PS2911-1-F3-A

Overview

The PS2911-1-F3-A is a single-channel photovoltaic output optoisolator manufactured by CEL. It features a GaAlAs LED input coupled to a transistor output, providing electrical isolation with a rated voltage of 2500 Vrms. The device operates within a temperature range of -55°C to +100°C and dissipates up to 160 mW. It utilizes a 4-pin ultra-small flat-lead package designed for compact circuit layouts.

Feature Summary

• Photovoltaic output configuration for high isolation
• Ultra-small 4-pin flat-lead package design
• Operable at high temperatures up to 100°C

Applications

• Industrial automation control systems
• Measurement equipment interfaces
• General-purpose signal isolation circuits

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact pinout and packaging variations. Confirm current manufacturing status as some sources indicate this part may be obsolete or replaced by parametric equivalents. Ensure compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component when high isolation voltage and compact form factor are required. The photovoltaic output type suits applications needing galvanic isolation without direct current transfer. Consider thermal dissipation limits and operating temperature ranges during circuit design integration.

Part Context

This part belongs to the NEPOC series of high-speed and standard photocouplers from CEL. It shares family characteristics such as small package dimensions but differs in output type compared to CMOS or logic-output variants. It serves as an isolation bridge between low-voltage control logic and higher-voltage industrial loads.

Replacement Considerations

Public records indicate that the PS2911-1-F3-A is obsolete. Available substitutes include parametric equivalents such as the PS2911-1-F3-AX. Verify functional compatibility and pin alignment before substitution.
