Triac output optocoupler encapsulates Aluminium Gallium Arsenide infrared light emitting diode optically coupled with photosensitive thyristor chip, The output end is divided into zero crossing bidirectional output and non zero crossing bidirectional output.

The products are widely used for industrial equipment market and home appliances like microwave ovens, washing machines, personal hygiene systems, refrigerators, fan heaters, induction heating pots, water heaters, etc. Hualian provides triac output optocouplers in different packages of SOP4, DIP5/SMD5, DIP6/SMD6, DIP7/SMD7, with the peak off-state voltage VDRM covering 400V, 600V, 800V, and the on-state effective current IT, The on-state peak voltage VDRM covers 400V, 600V, 800V. The on-state effective current IT (RMS) covers 100~1200mA, and the LED trigger current can be as low as 5mA.

Besides the common models in the market, Hualian also provides ultra-high Dv/Dt optocouplers (Dv/Dt≥4000V/us).
