S2S5A

Triac, SCR Output Optoisolators Overview

The S2S5A is a single-channel Triac output optocoupler manufactured by Sharp Microelectronics. It features a PhotoTriac output with an isolation voltage of 3750 Vrms and does not include a zero-crossing circuit. The device operates within a temperature range of -30°C to +100°C and utilizes a SOP-4 surface-mount package. Key electrical parameters include a forward current of 50 mA, a forward voltage of 1.2 V, and a maximum repetitive peak off-state voltage (VDRM) of 600 V. The maximum trigger current is specified at 10 mA, with a maximum turn-on time of 100 us.

Triac, SCR Output Optoisolators Feature Summary

• Provides high-voltage electrical isolation between input and output circuits via optical coupling.
• Designed for noise-resistant operation in triac control applications without zero-crossing detection.
• Utilizes a compact SOP-4 surface-mount package for efficient PCB integration.

Triac, SCR Output Optoisolators Applications

• Solid-state relay driver circuits
• AC power switching control systems
• Industrial motor control interfaces

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix designation when ordering, as variants such as S2S5A00F may exist with identical core specifications but different packaging or tape-and-reel configurations. Confirm RoHS compliance status through official documentation prior to procurement. Ensure the selected variant matches the required zero-crossing absence for the intended application design.

Triac, SCR Output Optoisolators Selection Notes

Select this component when a non-zero-crossing triac output is required for phase-angle control applications. The 600 V blocking voltage suits low-to-medium voltage AC loads. Consider the 100 us turn-on time for timing-sensitive designs. Compare against zero-crossing variants like the S2S4 series if EMI reduction is prioritized over precise phase control.

Triac, SCR Output Optoisolators Part Context

The S2S5A belongs to Sharp’s family of Triac and SCR output optocouplers. It shares the SOP-4 footprint and basic isolation characteristics with related models but differs in its lack of zero-crossing circuitry. This distinguishes it from zero-crossing variants within the same product line, making it suitable for applications requiring immediate response to input signals rather than synchronized switching.

Triac, SCR Output Optoisolators Replacement Considerations

Direct substitutes within the Sharp lineup include the S2S5A00F, which maintains the same electrical profile. Cross-manufacturer replacements require matching the 3750 Vrms isolation, 600 V VDRM, and SOP-4 package dimensions. Verify that alternative parts also lack zero-crossing functionality to ensure circuit compatibility.
