. It operates within a junction temperature range of -40°C to +110°C and is housed in a TO-220AB package with an isolated tab for mounting.
Feature Summary
- Sensitive gate structure enabling reliable triggering with low input current
- Isolated tab design facilitating secure thermal management and electrical isolation from heatsinks
- Robust construction supporting high surge current handling capabilities
Applications
- Industrial motor speed control systems
- Solid-state relay output stages
- General purpose AC power switching circuits
Procurement Notes
Verify the specific suffix designation against official Littelfuse documentation to confirm exact pinout configuration and packaging variant. Ensure that the selected component meets all required environmental compliance standards for the target deployment region before finalizing procurement orders.
Selection Notes
Select this component when a 400 V blocking voltage and 6 A continuous current rating are required in a standard through-hole form factor. The sensitive gate characteristic makes it suitable for microcontroller-driven interfaces where minimal drive current is available. Verify thermal dissipation requirements for the intended load conditions.
Part Context
This part belongs to the Sxx06xSx series of thyristors manufactured by Littelfuse. The series provides standardized performance metrics for general-purpose power switching. The RS2 suffix typically denotes specific packaging and terminal configurations within the broader product family.
Replacement Considerations
Direct replacements include the S4006LS2TP and S4006DS2TP. These alternatives offer identical electrical ratings but differ in package style or tab isolation characteristics. Confirm mechanical fit and thermal interface compatibility before substitution.
