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 V_AC and constant DC voltages greater than 1,000 V_DC. 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.
