S2S4B00F

Triac, SCR Output Optoisolators Overview

The S2S4B00F is a Triac and SCR output optocoupler manufactured by Sharp Microelectronics. It features a PhotoTriac output with an integrated zero-crossing circuit, designed for noise-immune switching applications. The device provides high isolation with an insulation voltage of 3750 Vrms. Key electrical parameters include a maximum forward current (If) of 50 mA, a forward voltage (Vf) of 1.2 V, and a peak repetitive off-state voltage (VDRM) of 600 V. The maximum trigger current (Ift) is 10 mA, and the RMS on-state current (It RMS) is rated at 50 mA. The component operates within a temperature range of -30°C to +100°C and is housed in a SOP-4 surface-mount package.

Triac, SCR Output Optoisolators Feature Summary

• Integrates a zero-crossing detection circuit to minimize electromagnetic interference during AC load switching.
• Provides robust electrical isolation between input and output circuits via a 3750 Vrms insulation rating.
• Utilizes a compact SOP-4 surface-mount package suitable for automated assembly processes.

Triac, SCR Output Optoisolators Applications

• Solid-state relays for AC power control
• Motor control interfaces
• Industrial automation systems requiring isolated triac driving

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Sharp Microelectronics or authorized distributors before procurement. Confirm that the SOP-4 package dimensions match the target PCB footprint. Ensure the supply chain source is authorized to guarantee component authenticity and traceability. Check for any recent product change notifications that may affect pinout or electrical characteristics.

Triac, SCR Output Optoisolators Selection Notes

Select the S2S4B00F when zero-crossing switching is required to reduce electrical noise in AC applications. Compare it against non-zero-crossing variants like the S2S3A00F if phase-angle control is needed instead. Ensure the 600 V blocking voltage and 50 mA current ratings exceed the load requirements. Verify that the 3750 Vrms isolation level meets the safety standards of the end equipment.

Triac, SCR Output Optoisolators Part Context

This component belongs to Sharp's series of Triac and SCR output optocouplers. It is functionally related to other models in the S2S family, such as the S2S4A00F and S2S4RA0F, which share similar packaging and basic isolation characteristics but may differ in specific electrical thresholds or internal circuit configurations.

Triac, SCR Output Optoisolators Replacement Considerations

The S2S4A00F is a confirmed substitute part number within the same product family. Verify compatibility regarding the zero-crossing circuit operation and ensure the replacement matches the SOP-4 package outline and pin assignment.
