PS2701-1-F3-L-A

Overview

The PS2701-1-F3-L-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and utilizes SOP-4 surface mount packaging. The device provides an insulation voltage of 3750 Vrms, ensuring robust electrical isolation between input and output circuits. Key electrical parameters include a maximum collector-emitter voltage of 40 V, a maximum collector current of 80 mA, and a forward voltage of 1.1 V at a forward current of 50 mA. The current transfer ratio ranges from 50% to 300%, with a typical rise time of 3 µs.

Feature Summary

• Provides high-voltage electrical isolation via optical transmission between input and output circuits.
• Integrates an NPN phototransistor for reliable signal switching in low-power applications.
• Utilizes a compact SOP-4 surface mount package to support automated assembly processes.

Applications

• Industrial control systems requiring signal isolation
• Power supply feedback loops
• Microcontroller interface circuits

Procurement Notes

Verify the specific suffix F3-L-A against official Renesas documentation to confirm lead-free status and tape-and-reel packaging configuration. Confirm component availability as distribution channels may list obsolete or limited-stock variants. Ensure compliance with RoHS directives by checking the manufacturer's latest certification documents before procurement.

Selection Notes

Select this component when a single-channel isolation solution with moderate speed and standard voltage ratings is required. Compare the 40 V collector-emitter voltage and 80 mA collector current limits against circuit requirements. Evaluate the 3750 Vrms insulation rating against safety standards applicable to the target application environment.

Part Context

This component belongs to the PS2701 series of transistor output optocouplers designed for general-purpose isolation tasks.
