Overview
The Littelfuse S6X8ES2AP is a Silicon Controlled Rectifier (SCR) from the SxX8xSx series, housed in a TO-92 through-hole package. It features a rated repetitive off-state voltage (VDRM) of 600 V and an on-state RMS current (It RMS) of 800 mA. The device has a maximum holding current (Ih) of 5 mA, a forward voltage (Vf) of 1.7 V, and a gate trigger voltage (Vgt) of 800 mV with a gate trigger current (Igt) of 50 uA. Off-state leakage current is 3 uA at VDRM. Operating temperature ranges from -40 C to +125 C.
Feature Summary
- Provides solid-state switching capability for AC control applications
- Integrated thermal protection via glass passivated junctions
- Compact leaded package suitable for space-constrained PCB layouts
Applications
- AC power control circuits
- Lighting dimmer applications
- Motor speed control systems
Procurement Notes
Verify the specific ordering suffix when sourcing. The provided data references S6X8ES2AP, which indicates Ammo Pack packaging. Confirm that the required suffix matches the intended reel or tape configuration for your assembly process. Ensure RoHS compliance status is validated against the latest manufacturer documentation before finalizing procurement orders.
Selection Notes
Select this component based on its 600 V blocking voltage and 800 mA continuous current rating. Verify that the 50 uA gate trigger current aligns with your driver circuit capabilities. Consider the TO-92 package constraints for thermal dissipation and mounting orientation relative to other board components during the design phase.
Part Context
This SCR belongs to the SxX8xSx family of thyristors manufactured by Littelfuse. These devices are designed for general-purpose switching and are commonly used in consumer electronics and industrial control panels where reliable AC switching is required within standard voltage and current limits.
Replacement Considerations
Check for direct substitutes within the same SxX8xSx series that match the 600V/800mA specifications. Verify pinout compatibility and package dimensions before substituting with equivalent parts from other manufacturers to ensure mechanical fit.
