PS2581AL2-A

Overview

The PS2581AL2-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics Corporation. It provides 5000Vrms isolation voltage between input and output circuits. The device features an NPN phototransistor output with a maximum collector-emitter voltage of 70V and a collector current rating of 30mA. It operates within a temperature range of -55°C to 100°C and utilizes a 4-DIP package for through-hole mounting.

Feature Summary

• Provides high isolation voltage capability for circuit protection
• Features fast switching performance suitable for digital signal transmission
• Includes UL and VDE approvals for safety compliance

Applications

• Industrial control systems requiring galvanic isolation
• Communication equipment interface circuits
• Power supply feedback loops

Procurement Notes

Verify the specific suffix 'A' against official Renesas documentation to confirm pinout and electrical tolerances. Confirm RoHS3 compliance status as per the latest datasheet revision. Check component availability status, as this part may be designated as not recommended for new designs in certain regions or channels.

Selection Notes

Select this component when high isolation voltage and compact DIP packaging are required. Ensure the 30mA output current capacity meets load requirements. Verify that the 70V collector-emitter voltage rating exceeds the maximum operating voltage of the driven circuit to prevent breakdown.

Part Context

This component belongs to the PS2581 series of long creepage high isolation voltage photocouplers. It is part of Renesas' NEPOC family, designed for applications demanding robust electrical isolation and reliable signal transmission in noisy environments.
