Hello, Welcome to Dasenic

The TIL195B is a photoelectric isolator, also known as an optocoupler or optoisolator, designed to transfer electrical signals by using light waves to provide electrical isolation between input and output circuits. It consists of an infrared LED and a silicon phototransistor packaged in a dual in-line chip. This component is widely used in various electronic applications where galvanic isolation is required to prevent noise or ground loop interference. Functions: The TIL195B isolator functions by converting electrical signals into light signals using an LED, which are then detected and converted back to electrical signals by a photosensitive transistor. This mechanism ensures that signals are transmitted across the isolation barrier without any direct electrical connection between two circuits. Applications: - Signal isolation in power supplies - Industrial control systems - Medical equipment - Motor drives - Isolation of serial communication interfaces Alternative Components: - TLP2200: High-speed optocoupler from Toshiba - SFH6770: Optocoupler with increased LED current transfer ratio from Infineon - IL715: High-speed optocoupler from Vishay Embedded Modules: - TLP292-4: High-speed, high-isolation voltage optocoupler module from Toshiba - ACPL-M61L: Isolated gate driver module from Broadcom - HCPL-7800A: Precision optocoupler module from Broadcom Related Q&A: 1.
