Overview
The PS2701A-1-V-F3-P-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output housed in a 4-pin SOP package. Key electrical specifications include a maximum collector-emitter voltage of 70 V, a maximum collector current of 30 mA, and an isolation voltage of 3750 Vrms. The device supports a forward current of 5 mA with a forward voltage of 1.2 V. Current transfer ratio ranges from 50% to 300%, with typical rise and fall times of 5 μs and 7 μs respectively.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Utilizes a compact surface-mount SOP-4 package for automated assembly
- Delivers fast switching performance suitable for digital signal transmission
Applications
- Industrial control systems requiring signal isolation
- Measurement equipment input stages
- Power supply feedback loops
Procurement Notes
Verify the specific suffix -V-F3-P-A against official Renesas documentation to confirm pinout and tape-and-reel specifications. Confirm RoHS compliance status through the manufacturer's latest datasheet. Ensure design-in approval prior to procurement as component availability may vary.
Selection Notes
Select this component when 3750 Vrms isolation is required in a small footprint. Compare the 70 V collector-emitter voltage rating against circuit requirements. Evaluate the 50-300% CTR range for logic level compatibility. Consider the SOP-4 package dimensions for PCB layout constraints.
Part Context
This part belongs to the PS2701A series of single-channel optocouplers. It shares the core phototransistor architecture with variants differing in packaging or reel specifications. The series is designed for general-purpose isolation applications where moderate speed and high isolation voltage are prioritized.
Replacement Considerations
Consult Renesas official substitution guides for direct replacements. Verify pin compatibility and electrical parameters before integrating alternative components.
