TLP283,TLP283-4 is a photocoupler produced by TOSHIBA. This product is suitable for surface mount assembly and is used in applications such as board-mounted power supplies and programmable controllers.
The TLP283 and TLP283-4 are compact GaAs infrared LED and phototransistor optocouplers intended for surface‑mount use in power supplies, programmable controllers and other electronic equipment. The device consists of a gallium‑arsenide infrared emitting diode optically coupled to a phototransistor, providing electrical isolation between input and output circuits.
Key electrical characteristics include a collector‑emitter voltage rating of 100 V (minimum), a current transfer ratio of at least 100 %, and an isolation voltage of 2500 Vrms (minimum). Absolute maximum ratings, typical forward voltage, reverse current, capacitance and switching times are detailed, along with recommended operating temperature ranges of –55 °C to 100 °C. The datasheet also lists handling precautions and restrictions on product use.
