PS2811-1-F3-A

Overview

The PS2811-1-F3-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 thin, lead-free plastic SSOP-4 package with a 1.27 mm pin pitch. The device provides high isolation voltage of 2500 Vrms and supports a collector-emitter breakdown voltage of 40 V. It features a nominal current transfer ratio of 100%, maximum forward current of 50 mA, and operates within a temperature range of -55 °C to 100 °C.

Feature Summary

High isolation voltage capability for reliable signal transmission across electrical barriers
Thin SSOP package design optimized for high-density surface-mount applications
Integrated shield effect to minimize interference from ambient light sources

Applications

Industrial control systems requiring galvanic isolation
Power supply feedback loops for voltage regulation
Signal transmission between microcontrollers and peripheral devices

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm exact packaging and compliance status. Ensure the component matches the required isolation voltage and package dimensions for your PCB layout. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and availability.

Selection Notes

Select this component when a single-channel isolation solution with a compact footprint is required. Consider the 40 V collector-emitter voltage rating for low-voltage switching applications. Verify that the operating temperature range meets the environmental conditions of the target system.

Part Context

This component belongs to the PS2811 series of photo couplers designed for general-purpose isolation. It shares the same physical package and basic functionality as variants like the PS2811-1-F3-M-A, differing primarily in specific manufacturing batches or minor compliance markings. The series is widely used in consumer and industrial electronics for safe signal transfer.
