SL5504S

Overview

The SL5504S is a single-channel optoisolator manufactured by onsemi, featuring a transistor output with an accessible base terminal. It provides high isolation voltage of 5300Vrms and operates within a temperature range of -55°C to 100°C. The device utilizes a 6-SMD gull-wing package for surface mount installation. Key electrical specifications include a maximum collector-emitter saturation voltage of 400mV, a forward current of up to 100mA, and a typical switching time of 20µs turn-on and 50µs turn-off. The current transfer ratio ranges from 40% to 300% at a forward current of 10mA.

Feature Summary

• Provides galvanic isolation between input and output circuits using LED-to-transistor technology.
• Includes a dedicated base terminal on the phototransistor output for external biasing or control flexibility.
• Designed for surface-mount applications with a compact 6-SMD gull-wing footprint.

Applications

• Industrial automation control systems requiring signal isolation
• Power supply feedback loops for voltage regulation
• Microcontroller interface circuits for noise immunity

Procurement Notes

Verify component authenticity through authorized distributors due to availability constraints. Confirm package orientation and pinout compatibility during integration. Check for RoHS compliance documentation. Ensure storage conditions meet moisture sensitivity level requirements. Validate replacement options if the primary part is discontinued.

Selection Notes

Select this component when base access is required for the phototransistor output stage. Consider the 5300Vrms isolation rating for high-voltage separation needs. Evaluate the 100mA output current capability against load requirements. Assess the operating temperature range for environmental suitability. Compare switching speeds with application timing constraints.

Part Context

The SL5504S belongs to the SL5500 series of optoisolators from onsemi. This series offers various configurations including variants without base terminals. The component serves as a standard solution for digital signal isolation in electronic circuits. It complements other isolation devices in power management and communication interfaces.

Replacement Considerations

H11AV1SM is listed as a similar alternative part number by onsemi. Verify pinout compatibility and electrical parameter equivalence before substitution. Confirm package dimensions match the existing design layout. Review datasheet specifications for both components to ensure functional parity.
