PS8802-2-AX

Overview

The PS8802-2-AX is a dual-channel high-speed optocoupler manufactured by Renesas Electronics. It integrates a GaAlAs LED input with a PIN photodiode and amplifier output on a single chip, delivering analog output characteristics. Key electrical parameters include a data speed of 1 Mbps, an absolute maximum power supply voltage of 35 V, and an isolation voltage of 2500 Vrms. The device features a minimum common mode transient immunity of 15 kV/µs, with propagation delays of 0.8 µs (max) for low-to-high transitions and 1.2 µs (max) for high-to-low. It operates within a temperature range of -55°C to +100°C and utilizes an SSOP-8 package.

Feature Summary

• High common mode transient immunity designed for noisy environments
• Dual-channel configuration reduces mounting area compared to single-channel equivalents
• High-speed response suitable for rapid signal transmission
• Integrated GaAlAs LED and PIN photodiode technology

Applications

• High-density digital isolator circuits
• Industrial control systems requiring high CMR
• Data communication interfaces
• Power supply feedback loops

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as PS8802-2-F3 indicate tape-and-reel packaging configurations. Confirm that the selected part number aligns with the required safety approvals, including UL and VDE standards, if applicable to the final equipment certification. Ensure compatibility with the intended operating temperature range and voltage levels before integration into the design.

Selection Notes

Select this component for applications demanding high density and fast signal isolation. The dual-channel layout offers space efficiency over two separate single-channel devices. Consider the 1 Mbps data rate and 15 kV/µs CMR limits to ensure suitability for the specific noise environment. Verify that the SSOP-8 package fits the PCB footprint constraints and that the 35 V max supply voltage meets the system requirements.

Part Context

The PS8802-2-AX belongs to the NEPOC series of high-speed optocouplers from Renesas Electronics. This series focuses on providing robust isolation with high common mode rejection capabilities. The PS8802-2 variant specifically addresses high-density application needs by combining two channels in a compact form factor, distinguishing it from the single-channel PS8802-1 model.
