PS2581AL2-W-A

Overview

The PS2581AL2-W-A is a single-channel transistor output optocoupler manufactured by CEL. It integrates a GaAs infrared emitting diode and an NPN silicon phototransistor within a surface-mount package. The device provides high isolation voltage of 5000 Vrms between input and output circuits. Key electrical parameters include a collector-emitter breakdown voltage of 70 V, maximum forward current of 30 mA, and typical switching times of 3 µs rise and 5 µs fall. It operates within a temperature range of -55 °C to +100 °C.

Feature Summary

High isolation voltage capability for safe signal transmission across potential barriers
Surface-mount Gull-wing package design for automated assembly integration
Long creepage and clearance distances to enhance safety compliance

Applications

Industrial control systems requiring galvanic isolation
Signal transmission in noisy electrical environments
Microprocessor interface circuits for level shifting

Procurement Notes

Verify the specific manufacturer source, as this component is produced by both CEL and Renesas Electronics under similar part numbers. Confirm that the datasheet matches the exact suffix requirements for your application. Check for RoHS compliance status and ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when a surface-mount solution with high isolation voltage is required. Ensure the circuit design accommodates the NPN phototransistor output characteristics. Verify that the operating temperature range meets the environmental conditions of the final assembly. Consider the physical footprint constraints of the SMD package during PCB layout.

Part Context

This component belongs to the NEPOC series of optocouplers, designed for cost-effective isolation solutions. The PS2581AL2 variant specifically features a lead-bending configuration suitable for surface mounting. It serves as a standard replacement for through-hole DIP versions in modern compact electronic designs requiring reliable signal coupling.
