Ideal for automotive, industrial, consumer and computing applications, our Schottky rectifier portfolio in Clip-bonded FlatPower packages (CFP) meets the challenging demands of efficient and space-saving designs. CFP packages with high power capabilities offer a true alternative to SMA, with better thermal performance on a smaller footprint.
For many systems and specifically power conversion circuits, the planar Schottky barrier diode has been a design mainstay for a long time. However, planar diodes impose a trade-off in key performance characteristics such as forward voltage drop and leakage current. Similarly, in high frequency applications, traditional Schottky diodes are far from the ideal lossless and instantaneous rectifier solution we would love to use.
Our Trench Schottky rectifier family achieves a well-balanced trade-off between VF and IR. Compared to equivalent planar diodes, the Trench devices have a wider safe operating area. With robustness against thermal runaway, this makes them ideal in applications which experience higher ambient temperatures.
Despite its higher parasitic capacitance, the Trench Schottky rectifier provides another benefit. Due to its higher current density, it has a smaller effective junction capacitance compared to planar Schottky diodes. Therefore, Trench rectifiers have less stored charges (Qrr) and may be more suitable in high frequency applications.
