Triac, SCR Output Optoisolators datasheet and documents for S2S4

S2S4

Triac, SCR Output Optoisolators Overview

The Sharp Microelectronics S2S4 is a single-channel phototriac coupler designed for surface-mount applications in a SOP-4 package. It integrates an infrared LED with a zero-crossing detection triac output, providing high isolation of 3750 Vrms. The device supports a maximum repetitive peak off-state voltage of 600 V and a continuous RMS current of 50 mA. Key electrical parameters include a forward current of 50 mA, a forward voltage of 1.2 V, and a trigger current of 10 mA. Operating temperatures range from -30°C to +100°C.

Triac, SCR Output Optoisolators Feature Summary

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., F, AY) against the datasheet to ensure correct packaging and feature alignment. Confirm RoHS compliance status as indicated in official documentation. Check lead times and production cycles prior to ordering. Ensure the selected variant matches the required zero-crossing or non-zero-crossing functionality for the target application.

Triac, SCR Output Optoisolators Selection Notes

Select this component when high-voltage AC isolation is required with minimal noise generation. The integrated zero-crossing feature makes it suitable for sensitive loads. Consider the SOP-4 footprint for PCB space constraints. Verify that the 50 mA output current rating meets the load requirements. Compare with similar models like S2S3A00F if zero-crossing is not needed.

Triac, SCR Output Optoisolators Part Context

The S2S4 series belongs to Sharp's family of phototriac optocouplers. These devices are engineered for reliable AC switching in industrial and consumer electronics. The series includes variants with and without zero-crossing detection. They offer robust performance in harsh environments due to wide operating temperature ranges and high isolation capabilities.
