PS2801-4-F3

Overview

The PS2801-4-F3-A is a transistor output optoisolator manufactured by CEL, featuring four independent channels within a single package. It provides high isolation voltage of 2500Vrms between input and output circuits. The device utilizes a GaAs light emitting diode coupled with NPN silicon phototransistors to ensure reliable signal transmission across isolated boundaries. Designed for surface mount applications, it offers a compact form factor suitable for space-constrained designs.

Feature Summary

• High isolation voltage capability for safe circuit separation
• Compact thin package design with small pin pitch
• Four-channel configuration for multi-signal isolation

Applications

• Industrial control systems requiring galvanic isolation
• Communication equipment signal interfacing
• Power supply feedback loops

Procurement Notes

Verify the specific suffix -F3-A against current manufacturer catalogs as component availability may vary. Confirm that the requested part matches the exact pinout and electrical specifications required for your design. Check for obsolete status or recommended replacements if new production units are unavailable. Ensure compliance with RoHS directives if applicable to your region.

Selection Notes

Select this component when multiple isolated channels are needed in a compact footprint. Consider the 2500Vrms isolation rating for safety requirements. Evaluate the operating temperature range of -55°C to 100°C against environmental conditions. Verify compatibility with surface mount assembly processes due to the SSOP package type.

Part Context

This component belongs to the PS2801 series of optocouplers, which are widely used for isolating digital signals. The series typically includes variants with different channel counts and package styles. Renesas Electronics is the original designer, while CEL distributes specific suffixes. These devices are standard solutions for noise immunity in mixed-signal environments.

Replacement Considerations

PS2801-4-A is listed as a similar substitute option. Verify pin compatibility and electrical parameters before substitution. Ensure the replacement meets all isolation voltage and current transfer ratio requirements of the original design.
