Overview
The PS2701-1-V-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics, originally developed by NEC. It features an NPN phototransistor output and is housed in a lead-free plastic SOP-4 package. The device provides high isolation voltage of 3750 Vrms and supports a maximum collector-emitter voltage of 40 V. It operates within a temperature range of -55 °C to +100 °C with a nominal current transfer ratio of 100%.
Feature Summary
- Provides high electrical isolation between input and output circuits
- Utilizes a compact surface-mount SOP-4 package for efficient board space utilization
- Features robust thermal performance suitable for wide industrial temperature ranges
Applications
- Industrial control systems requiring signal isolation
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the component status carefully as this part may be classified as Not Recommended for New Designs (NRND) or discontinued by the manufacturer. Confirm availability through authorized distributors and ensure that any alternative sourcing meets original specifications. Check RoHS compliance details and verify the specific suffix indicates lead-free construction before procurement.
Selection Notes
Select this component when a single-channel transistor output optocoupler with 3750 Vrms isolation is required. Ensure the circuit design accommodates the 40 V collector-emitter voltage limit and the 50 mA maximum forward current. Consider the SOP-4 package constraints for PCB layout and verify that the operating temperature range aligns with the application environment requirements.
Part Context
This component belongs to the NEPOC series of high isolation voltage multi-photocouplers produced by Renesas Electronics. The series is designed for applications demanding reliable galvanic isolation in compact form factors. The PS2701-1-V-A specifically represents the single-channel variant within this family, offering standardized performance metrics for general-purpose isolation tasks.
Replacement Considerations
Consult official cross-reference data for direct substitutes. Verify compatibility regarding pinout, isolation voltage, and package dimensions if considering alternatives from other manufacturers.
