The reliability tests of automotive grade optocouplers are more rigorous than traditional universal optocouplers to ensure higher quality and reliability. Hualian automotive grade Optocouplers have completed AEC-Q101 standard testing and certification, which meet the harsh usage environment of automotive grade.

Hualian provides a complete range of automotive-grade optocouplers such as optical MOS relays/transistors, which are widely used for I/O interfaces, feedback circuits, and BMS systems. The products are PIN to PIN replacements of the TOP brands from EU, US and Japan, covering an operating temperature of 125°C with a lifetime more than 15 years (@ attenuation ≤ 10%), and reaching the expected design failure rate of PPB level, which protects the high reliability and safety of new energy vehicles.
