Overview
The PS2701A-1-P-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates a GaAs infrared LED and an NPN silicon phototransistor within a 4-pin SOP package. Key electrical parameters include a collector-emitter breakdown 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 typical forward voltage of 1.2 V. It exhibits a minimum current transfer ratio of 50% and a maximum of 300%, with a rise time of 5 μs and a fall time of 7 μs.
Feature Summary
- High insulation voltage capability of 3750 Vrms for robust signal isolation
- Compact surface-mount SOP-4 package design suitable for space-constrained applications
- Integrated GaAs LED and NPN phototransistor for efficient optical coupling
Applications
- AC motor control systems requiring galvanic isolation
- Solid-state relay (SSR) driver circuits
- Microcontroller interface isolation in industrial automation
Procurement Notes
Verify the specific suffix 'P' against official Renesas documentation to confirm package variant details, as standard listings may reference generic SOP-4 configurations. Confirm RoHS compliance status through the manufacturer's certified datasheet. Ensure the component matches the required isolation voltage and CTR specifications for the target circuit design before procurement.
Selection Notes
Select this component when high isolation voltage and compact SMD packaging are required. Compare the 70 V collector-emitter voltage and 30 mA current limits against load requirements. Consider the 5 μs switching speed for timing-sensitive applications. Verify that the 5 mA forward current requirement aligns with the driving source capabilities.
Part Context
This part belongs to the PS2701A series of high-isolation optocouplers from Renesas. It is designed for cost-effective isolation in digital and analog signal transmission. The series typically offers various package options and electrical ratings to suit different industrial and consumer electronics applications requiring reliable signal transfer across isolation barriers.
Replacement Considerations
Consult official Renesas cross-reference documents for verified substitutes. Generic equivalents may differ in isolation voltage or CTR ranges. Ensure any replacement maintains the 4-pin SOP form factor and 3750 Vrms isolation rating.
