PS2703-1-A

Overview

The PS2703-1-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates a Gallium Arsenide (GaAs) infrared emitting diode and an NPN phototransistor within a plastic SOP-4 package. The device provides high isolation voltage of 3750 Vrms and supports a collector-emitter breakdown voltage of 120 V. Key electrical parameters include a maximum forward current of 50 mA, a typical current transfer ratio of 150%, and a maximum dark power of 100 nA. It operates within a temperature range of -55 °C to 100 °C.

Feature Summary

• High isolation voltage capability for safe signal transmission between circuits
• High collector-to-emitter voltage rating suitable for demanding switching applications
• SOP-4 package design with shielding effect to minimize ambient light interference

Applications

• Hybrid ICs requiring compact isolation solutions
• Telephone and FAX equipment interfaces
• Programmable logic controllers (PLCs)

Procurement Notes

Verify the specific suffix 'A' against official Renesas documentation to confirm lead-free status and RoHS compliance, as suffixes often dictate environmental certifications. Confirm availability status, as this part may be subject to discontinuation or limited supply notifications. Ensure the ordering code matches the exact pinout and packaging requirements for your PCB layout.

Selection Notes

Select this component when a high collector-emitter voltage of 120 V is required in a small form factor. The SOP-4 package is ideal for high-density surface mount applications. Consider the typical current transfer ratio and switching speeds to ensure compatibility with the driving circuit's timing requirements and load conditions.

Part Context

This component belongs to the PS2703 series of high isolation voltage optocouplers from Renesas. The series includes variants like PS2703-1-E3 and PS2703-1-V-E4, which share similar functional characteristics but may differ in packaging options, environmental compliance, or specific approval ratings such as UL or VDE.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with direct replacements by matching the SOP-4 package, 120 V collector-emitter voltage, and transistor output type.
