Stock Quantity: 0
The TLP181GB is a surface-mount photocoupler manufactured by TOSHIBA. This device integrates an infrared emitting diode (IRED) and a phototransistor, providing electrical isolation between the input and output circuits. Its compact package makes it suitable for high-density board designs requiring signal transfer with galvanic isolation.
This photocoupler is commonly used in applications requiring signal isolation and noise reduction. Its design allows for safe and reliable data transmission between circuits with differing voltage levels or ground potentials.
