Overview
The PS2703-1-V-F3-K-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates a GaAs infrared LED with an NPN phototransistor in a 4-pin SOP package. Key electrical parameters include a collector-emitter voltage of 120 V, a maximum forward current of 50 mA, and an isolation voltage of 3750 Vrms. The device offers a minimum current transfer ratio of 100% and a maximum of 300%, with a typical forward voltage of 1.1 V.
Feature Summary
- High isolation voltage capability for safe signal transmission between isolated circuits
- High collector-to-emitter voltage rating suitable for demanding switching applications
- SOP package design provides shielding against ambient light interference
Applications
- Hybrid ICs requiring galvanic isolation
- Telephone and fax machine interface circuits
- Programmable logic controller input/output stages
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific suffix variations against official datasheets. Check for obsolescence notices as this part may be discontinued. Ensure storage conditions meet moisture sensitivity level requirements before assembly.
Selection Notes
Select this component when high voltage isolation and robust collector-emitter ratings are required. The NPN output type suits standard digital switching interfaces. Verify that the 120 V collector voltage meets circuit requirements. Consider the SOP-4 package constraints for PCB layout density compared to other form factors.
Part Context
This device belongs to the PS2703 series of high isolation voltage optocouplers. It shares architectural similarities with PS2703-1-E3 and E4 variants but differs in packaging and compliance specifications. The series utilizes GaAs LED technology for efficient optical coupling within a compact plastic outline package designed for surface mount applications.
Replacement Considerations
Official substitutes include PS2703-1-E3 and PS2703-1-E4. Verify pinout compatibility and electrical parameter equivalence before substitution. Cross-reference with PS2703-1-V-F3-A if lead-free processing is mandatory.
