The product is the TLP525G, TLP525G−2 and TLP525G−4 three models of photocouplers produced by TOSHIBA, with optical isolation, high voltage resistance, low impedance, high reliability and other features
The TLP525G family consists of GaAs infrared LED optically coupled to a photo‑triac. The TLP525G‑2 offers two isolated channels in an 8‑lead DIP package, while the TLP525G‑4 provides four isolated channels in a 16‑lead DIP package. The device is intended for general electronics applications such as computers, office equipment, and industrial robotics.
The document lists absolute maximum ratings, recommended operating conditions, and detailed electrical characteristics, including forward voltage, trigger LED current, isolation voltage, and on‑state/off‑state currents. It also contains safety and usage restrictions for the semiconductor device.
