PS2581AL2-E3-A

Overview

The PS2581AL2-E3-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics Corporation. It features an NPN phototransistor output and provides high isolation voltage of 5000 Vrms between input and output circuits. The device is housed in a lead-free plastic DIP-4 package, suitable for through-hole mounting. It operates within a temperature range of -55°C to +100°C and complies with RoHS3 standards. Key electrical characteristics include a collector-emitter breakdown voltage of 70V, a maximum forward current of 30mA, and a typical current transfer ratio ranging from 50% to 400% at 5mA input.

Feature Summary

Provides high-voltage electrical isolation via long creepage distance design
Features NPN phototransistor output for digital signal transmission
Complies with UL and VDE safety approval standards

Applications

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

Procurement Notes

Verify the specific suffix E3-A against official Renesas documentation to confirm lead-free status and packaging type. Confirm availability as this component may be subject to lifecycle changes. Ensure compatibility with existing PCB footprints and thermal requirements before procurement.

Selection Notes

Select this component when high isolation voltage and compact DIP-4 packaging are required. Consider the current transfer ratio range and switching speed specifications relative to the application's signal integrity needs. Verify that the operating temperature range meets the environmental conditions of the target system.

Part Context
