ON Semiconductor high power industrial applications such as solar inverters, uninterruptible power supplies (UPS), and motor drives demand a gate driver optocoupler capable of handling networks greater than 690 VAC and constant DC voltages greater than 1,000 VDC. Using ON Semiconductor's Optoplanar packaging technology and optimized IC design, the FOD8320 optocoupler achieves reliable and high insulation voltage, as well as high noise immunity. The device, housed in a wide-body, 5-pin small outline package, offers a compact footprint while allowing for a creepage and clearance distance greater than 10 mm and 0.5 mm internal insulation distance. Additionally, the FOD8320 provides an extended industrial temperature range (-40 to +100°C) and is ideally suited for fast switching of power IGBTs and MOSFETs used in industrial inverter applications. Designed with 35 kV/µs minimum common mode noise rejection (CMR), resulting from the proprietary Optoplanar coplanar packaging technology, the FOD8320 eliminates the capacitive charge buildup that occurs in the over-under construction.
