PS2801-1-F3-L-A

Overview

The PS2801-1-F3-L-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates a GaAs infrared emitting diode and an NPN silicon phototransistor within a compact SSOP-4 surface-mount package. The device provides high isolation voltage of 2500 Vrms, ensuring effective electrical separation between input and output circuits. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a forward current rating of 50 mA, and a forward voltage of 1.4 V. The current transfer ratio ranges from 100% to 300%, supporting reliable signal transmission in high-density applications.

Feature Summary

• Integrates a GaAs light emitting diode and an NPN silicon phototransistor for optical signal coupling
• Provides high insulation voltage capability to ensure safe electrical isolation between circuits
• Features a shielded SSOP-4 package design that effectively blocks ambient light interference

Applications

• High-density electronic circuit designs requiring compact isolation solutions
• Industrial control systems needing reliable signal transmission across isolated boundaries
• Measurement instruments requiring precise electrical isolation for accurate data acquisition

Procurement Notes

Verify component authenticity through official Renesas channels or authorized distributors. Confirm the specific suffix matches the required tape and reel configuration. Check current supply status as availability may be restricted. Ensure compliance with RoHS standards and relevant safety certifications before integration into final products.

Selection Notes

Select this component when a single-channel isolation solution with high voltage tolerance is required. Consider the SSOP-4 package size constraints for PCB layout. Evaluate the current transfer ratio range against system gain requirements. Verify that the operating temperature range meets the environmental conditions of the intended application.

Part Context

This part belongs to the PS2801 series of high-isolation voltage photocouplers. The series offers various channel configurations and package options to suit different density requirements. The F3 suffix typically indicates a specific tape and reel packaging format suitable for automated assembly processes. The L-A suffix denotes specific manufacturing or regional compliance attributes defined by the manufacturer.

Replacement Considerations

Direct substitutes within the same family include PS2801-1-F3. Cross-referencing with other manufacturers requires careful verification of pinout compatibility, isolation voltage ratings, and package dimensions to ensure functional equivalence without redesigning the host circuit.
