Toshiba Semiconductor and Storage TLP350(F) Environmental and export classification status description

The Toshiba TLP350(F) is an opto-isolator that consists of a GaAs (Gallium Arsenide) infrared LED and a photodiode that are integrated into a single package. It provides electrical isolation between its input and output, making it useful for various electronic applications where signal integrity and safety are paramount. Functions - Signal Isolation: It separates voltage levels between the input and output, protecting sensitive components from high-voltage spikes. - Signal Transfer: Allows the transfer of information through light, with a low threshold voltage and fast response time. - High Noise Immunity: Reduces noise susceptibility thanks to its isolation properties. Applications - Switching Power Supplies: Used to transfer feedback signals while maintaining electrical isolation. - Microcontroller Interfaces: Often employed in interfacing microcontrollers or processors with high-voltage components, sensors, or actuators. - Telecommunication Systems: Ideal for isolating signals in communication systems to prevent noise interference. - Industrial Automation: Involves isolating and interfacing sensors and actuators from control circuitry for safety. Alternative Parts 1. Texas Instruments ISO121: An isolated data transmitter for digital signals. 2. Broadcom H11AA1: Another option for opto-isolators with similar functionality. 3. FLUKE 117: Multi-purpose isolated digital multimeter (not a direct substitute but for applications requiring isolation). 4. Easton Opto-ISOLATORS: Various models that serve similar purposes in isolation applications.
