Toshiba TLP126 Photocoupler Datasheet
The TLP126 is a miniature GaAs infrared optocoupler designed for surface‑mount assembly. It combines a photo‑transistor with an inverse‑parallel gallium arsenide LED, delivering high current transfer ratio (CTR) at low input current. The device is UL‑listed (UL1577) and offers a collector‑emitter voltage rating of 80 V.
The datasheet lists detailed maximum ratings, electrical characteristics, switching behavior, and recommended operating conditions. It also includes handling and safety restrictions for reliable use in general electronics applications such as computers, office equipment, and industrial robotics.
