The TLP525G, −2 and −4 are TOSHIBA photocouplers consisting of a phototransistor and gallium arsenide infrared emitting diode. They can be used as triac drivers, featuring high isolation voltage and high response speed.
The TLP525G series are solid‑state relay (photocoupler) devices that combine a gallium‑arsenide infrared LED with a photo‑triac. The TLP525G‑2 offers two isolated channels in an eight‑lead plastic DIP package, while the TLP525G‑4 provides four isolated channels in a sixteen‑lead DIP package. These components are intended for general electronics applications such as computers, office equipment, and industrial robotics.
Key electrical ratings include a peak off‑stage voltage of 400 V (min), isolation voltage of 2500 V (min), forward LED current typical 20 mA, and a supply voltage rating of 120 VAC. The devices operate over a temperature range of –40 °C to 100 °C and feature a peak on‑state current capability of up to 2 A (100 µs pulse).
