Photocoupler Transistor, Photovoltaic Output TLP281 SOP4 marking P281
TLP281 is a 4-pin SOP photocoupler manufactured by Toshiba. It is an optically isolated output type photocoupler that uses a GaAAs LED on the input side and a phototransistor on the output side. Description: The TLP281 is a 4-pin SOP photocoupler that provides electrical isolation between input and output. It is designed to provide a high degree of isolation between input and output, with a minimum isolation voltage of 5,000 Vrms. The TLP281 is designed to provide a high degree of noise immunity, with a maximum propagation delay of 4.5 μs. Features: 4-pin SOP package Optically isolated output type photocoupler GaAAs LED on the input side Phototransistor on the output side Minimum isolation voltage of 5,000 Vrms Maximum propagation delay of 4.5 μs High degree of noise immunity Applications: The TLP281 is suitable for a wide range of applications, including industrial equipment, home appliances, office automation equipment, and other applications requiring electrical isolation. It can be used in applications such as motor control, power supply control, and signal transmission. (For reference only)
