PS2381-1Y-V-F3-W-AX

Overview

The PS2381-1Y-V-F3-W-AX is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and operates with a maximum forward current of 5 mA and a forward voltage of 1.1 V. The device provides high isolation with a breakdown voltage of 5000 Vrms and supports collector-emitter voltages up to 80 V. It delivers a maximum collector current of 50 mA with a saturation voltage of 300 mV. Switching characteristics include a rise time of 4 µs and a fall time of 5 µs. The component is housed in a 4-pin LSOP package, suitable for surface mount applications.

Feature Summary

• High isolation voltage rating of 5000 Vrms for robust signal transmission across isolated circuits
• Wide operating ambient temperature range extending up to 115 °C for demanding environments
• Compact 4-pin LSOP surface mount package design facilitating automated assembly

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops for voltage regulation
• Signal interfacing between microcontrollers and high-voltage loads

Procurement Notes

Verify the specific suffix 'W' against official Renesas documentation to confirm packaging details, as distributor listings may vary. Confirm RoHS compliance status directly from the manufacturer datasheet before integration. Ensure the LSOP-4 footprint matches your PCB design constraints. Check for any recent lifecycle notices regarding this specific variant to avoid obsolescence risks during production planning.

Selection Notes

Select this component when high isolation voltage and wide temperature operation are critical. The NPN output type suits standard digital logic interfacing. Verify that the 50 mA collector current meets load requirements. Consider the 4 µs rise time for signal integrity in high-speed switching applications. Ensure the 5000 Vrms rating exceeds the system's isolation requirements for safety compliance.
