PS2805C-4-V-A

Overview

The PS2805C-4-V-A is a quad-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates a GaAs infrared LED and NPN phototransistors in a 16-pin SSOP package with a 1.27 mm pin pitch. The device provides an isolation voltage of 2500 Vrms and supports AC input response. Key electrical parameters include a collector-emitter voltage of 80 V, maximum forward current of 30 mA, and a current transfer ratio ranging from 50% to 400%. Operating temperatures span from -55°C to +100°C.

Feature Summary

• Supports AC input signal coupling

Applications

• Programmable logic controllers
• OA equipment
• Measurement instruments

Procurement Notes

Verify the specific suffix 'V' against official Renesas documentation to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status through the manufacturer's datasheet. Ensure the component meets required safety certifications such as UL or VDE if applicable to the design. Check for obsolescence notices prior to finalizing procurement plans.

Selection Notes

Select this component when four isolated channels are required within a compact surface-mount footprint. The 80 V collector-emitter voltage rating suits general-purpose switching applications. Verify that the 50% minimum CTR meets the drive requirements of the downstream load. Ensure the operating temperature range aligns with the environmental conditions of the target system.

Part Context

This part belongs to the PS2805C series of optically coupled isolators. The series utilizes GaAs LEDs and silicon NPN phototransistors to achieve electrical isolation. The 16-pin SSOP variant offers multiple channels in a single package, reducing board space compared to discrete solutions while maintaining high isolation performance standards.

Replacement Considerations

Consult official substitution lists for direct equivalents. Generic replacements may differ in isolation voltage or package dimensions. Verify pin compatibility and electrical characteristics before integrating alternative components into existing designs.
