PS2701-1Y-F3-A

Overview

The PS2701-1Y-F3-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 an insulation voltage of 3750 Vrms, ensuring robust electrical isolation between input and output circuits. Key electrical parameters include a collector-emitter voltage of 70 V, a maximum collector current of 30 mA, and a forward voltage of 1.2 V at a forward current of 5 mA. The 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 via optical coupling between input and output circuits
• Integrates an NPN phototransistor for reliable signal transmission in compact packages
• Features internal shielding to block external light interference and enhance stability

Applications

• Industrial control systems requiring circuit isolation
• Consumer electronics power supply feedback loops
• Signal transmission in noisy electromagnetic environments

Procurement Notes

Verify the specific suffix 'F3' against official Renesas documentation to confirm tape and reel packaging specifications. Confirm RoHS compliance status through the manufacturer's latest environmental declaration. Ensure the component matches the exact SOP-4 pinout requirements for your PCB layout. Cross-reference the datasheet revision history to validate parameter consistency before integration into production designs.

Selection Notes

Select this component when a single-channel isolation solution with moderate speed and high voltage rating is required. The SOP-4 package suits space-constrained applications compared to larger DIP options. Consider the 30 mA collector current limit for load driving capabilities. Evaluate the 3750 Vrms isolation rating against system safety standards. Compare performance metrics with alternative Renesas series if higher current or different isolation levels are needed.

Part Context

This part belongs to the PS2701A family of transistor output optocouplers from Renesas Electronics. The family is designed for general-purpose isolation applications in industrial and consumer markets. The PS2701-1Y-F3-A variant specifically denotes the SOP-4 surface mount configuration with defined electrical characteristics. It serves as a compact alternative to traditional through-hole optocouplers while maintaining similar functional performance.
