Overview
The PS2701-1-P-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and utilizes a SOP-4 surface-mount package. The device provides a high isolation voltage of 3750 Vrms. Key electrical parameters include a collector-emitter saturation voltage of 300 mV maximum, a forward current of 50 mA, and a forward voltage of 1.1 V. The current transfer ratio ranges from 50% to 300%, with a typical rise time of 3 μs.
Feature Summary
- High isolation voltage capability for safe signal transmission between isolated circuits
- Compact SOP-4 surface-mount package design for space-constrained applications
- Fast switching performance with a typical rise time of 3 microseconds
Applications
- General-purpose signal isolation in industrial control systems
- Interface circuits for microcontrollers requiring galvanic isolation
- Power supply feedback loops for voltage regulation
Procurement Notes
Verify the specific suffix -P-A against the official Renesas datasheet to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status as indicated in the product attributes. Check the lifecycle status, as related PS2701 variants may be marked NRND (Not Recommended for New Designs). Ensure the ordering part number matches the exact pinout and packaging requirements for your PCB assembly process.
Selection Notes
Select this component when a single-channel isolation solution with high voltage withstand capability is required. The SOP-4 package suits automated surface-mount assembly. Consider the 50 mA forward current rating for LED drive requirements. Verify that the 3750 Vrms isolation voltage meets the safety standards of the target application environment compared to lower-rated alternatives.
Part Context
This component belongs to the PS2701 series of optocouplers from Renesas Electronics. The series typically includes variations with different suffixes indicating package types or packaging formats. The PS2701-1 variant specifically denotes a single-channel configuration with an NPN phototransistor output, distinguishing it from dual-channel or other output types within the broader family.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult the manufacturer's official substitution guide or contact Renesas support for verified equivalents.
