Description: 
The static and dynamic electrical characterization of power Schottky rectifiers both with Ti and Ni2Si as Schottky metals having low negative coefficient of the breakdown voltage versus temperature will be presented in this paper. The values of the barrier height are respectively 1.28 eV and 1.68 eV, as extracted using the Tung’s model for inhomogeneous contacts from forward currentvoltage characteristics. These values were found to be in good agreement with those obtained by means of capacitance-voltage measurements. The breakdown voltage shows an almost linear dependence from the temperature for both types of devices. The extracted coefficients are respectively-0.08 V/C and-0.11 V/C, thus guarantying stable and reliable behaviour. Very short reverse recovery time at RT and at 125 C confirms the good thermal stability of these devices.
