Xiamen Hualian Semiconductor has launched multiple automotive grade optocouplers which include two mainstream categories: optical MOS solid-state Relays and transistor optocouplers. They have finished AEC-Q101 standard testing and certification, meeting the automotive grade harsh usage environment. These products are pin to pin replacements for the top brands from EU/US/Japan, covering working temperature of 125 ℃ with a long lifespan more than 15 years(@ attenuation ≤ 10%) and reaching the expected design failure rate of ppb level. These Hualian optocouplers ensure the high reliability and safety protection for new energy vehicles.

Hualian automotive transistor output optocouplers are used for EV main drive inverter, OBC, DC-DC and other components to achieve signal isolation feedback function. The products can work stably and durably under the working conditions of -55 ℃ to 125 ℃ with high parameter performance on a par with the same specifications of Bosco and Toshiba.
