The TMBS electrical field distribution is close to that of a planar Schottky diode. This slide shows the capacitance of a Vishay TMBS and a planar Schottky with the same chip size. The junction capacitance of the 100 V TMBS is moderately larger than that of the planar Schottky rectifier for reverse-bias voltages over 30 V. However, since the TMBS technology has a higher current density, a smaller chip with lower capacitance may be used to offset this difference in a given application.
