Overview
The PS2703-1-V-F3-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 maximum collector-emitter voltage of 120 V, a maximum collector current of 30 mA, and an isolation voltage of 3750 Vrms. The device features a typical forward voltage of 1.1 V at a maximum forward current of 50 mA. Current transfer ratio ranges from 100% to 300%. Operating temperature spans from -55°C to +100°C.
Feature Summary
- High isolation voltage capability of 3750 Vrms for robust circuit protection
- High collector-to-emitter breakdown voltage rated at 120 V
- SOP-4 plastic package design provides shielding against ambient light interference
- Fast switching performance suitable for high-speed signal transmission
Applications
- Hybrid ICs requiring galvanic isolation
- Telephone and fax machine interface circuits
- Programmable logic controllers (PLCs)
Procurement Notes
Verify the specific suffix F3-A corresponds to the required tape and reel packaging configuration. Confirm RoHS compliance status as indicated in official documentation, noting potential variations between E3/E4 and F3/F4 designations. Ensure the component meets UL and VDE safety approval requirements for the target application environment before finalizing procurement specifications.
Selection Notes
Select this component when a 120 V collector-emitter voltage rating is necessary, distinguishing it from lower-voltage variants like the PS2701 or PS2702. The NPN phototransistor output is appropriate for standard digital switching applications. Consider the SOP-4 package dimensions for PCB layout constraints and verify that the 30 mA collector current limit satisfies the load requirements of the isolated side circuitry.
Part Context
This part belongs to the PS2703 series of high-isolation voltage optocouplers. The series includes dual-channel (PS2703-2) and quad-channel (PS2703-4) variants sharing similar electrical characteristics. The PS2703-1 specifically offers a single isolated channel within the compact SOP-4 footprint, designed for high-density mounting in electronic assemblies requiring reliable signal transmission across isolation barriers.
Replacement Considerations
Direct substitutes within the same family include PS2703-1-E3, PS2703-1-E4, and PS2703-1-F4. Verify that alternative suffixes match the required packaging format and regulatory approvals. Cross-referencing with other manufacturers requires matching the 120 V C-E voltage, 3750 Vrms isolation, and NPN output type.
