Overview
The Littelfuse S6X8ESAP is a silicon-controlled rectifier (SCR) from the SxX8xS series, designed for sensitive gate triggering applications. It features an 800 mA RMS on-state current and a 600 V rated repetitive off-state voltage. The device operates within a temperature range of -40°C to +125°C and utilizes a TO-92 through-hole package. Key electrical characteristics include a maximum holding current of 5 mA, a forward voltage of 1.7 V, and a gate trigger current of 200 µA at 800 mV. It exhibits a low leakage current of 3 µA under rated voltage conditions.
Feature Summary
- Sensitive gate architecture enabling reliable triggering with low gate current requirements
- Robust thermal performance supporting operation in high-temperature environments up to 125°C
- Compact TO-92 through-hole form factor suitable for space-constrained circuit designs
Applications
- General purpose power control circuits requiring sensitive gate activation
- AC/DC conversion systems utilizing thyristor-based regulation
- Industrial switching applications compatible with standard through-hole assembly processes
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number S6X8ESAP with official Littelfuse documentation. Confirm that the received units match the specified TO-92 package and RoHS compliance status. Ensure storage conditions maintain integrity prior to installation, as semiconductor sensitivity requires adherence to handling guidelines provided in the datasheet.
Selection Notes
Select this component when a sensitive gate SCR is required for low-power triggering scenarios. The 800 mA current rating suits light-duty load control, while the 600 V blocking capability provides adequate margin for standard line voltages. Consider the TO-92 package constraints for PCB layout and thermal dissipation requirements relative to the specific application duty cycle.
Part Context
This device belongs to the Littelfuse SxX8xS series of silicon-controlled rectifiers. The series is characterized by its focus on sensitive gate technology, allowing for efficient control with minimal gate drive power. These components are categorized under general-purpose thyristors intended for reliable switching in various electronic control architectures.
Replacement Considerations
Consult official Littelfuse substitution guides for verified equivalents. Ensure any replacement maintains matching voltage ratings, current capabilities, and package dimensions to preserve circuit functionality and mechanical fit without redesign.
