SL5501W

Overview

The SL5501W 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 accepts a maximum DC forward current of 100 mA and delivers a peak output current of 100 mA. Key electrical parameters include a minimum current transfer ratio of 40% at 10 mA input, a typical turn-on time of 2 µs, and a maximum turn-off time of 50 µs. It is housed in a 6-DIP through-hole package.

Feature Summary

• Provides galvanic isolation between input and output circuits via an internal LED and phototransistor structure.
• Includes a dedicated base terminal on the output transistor to allow for external biasing or speed control adjustments.
• Designed for robust performance across wide industrial temperature ranges.

Applications

• General-purpose signal isolation in industrial control systems
• Microcontroller interface circuits requiring electrical separation
• Low-speed data transmission channels
