PS8602L2-A

Overview

The PS8602L2-A is a high-speed analog output type photocoupler featuring an 8-pin surface mount package. It integrates a GaAlAs LED on the input side with a P-N photodiode and high-speed amplifier transistor on the output side within a single chip. The device provides high common mode transient immunity and supports high supply voltages up to 35V. It offers a minimum isolation voltage of 5000 Vrms and fast response times, making it suitable for noise-sensitive applications requiring reliable signal transmission across isolated boundaries.

Feature Summary

• High common mode transient immunity for robust noise reduction
• High speed response capability for rapid signal processing
• High isolation voltage ensuring safe electrical separation
• Compatible with TTL and CMOS logic families

Applications

• Interface circuits for various instrumentations
• Control equipment signal isolation
• Computer and peripheral manufacturing interfaces

Procurement Notes

Verify the specific suffix 'A' against official manufacturer documentation to confirm exact pinout and mechanical dimensions. Ensure compatibility with infrared reflow soldering processes if automated assembly is planned. Confirm safety approvals such as UL recognition or VDE certification requirements match the target application standards before finalizing procurement.

Selection Notes

Select this component when high-speed analog signal isolation is required in compact surface mount designs. Consider the 5000 Vrms isolation rating for applications demanding significant potential difference between input and output circuits. Evaluate the high common mode transient immunity specifications to ensure adequate performance in electrically noisy environments compared to standard optocouplers.

Part Context

This part belongs to the PS8602 series of high-speed photocouplers manufactured by CEL (formerly NEC). The series includes DIP and surface mount variants designed for high noise reduction. The PS8602L2 specifically denotes the lead bending type for long creepage distance with gull-wing leads, optimized for surface mount technology applications requiring enhanced isolation distances.

Replacement Considerations

The PS8602L2-V is a verified variant within the same family offering similar functional characteristics. Check datasheets for minor mechanical differences between suffixes to ensure board layout compatibility.
