Overview
The PS2701A-1-V-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and provides 3750 Vrms isolation voltage. Key electrical parameters include a collector-emitter voltage of 70 V, a maximum collector current of 30 mA, and a forward voltage of 1.4 V at a forward current of 30 mA. The device offers a minimum current transfer ratio of 50% and a maximum of 150%. It operates within a temperature range of -55°C to +100°C and has a power dissipation rating of 150 mW.
Feature Summary
- Provides high insulation voltage for safe signal transmission between isolated circuits
- Utilizes an NPN phototransistor output for reliable switching applications
- Operates across an extended industrial temperature range
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission in measurement and testing equipment
- Power supply feedback loops for circuit protection
Procurement Notes
Verify the specific suffix 'V' against the official datasheet to confirm package type and tape/reel specifications. Confirm RoHS compliance status as indicated in the manufacturer's documentation. Check for any lifecycle notices such as NRND or Obsolete status before finalizing procurement plans to ensure long-term availability.
Selection Notes
Select this component when a single channel with 3750 Vrms isolation is required. Ensure the 30 mA collector current limit meets the load requirements. Compare the 1.4 V forward voltage drop against available drive voltage sources. Verify that the SOP-4 package fits the PCB layout constraints.
Part Context
This part belongs to the PS2701A series of high-isolation voltage photocouplers from Renesas. The series is designed for applications demanding robust electrical isolation between input and output sides. The PS2701A-1 variant specifically denotes a single-channel configuration within this family.
Replacement Considerations
Consult the official Renesas cross-reference guide for verified substitutes. Ensure any replacement maintains the 3750 Vrms isolation rating and compatible pinout.
