Overview
The PS2701-1-V-F3-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and is housed in a SOP-4 surface-mount package. The device provides an insulation voltage of 3750 Vrms, ensuring robust electrical isolation between input and output circuits. Key electrical parameters include a collector-emitter voltage of 40 V, a maximum collector current of 80 mA, and a forward voltage of 1.1 V at a forward current of 50 mA. The current transfer ratio ranges from 50% to 300%, with a typical rise time of 3 microseconds.
Feature Summary
- Provides high-voltage electrical isolation via optical coupling between input and output circuits.
- Integrates an NPN phototransistor for reliable signal transmission in low-power applications.
- Utilizes a compact SOP-4 surface-mount package suitable for automated assembly processes.
Applications
- Industrial control systems requiring signal isolation
- Consumer electronics power supply feedback loops
- Microcontroller interface circuits for noise immunity
Procurement Notes
Verify the specific suffix -V-F3-A against official Renesas documentation to confirm pinout and packaging details. Confirm availability status as distribution data may indicate limited stock or end-of-life conditions. Ensure compliance with RoHS directives and check for any regional sales restrictions before procurement.
Selection Notes
Select this component when a 40 V collector-emitter voltage and 80 mA output current are sufficient for the load. The 3750 Vrms isolation rating suits applications demanding standard industrial safety standards. Consider the SOP-4 footprint constraints and verify that the 50 mA forward current requirement aligns with the driving circuit capabilities.
Part Context
This part belongs to the PS2701 series of transistor output optocouplers from Renesas. The series is designed for general-purpose isolation tasks. The PS2701-1-V-F3-A variant specifically denotes the SOP-4 package and specific testing criteria defined by the manufacturer's internal coding system for mass production units.
Replacement Considerations
Publicly confirmed substitute part numbers for this specific model were not found in the provided source material. Engineers should consult official Renesas cross-reference guides or datasheets for verified alternatives.
