PS2805C-4-F3-A

Overview

The PS2805C-4-F3-A is a four-channel optocoupler from Renesas Electronics, featuring an NPN silicon phototransistor output and a GaAs LED input. It utilizes a 16-pin SSOP package designed for high-density applications with ambient light shielding. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a forward current of 30 mA, and an isolation voltage of 2500 Vrms. The device supports AC input response with typical rise and fall times of 5 μs and 7 μs respectively, operating within a temperature range of -55°C to +100°C.

Feature Summary

• High isolation voltage capability of 2500 Vrms for robust circuit protection
• Compact 16-pin SSOP plastic package with ambient light shielding effect
• Supports AC input response for versatile signal coupling applications

Applications

• Programmable logic controllers
• Office automation equipment
• Measurement instruments
• Mixed integrated circuits

Procurement Notes

Verify the specific suffix F3-A against the official Renesas datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure compliance with relevant safety standards such as UL1577 or CSA CAN/CSA-C22.2 No.62368-1 if required by the target application. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when four isolated channels are required in a compact surface-mount form factor. The 80 V collector-emitter voltage and 30 mA output current suit general digital signal isolation. Consider the 2500 Vrms isolation rating for safety-critical interfaces. Verify that the 16-pin SSOP footprint aligns with the PCB layout constraints and assembly capabilities.

Part Context

This part belongs to the PS2805C series of optical couplers, which integrate GaAs LEDs and NPN phototransistors. The series is designed for high-density applications where space efficiency and cost-performance balance are critical. The PS2805C-4 variant specifically provides four independent channels within a single package, distinguishing it from single-channel counterparts like the PS2805C-1.

Replacement Considerations

Compatible tape product ordering numbers include PS2805C-1-F3 and PS2805C-4-F3. Verify functional equivalence and pin compatibility before substitution. Check for any updates in safety certifications or manufacturing processes via Product Change Notices.
