PS2581L2-D-A

Overview

The PS2581L2-D-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and operates with a wide lead DIP-4 package. The device provides an isolation voltage of 5000 Vrms, ensuring robust electrical separation between input and output circuits. Key electrical parameters include a maximum collector-emitter voltage of 80V, a collector current of 50mA, and a saturation voltage of 300mV. The typical rise and fall times are 3µs and 5µs respectively, supporting standard switching speeds.

Feature Summary

Provides high-voltage electrical isolation for signal transmission
Utilizes an NPN phototransistor for reliable digital switching
Designed for through-hole mounting in standard DIP packages

Applications

Industrial control systems requiring galvanic isolation
Solid-state relay driver circuits
Microcontroller interface isolation

Procurement Notes

Verify component authenticity through authorized channels due to limited supply status. Confirm package variant matches design requirements as suffixes indicate specific packaging or lead configurations. Check latest datasheets for any recent manufacturing changes or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a single-channel transistor output isolator with 5000 Vrms rating is required. Ensure the 80V collector voltage and 50mA current capacity meet circuit load specifications. Verify that the DIP-4 footprint aligns with PCB layout constraints and that the switching speed is sufficient for the application frequency.

Part Context

This part belongs to the PS2581 series of optocouplers from Renesas Electronics. The series is designed for general-purpose isolation applications. The 'L2' designation typically indicates specific pin spacing or lead form variations within the DIP-4 family, while 'D-A' denotes the specific tape and reel or tube packaging configuration used for distribution.
