TLP629 is a photocoupler produced by Toshiba. It consists of a photodiode and a photosensitive transistor, which can convert light signals into electrical signals. The device has a maximum input current of 150mA, a collector-emitter voltage of 55V, a minimum photoelectric transfer ratio of 25% (IF=20mA), and a maximum isolation voltage of 5000Vrms. It is suitable for applications with an AC input current of up to 150mA.
The TLP629 family consists of GaAs infrared emitting diode optocouplers with one (TLP629), two (TLP629‑2) or four (TLP629‑4) isolated channels. They are intended for office machines, telephone equipment and general electronics applications where isolation up to 5 kV rms is required.
The document lists absolute maximum ratings, recommended operating conditions, detailed electrical characteristics, switching performance and usage restrictions. It also includes pin‑out diagrams for the various DIP packages and safety notes for handling the GaAs components.
