PS2911-1-V-F3-L-A

Overview

The PS2911-1-V-F3-L-A is a photovoltaic output optoisolator featuring a GaAs infrared LED and an NPN silicon phototransistor. It provides 2500Vrms isolation voltage with a minimum current transfer ratio of 150% at 1mA input. The device supports a maximum output voltage of 40V and handles 40mA per channel. Typical forward voltage is 1.1V. Operating temperature ranges from -55°C to 100°C.

Feature Summary

• High current transfer ratio for efficient signal transmission
• Ultra-small 4-pin flat-lead package design
• Robust 2500Vrms electrical isolation capability

Applications

• Industrial control systems requiring galvanic isolation
• Measurement equipment input stages
• Power supply feedback loops

Procurement Notes
