Overview
The Littelfuse S6X8ECS2 is a sensitive Gate Turn-Off (GTO) SCR from the SxX8xSx series, designed for low-power applications. It features a rated repetitive off-state voltage (VDRM) of 600 V and an on-state RMS current (IT(RMS)) of 0.8 A. The device operates within a temperature range of -40°C to +125°C and utilizes a TO-92 package for through-hole mounting. Key electrical parameters include a gate trigger voltage (VGT) of 800 mV, a gate trigger current (IGT) of 1 µA, and a holding current (IH) maximum of 5 mA. Off-state leakage current is specified at 3 µA under VDRM conditions.
Feature Summary
- Designed specifically for Ground Fault Circuit Interrupter (GFCI) applications
- Optimized for gas ignition systems requiring sensitive gate control
- Features high static dv/dt capability with low turn-off time
Applications
- Ground Fault Circuit Interrupters (GFCI)
- Gas ignition systems
- Low power thyristor switching circuits
Procurement Notes
Verify the specific suffix and package configuration against the official Littelfuse datasheet to ensure compatibility with GFCI or ignition requirements. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary. Ensure the selected component matches the required thermal and electrical specifications for the target application environment.
Selection Notes
Select the S6X8ECS2 when a sensitive GTO SCR is required for GFCI or gas ignition designs. Consider its 600 V rating and 0.8 A current capacity relative to load demands. Evaluate the TO-92 through-hole package for PCB layout constraints. Compare gate sensitivity and turn-off characteristics against alternative devices in the SxX8xSx family to ensure optimal circuit performance.
Part Context
The S6X8ECS2 belongs to the SxX8xSx EV Series, a line of thyristors characterized by small die planar construction. This series emphasizes high static dv/dt immunity and rapid turn-off times, making it suitable for precise control applications. The component represents Littelfuse's focus on efficient electrical energy transfer solutions for safety-critical and ignition-based systems.
Replacement Considerations
Consult the official Littelfuse substitution guide for verified alternatives within the SxX8xSx series. Ensure any replacement maintains equivalent VDRM, IT(RMS), and package dimensions. Verify that gate trigger parameters remain compatible with the existing drive circuitry before implementing a substitute part number.
