Overview
The Littelfuse S4006F1 is a Silicon Controlled Rectifier (SCR) designed for power control applications. It features a rated repetitive off-state voltage of 400 V and an RMS on-state current of 6 A. The device operates within a temperature range of -40 °C to +125 °C and utilizes a TO-202AB flange mount package with three terminals. Key electrical characteristics include a gate trigger voltage of 800 mV, a gate trigger current of 200 uA, and a maximum holding current of 6 mA. The forward voltage drop is specified at 1.6 V, ensuring efficient conduction during operation.
Feature Summary
- High gate sensitivity enabling reliable triggering with low input power requirements
- Robust thermal performance suitable for demanding industrial environments
- Flange mount construction facilitating effective heat dissipation
Applications
- Industrial motor speed control systems
- AC power regulation circuits
- Lighting dimmer controls
Procurement Notes
Verify the specific suffix 'F1' against official Littelfuse documentation to confirm pinout and mechanical dimensions. Ensure the procurement channel provides original manufacturer data sheets. Confirm RoHS compliance status through certified test reports before integration into regulated assemblies.
Selection Notes
Select this component when a 400 V blocking capability and 6 A continuous current rating are required in a flange-mount configuration. Evaluate the thermal resistance of the mounting interface to ensure junction temperatures remain within the 125 °C limit under peak load conditions.
Part Context
This SCR belongs to the Sxx06xSx series from Littelfuse, which offers various voltage ratings for the same 6 A current class. The family provides standardized electrical parameters across different voltage grades, allowing designers to scale blocking voltage without changing the physical footprint or current handling capacity.
Replacement Considerations
Cross-reference with other 400 V, 6 A SCRs in TO-202AB packages. Verify that substitute devices match the gate trigger current specifications and thermal characteristics to maintain circuit stability.
