Xiamen Hualian Semiconductor has launched multiple automotive grade optocouplers, including two mainstream categories - Photo MOS solid-state relays and transistor optocouplers, all of which have passed AEC-Q101 certification, meeting the harsh usage environment of automotive grade. These products are pin to pin alternatives to top brands from EU,US and Japan, covering working temperature of 125 ℃ with long lifespan over 15 years (@ attenuation ≤ 10%) and reaching the expected design failure rate of ppb level, providing high reliability and safety protection for new energy vehicles.

Hualian PhotoMOS relays have many advantages such as contactless lifespan, fast response, less installation space, low driving current, etc. They are widely used for charging detection of DC/AC charging piles.
