Overview
The Littelfuse S4006LS2 is a sensitive gate silicon-controlled rectifier (SCR) designed for through-hole mounting in the TO-220 package with an isolated tab. It features a maximum repetitive peak off-state voltage of 400 V and an RMS on-state current rating of 6 A. The device supports a non-repetitive surge current of up to 100 A at 60 Hz. Key electrical parameters include a maximum gate trigger voltage of 800 mV, a maximum gate trigger current of 200 µA, and a maximum on-state voltage of 1.6 V. It operates within a junction temperature range of -40°C to 110°C.
Feature Summary
- Sensitive gate architecture enabling reliable triggering with low gate current requirements.
Applications
- General purpose power control circuits requiring high surge tolerance.
Procurement Notes
Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches the TO-220 isolated tab configuration. Ensure the sensitive gate variant aligns with circuit design requirements for low trigger currents. Validate RoHS3 compliance status if environmental regulations apply to the final assembly.
Selection Notes
Select this SCR when a 400 V blocking capability and 6 A continuous current are required in a standard through-hole format. The sensitive gate characteristic simplifies drive circuitry compared to standard gate devices. Consider thermal management needs given the 1.6 V on-state voltage drop at full load. Verify that the TO-220 isolated tab provides sufficient insulation for the intended application voltage.
Part Context
This component belongs to the Littelfuse SCR family, specifically engineered for robust power switching applications. The S4006LS2 designation indicates a 400 V rating within the series. It serves as a discrete semiconductor solution for controlling AC or DC loads where isolation between the gate and main terminals is necessary via the isolated tab package.
Replacement Considerations
The S4006LS2TP is documented as a parameter-equivalent substitute from Littelfuse Inc. Verify pinout compatibility and ensure the replacement maintains the same TO-220 isolated tab configuration and electrical ratings before implementation.
