PS9851-2-V-AX

Logic Output Optoisolators Overview

The PS9851-2-V-AX is a dual-channel logic output optoisolator manufactured by Renesas Electronics. It features a GaAlAs LED input and CMOS output, providing 2500Vrms isolation voltage and 10kV/µs common mode transient immunity. The device supports data rates up to 15Mbps with propagation delays of 60ns maximum. It operates on a 4.5V to 5.5V supply within a -40°C to 100°C temperature range. Packaged in an 8-SSOP surface mount format, it delivers 2mA output current per channel.

Logic Output Optoisolators Feature Summary

• High-speed digital isolation with 15 Mbps data rate capability
• Robust noise immunity via 10 kV/µs common mode transient rejection
• CMOS output stage for low power consumption and fast switching

Logic Output Optoisolators Applications

• Industrial automation control systems
• Power supply feedback loops
• Communication interface isolation

Logic Output Optoisolators Procurement Notes

Verify the specific suffix 'V-F3-AX' against the requested part number, as distributor listings may indicate this variant. Confirm the package type matches the required 8-SSOP form factor. Ensure the operating temperature range meets the application's thermal requirements. Check for RoHS compliance documentation if environmental regulations apply. Validate the manufacturer source to avoid counterfeit components.

Logic Output Optoisolators Selection Notes

Select this component when high-speed signal transmission across isolation barriers is required. The CMOS output provides better noise margins compared to phototransistor outputs. Consider the 2500Vrms isolation rating for safety-critical applications. The wide operating temperature range suits harsh industrial environments. Verify that the 2mA output current is sufficient for the downstream logic load.

Logic Output Optoisolators Part Context

This device belongs to the NEPOC series of high-speed photocouplers from Renesas. It complements single-channel variants like the PS9851-1 for applications requiring multiple isolated channels. The series is designed to replace older discrete isolation solutions with integrated, compact packages.

Logic Output Optoisolators Replacement Considerations

Direct substitutes include the PS9851-2-AX or PS9851-2-V-AX. Verify pinout compatibility before swapping. Ensure replacement parts meet the same 15 Mbps speed and 2500Vrms isolation specifications.
