PS8802-2-A

Overview

The PS8802-2-A is a high-speed photocoupler from the NEPOC series, manufactured by CEL. It features an 8-pin SSOP (SO-8) package and integrates a GaAlAs LED on the input side with a PIN photodiode and high-speed amplifier transistor on the output side. Key electrical specifications include a data rate of 1 Mbps, high common mode transient immunity of ±10 kV/µs minimum, a maximum supply voltage of 35 V, and an isolation voltage of 2500 Vrms. Propagation delays are specified as 0.8 µs max for low-to-high and 1.2 µs max for high-to-low transitions.

Feature Summary

• High common mode transient immunity designed for noisy environments
• Compact footprint offering a 40% reduction in mounting area compared to dual 5-pin SOP configurations
• Integrated GaAlAs LED and high-speed amplifier transistor on a single chip
• Compliant with UL and DIN EN60747-5-2 safety standards

Applications

• High-density digital isolator circuits
• Industrial communication interfaces requiring high CMR
• Power supply feedback loops
• Microcontroller input/output isolation

Procurement Notes

Verify the specific suffix code when ordering, as variants such as -F3 or -F4 indicate tape-and-reel packaging quantities. Confirm that the -A suffix denotes the standard lead-free product configuration. Ensure compatibility with 8-pin SSOP footprints during PCB layout. Cross-reference official datasheets for exact mechanical dimensions and thermal characteristics before finalizing procurement specifications.

Selection Notes

Select this component when high common mode transient immunity is critical for signal integrity in electrically noisy environments. The 8-pin SSOP package is suitable for applications requiring space efficiency without sacrificing isolation performance. Consider the 1 Mbps speed limit and 35 V supply voltage constraints when designing circuit interfaces. Verify that the required isolation voltage meets the 2500 Vrms specification for the intended safety classification.

Part Context

The PS8802-2-A belongs to the NEPOC series of optically coupled isolators produced by California Eastern Laboratories (CEL). This series is engineered to provide robust signal transmission across isolation barriers while minimizing physical footprint. The device combines light emission and detection technologies to achieve high-speed response times suitable for modern digital communication protocols.
