The TOSHIBA TLP665G is a triac photocoupler that consists of a GaAs infrared emitting diode and a phototriac in a six lead plastic DIP.
The TLP665G is a six‑lead DIP optocoupler that combines a gallium‑arsenide infrared emitting diode with a photo‑triac. It is intended for triac driver and solid‑state relay applications in office machines and household equipment. The device features a high isolation voltage and low trigger current, making it suitable for a variety of general‑electronics uses.
Key specifications include a minimum isolation voltage of 5000 V rms, a peak off‑state voltage of 400 V, a trigger LED current up to 10 mA, and an on‑state current up to 100 mA. The datasheet also provides detailed maximum ratings, electrical characteristics, and recommended operating conditions for designers. This manual is written in Chinese.
