PS8802-1-A

Overview

The PS8802-1-A is a high-speed photovoltaic output optoisolator from the NEPOC series, manufactured by CEL. It integrates a GaAlAs LED input with a PIN photodiode and high-speed amplifier transistor on a single chip. The device operates in an 8-pin SSOP package and provides a minimum isolation voltage of 2500 Vrms. It supports a maximum supply voltage of 35 V and features a high common mode transient immunity of ±10 kV/µs. The typical propagation delay is 0.8 µs for low-to-high transitions and 1.2 µs for high-to-low transitions.

Feature Summary

• High common mode transient immunity designed for noisy environments
• Compact footprint reducing mounting area compared to dual SOP configurations
• Integrated analog output type architecture for signal isolation
• Compliant with UL and DIN EN60747-5-2 safety standards

Applications

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

Procurement Notes

Verify the specific suffix code against the manufacturer's current datasheet to confirm pinout compatibility and tape/reel specifications. Ensure the ordering number matches the required packaging quantity, as variants exist for different reel sizes. Confirm that the safety certification numbers align with regional regulatory requirements for the final assembly.

Selection Notes

Select this component when high common mode noise rejection is critical for signal integrity. The analog output type requires appropriate biasing circuitry on the receiving end. Consider the 8-pin SSOP package constraints for PCB layout density. Verify that the 35 V supply limit accommodates the system's operating voltage margins.

Part Context

This part belongs to the PS8802 family of high-speed photocouplers developed by California Eastern Labs (CEL). The family includes variants such as PS8802-2 for specific density applications. These devices are successors to earlier NEC Corporation designs, maintaining the NEPOC technology lineage for reliable optical isolation in modern electronic systems.

Replacement Considerations

Direct substitutes include other parts within the PS8802 series, such as the PS8802-2, which shares similar electrical characteristics but may differ in pin configuration or mounting area optimization.
