PS8101-F3-AX

Overview

The PS8101-F3-AX is a high-speed optocoupler manufactured by Renesas Electronics, designed for applications requiring robust signal isolation. It features a single channel with a data rate of 1 Mb/s and an insulation voltage of 3750 Vrms. The device utilizes a photo IC output type and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a forward current of 25 mA, a forward voltage of 1.7 V, and a reverse voltage of 5 V. It is housed in a SOP-5 package suitable for surface mount technology.

Feature Summary

• High common mode transient immunity for reliable noise rejection
• Compact SOP-5 plastic package for high-density mounting
• Integrated GaAlAs LED input with PIN photodiode and amplifier output

Applications

• Industrial communication interfaces
• Microcontroller input/output isolation
• Power supply feedback loops

Procurement Notes

Verify the specific suffix F3 against official datasheets to confirm tape-and-reel packaging requirements. Confirm RoHS compliance status through manufacturer documentation before integration. Ensure design-in compatibility with existing SOP-5 footprints and thermal management strategies.

Selection Notes

Select this component when high-speed digital isolation is required alongside compact form factors. The 1 Mbps data rate supports standard industrial protocols. Verify that the 25 mA forward current requirement aligns with the driving circuit capabilities and that the 3750 Vrms isolation rating meets safety standards.

Part Context

This part belongs to the PS8101 series of NEC/Renesas high-speed photocouplers. The series is characterized by its use of GaAlAs LEDs and integrated amplifier transistors on a single chip. It serves as a bridge between low-voltage logic circuits and higher voltage or noisy environments.

Replacement Considerations

Check for direct pin-compatible alternatives within the PS8101 family, such as the PS8101-K-AX or PS8101-V-AX, ensuring output types match application needs.
