PS2811-1-H-A

Overview

The PS2811-1-H-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and utilizes SSOP-4 surface-mount packaging. The device provides high isolation voltage of 2500 Vrms and supports a maximum forward current of 50 mA with a typical current transfer ratio of 200% at 1 mA input. Key electrical parameters include a collector-emitter saturation voltage of 300 mV, a maximum collector current of 40 mA, and a collector-emitter voltage rating of 40 V.

Feature Summary

• Provides high isolation voltage for circuit separation
• Features high current transfer ratio for efficient signal transmission
• Utilizes compact SSOP-4 surface-mount package

Applications

• General-purpose signal isolation
• Microcontroller interface circuits
• Power supply feedback loops

Procurement Notes

Verify the specific suffix 'H' against official Renesas documentation to confirm pinout and electrical characteristics, as standard variants may differ. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents before integration into production designs.

Selection Notes

Select this component when high current transfer ratio is required for low input current applications. Ensure the 40 V collector-emitter voltage rating meets the load requirements. Verify that the SSOP-4 footprint aligns with the PCB layout constraints and thermal management needs of the target design.

Part Context
