PS2581L2-A

Overview

The PS2581L2-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics Corporation. It provides high isolation voltage of 5000Vrms between input and output circuits. The device features an NPN phototransistor output with a collector-emitter breakdown voltage of 80V and a maximum DC forward current of 80mA. It operates within a temperature range of -55°C to 100°C and is housed in a 4-DIP package.

Feature Summary

Provides electrical isolation via optical transmission between input LED and output transistor
Features high insulation voltage capability for noise immunity
Utilizes through-hole mounting for robust mechanical connection

Applications

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

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm pinout and packaging variations. Confirm RoHS compliance status as per the latest datasheet revision. Check component availability status, as some variants may be marked as not recommended for new designs. Ensure sourcing from authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component when high isolation voltage is required for single-channel applications. Consider the 80V output voltage rating and 80mA forward current limits during circuit design. Evaluate the DIP package constraints for PCB layout. Compare CTR specifications if precise gain requirements exist for the application.

Part Context

This part belongs to the PS2581 series of long creepage high isolation voltage photocouplers. The series includes variants with different output configurations and packaging options. Renesas Electronics acquired NEC's semiconductor business, continuing production of these legacy components under the Renesas brand.
