SL5583W

Overview

The SL5583W is a single-channel phototransistor output optocoupler manufactured by Fairchild Semiconductor, now part of onsemi. It features a wide-body 6-pin DIP-B package designed for high isolation applications. The device provides an isolation voltage rating of 5300 Vrms between the input LED and output phototransistor. It incorporates a base pin to facilitate faster switching speeds and improved linearity compared to standard phototransistor outputs. The component utilizes infrared transmission technology for signal coupling.

Feature Summary

• High isolation voltage capability suitable for demanding industrial environments
• Integrated base terminal allows for external control of switching speed and sensitivity
• Wide-body encapsulation design ensures enhanced creepage and clearance distances

Applications

• Industrial automation control systems requiring galvanic isolation
• Power supply feedback loops for safety isolation
• Solid-state relay driver circuits

Procurement Notes

Verify the manufacturer marking as onsemi, following the acquisition of Fairchild Semiconductor. Confirm the package type is the specific wide-body 6-DIP variant. Check datasheet revisions for updated electrical characteristics. Ensure compliance with current RoHS directives if required for the application. Validate authenticity through authorized distribution channels.

Selection Notes

Select this component when high isolation voltage and fast response time are critical. The base pin feature distinguishes it from standard optocouplers by allowing user-adjustable performance. Consider the wide-body package for PCB layouts requiring strict safety spacing standards. Evaluate thermal dissipation requirements based on the forward current specifications in the official datasheet.

Part Context

This device belongs to the SL558x series of phototransistor optocouplers. It shares architectural similarities with the SL5582W but differs in specific electrical ratings or packaging nuances defined by the manufacturer. The series is characterized by robust isolation capabilities and is widely used in legacy and modern industrial designs requiring reliable signal transfer across potential barriers.

Replacement Considerations

Direct substitutes include the SL5582W, which shares the same family architecture and package style. Verify pinout compatibility and isolation voltage ratings before substitution. Cross-reference with other wide-body DIP optocouplers from onsemi or equivalent manufacturers ensuring matching CTR and switching speed parameters.
