PS8741-F3-A

Overview

The PS8741-F3-A is a dual-channel optically coupled isolator manufactured by CEL. It integrates a Gallium Arsenide (GaAs) light-emitting diode on the input side with two photodiodes on the output side. The device provides an isolation voltage of 1500Vrms and features a linearized photovoltaic output. It is housed in a 16-SOP surface-mount package with a width of 4.40mm. The component operates within a temperature range of -40°C to 85°C, with a maximum forward current of 50mA and a nominal forward voltage of 1.1V.

Feature Summary

Dual-channel optical isolation using GaAs LED input and photodiode outputs
Linearized photovoltaic output for analog signal transmission
High isolation voltage rating of 1500Vrms
Surface-mount 16-SOP package design

Applications

Optical Data Access Adapter (DAA) circuits
Analog control systems requiring galvanic isolation
Telecommunications interface modules

Procurement Notes

Verify the specific suffix (F3-A) against official datasheets to confirm pinout and electrical characteristics, as variations exist within the PS8741 family. Confirm end-of-life status with the manufacturer or authorized distributors prior to finalizing procurement plans. Ensure compatibility with existing PCB footprints for the 16-SOP package.

Selection Notes

Select this component when high linearity is required for analog signal isolation rather than digital switching. The dual-channel configuration supports differential signaling applications. Verify that the 1500Vrms isolation rating meets the safety requirements of the target system. Consider the operating temperature range of -40°C to 85°C for environmental suitability.

Part Context

The PS8741 series belongs to the Nepoc product line from CEL, designed for high-performance optical isolation. These devices are specifically engineered for applications demanding precise analog signal transfer across isolation barriers. The series includes various packaging and suffix options to accommodate different board layout and performance needs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consult the manufacturer's cross-reference guide for equivalent components if this part is discontinued or unavailable.
