PS2707-1-A

Overview

The PS2707-1-A is a transistor output optoisolator manufactured by CEL, belonging to the NEPOC series. It features a single channel with 3750Vrms isolation voltage and a minimum current transfer ratio of 50% at 5mA input current. The device utilizes a GaAs LED coupled with an NPN silicon phototransistor in a 4-SMD Gull Wing package. Operating temperature ranges from -55°C to 100°C with a maximum Vce saturation of 300mV. This component is currently obsolete and no longer manufactured.

Feature Summary

• Contains GaAs light emitting diode and NPN silicon phototransistor for optical coupling
• Provides high collector to emitter voltage capability
• Supports AC and DC input types

Applications

• Digital signal transmission and isolation
• General purpose isolation circuits
• Industrial control systems requiring galvanic isolation

Procurement Notes

Verify part status carefully as this specific model is listed as obsolete. Confirm availability through authorized distributors or secondary markets. Ensure substitute components meet original electrical specifications including isolation voltage and current transfer ratio requirements before integration into existing designs.

Selection Notes

Consider the NEPOC series alternatives when sourcing replacements. Evaluate pin compatibility and package dimensions for direct board replacement. Verify that substitute devices maintain equivalent isolation ratings and operating temperature ranges to ensure system reliability without redesigning surrounding circuitry.

Part Context

This component belongs to the PS2707 family of optoisolators produced by NEC, now part of Renesas Electronics. The PS2707-1 variant specifically denotes a single-channel configuration. Manufacturing rights and documentation have transitioned through corporate acquisitions, affecting current production status and support channels.

Replacement Considerations

PS2707-1-F3 is identified as a taping product alternative within the same series. Verify pinout compatibility and electrical parameters against original specifications before substitution.
