TOSHIBA TLP541G, TLP542G is a photocoupler consisting of a photo-thyristor optically coupled to a gallium arsenide infrared emitting diode. It can be used to control isolated electrical circuits.
The Toshiba TLP541G and TLP542G are GaAs infrared emitting diode and photo‑thyristor optically coupled devices offered in six‑lead (TLP541G) and seven‑lead (TLP542G) plastic DIP packages. They are intended for general electronics applications such as computers, office equipment, measuring equipment, industrial robotics, and domestic appliances.
The document provides maximum ratings, recommended operating conditions, individual electrical characteristics, coupled characteristics, and usage restrictions. Key parameters include peak off‑state voltage, isolation voltage, forward and on‑state currents, and temperature limits.
