Hualian Photo MOS relays have many advantages such as contactless lifespan, fast response, less installation space, low driving current, etc. They are used as high and low voltage switches for grounding insulation detection and voltage monitoring in power battery BMS. Among them, the optical MOS relay HSSR-61A0D-2 (alternative for AQV258) , packaged in DIP5/SMD5, has an over 1500V output insulation voltage and strong robustness, which is suitable for 400-600V new energy vehicle platforms. The Photo MOS relay HSSR-16S1A0D (alternative for ASSR-601J/QCPL-A58J), packaged in SO-16, has a load voltage of up to 1800V at the output end and a load withstand voltage test capability of over 3000V. It has higher resistance to overvoltage breakdown, higher safety standards and a wider operating temperature range than those top brands such as Panasonic Broadcom, etc, it’s suitable for new energy vehicles on platforms above 800V. At present, Hualian Automotive Standard Photo MOS Relays have been widely used in the vehicle and energy storage industry. With excellent performance, innovation and industrial value, our products won the first prize in the "2022 New Energy Vehicle Technology (Advanced Electric Drive) Innovation Rally" held by the National New Energy Vehicle Technology Innovation Center (National Innovation Center).
