![]() Moreover, the NSI82xx series is compatible with high-precision, high-speed and two-way digital isolators from other manufacturers, such as ISO78xx, ISO774x-Q1, and ACNT-H6xL, etc.ĭepending on applications, NSI82xx series are divided into two sub-series – NSI82xx-DSWWR and NSI82xx-Q1SWWR high-reliability, multichannel ultra-wide-body digital isolators. This makes this digital isolator series a perfect choice for photovoltaic facilities and other high-voltage systems having a high creepage distance requirement. They provide a long creepage distance of 15 mm, and an outstanding EMC property. NSI82xx digital isolators from NOVOSENSE are products in ultra-wide-body package. ![]() In photovoltaic systems for example, the creepage distance of isolator under 1500 V enhanced insulation condition shall be more than 14 mm, as required in IEC 62109. The creepage distance of the ultra-wide-body package is up to 15 mm, which can meet the safety requirements of customers’ high-voltage systems. Ultra-wide-body digital isolator is a highly reliable isolation product that features high electromagnetic immunity, low electromagnetic radiation and low power consumption, and can withstand higher isolation surge voltage. Actually, different manufacturers designate different names for ultra-wide-body packages. ![]() As a response, some wide-body (SOP) and even ultra-wide-body (DWW) packages emerged. This requires an isolator that provides a longer creepage distance to meet the voltage withstand and creepage distance requirements specified in China’s national standard GB4943.1-2022. To improve the power density of photovoltaic modules, the bus voltage has been increased to 1500 V. In photovoltaic applications, monocrystalline silicon and polycrystalline silicon materials are required. Ultra-wide-body package emerging at the right time It is widely used in photovoltaic systems, new energy vehicles, industrial automation systems, isolated SPI, RS232, RS485, general-purpose multi-channel isolation unit, and motor control. Digital isolator now has become one of the semiconductor devices that help unlock the huge potential of high-voltage applications. Wide bandgap (WBG) devices like SiC and driver products pose higher requirements for isolators while continuously improving the power density. To this end, many factors need to be taken into account, including isolation rating, creepage distance and electric clearance, common-mode transient immunity (CMTI), and electromagnetic interference (EMI). In high-voltage systems, a reliable isolation gate must be built using isolation means, which electrically isolates sensitive electronic components from fast transient high-voltage components to ensure power safety, better system performance and higher reliability. In this setting, high-voltage digital control applications pose growing isolation requirements, and the market sees a strong demand for high-efficiency and high-reliability digital isolators accordingly. 24, 2023 /PRNewswire/ - In recent years, the number of photovoltaic systems, chargers, new energy vehicles, energy storage facilities and other emerging technologies is increasing, and the installed base of industrial control devices, power supply, electricity and other conventional applications is still climbing.
