Overview
The PS2703-1-F3-K-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics Corporation. It provides an isolation voltage of 3750Vrms and operates within a temperature range of -55°C to +100°C. The device features a maximum collector-emitter voltage of 120V and a maximum collector current of 30mA. Key electrical parameters include a typical forward voltage of 1.4V, a maximum DC forward current of 50mA, and a maximum collector-emitter saturation voltage of 300mV. The component is housed in a 4-SMD,鸥翼 (gull-wing) package.
Feature Summary
- High isolation voltage capability for robust signal transmission across potential barriers
- Wide operating temperature range suitable for demanding industrial environments
- Surface-mount packaging designed for automated assembly processes
Applications
- Industrial control systems requiring galvanic isolation
- Measurement equipment input stages
- Power supply feedback loops
Procurement Notes
Verify the specific suffix K-A against official Renesas documentation to confirm pinout and marking details. Confirm RoHS compliance status as per the latest datasheet revision. Check for any Product Change Notices (PCN) regarding manufacturing location or material changes before finalizing procurement plans.
Selection Notes
Select this component when a high-voltage isolated interface with NPN phototransistor output is required. Ensure the 120V collector-emitter voltage rating meets the load requirements. Verify that the 30mA collector current limit is sufficient for the application. Consider the 4-SOP package dimensions for PCB layout constraints.
Part Context
This part belongs to the PS2703 series of transistor output optocouplers from Renesas. The series is characterized by high isolation voltage and compact surface-mount packaging. It serves as a standard solution for isolating low-voltage control signals from higher-voltage power circuits in various electronic assemblies.
Replacement Considerations
Consult official Renesas substitution guides for verified alternatives. Cross-reference with other manufacturers only if pin-compatible and electrically equivalent specifications are confirmed through independent datasheet analysis.
