PS8602L

Overview

The PS8602L is an 8-pin high-speed photocoupler from the NEPOC series, manufactured by CEL. It integrates a GaAlAs LED on the input side with a P-N photodiode and a high-speed amplifier transistor on the output side within a single chip. The device features a surface-mount Gull-wing plastic package and provides 5000Vrms isolation voltage. It is designed for high common-mode transient immunity and CMOS compatibility.

Feature Summary

• High common-mode transient immunity for noise reduction
• High-speed analog output capability
• CMOS logic compatible interface

Applications

• Industrial automation control systems
• PLC signal transmission
• High-noise environment signal isolation

Procurement Notes

Verify the specific suffix (e.g., -A, -F3) to confirm package type and tape/reel configuration. Confirm current availability status as some variants may be discontinued. Ensure the selected part matches the required isolation voltage and operating temperature range specifications.

Selection Notes

Select this component when high-speed signal transfer and robust noise immunity are required in isolated circuits. The integrated amplifier transistor offers faster response compared to standard phototransistor outputs. Verify that the surface-mount footprint aligns with the PCB design constraints.

Part Context

This device belongs to the NEPOC series of optocouplers. It serves as the surface-mount variant to the through-hole PS8602 DIP package. Both share identical internal circuitry but differ in physical mounting style.

Replacement Considerations

The PS8602 is the direct through-hole equivalent. Check datasheets for pinout compatibility and electrical parameter matching before substitution.
