The main criteria for MOSFET selection are the power loss associated with the MOSFET (related to the overall efficiency of the SMPS) and the power-dissipation capability of the MOSFET (related to the maximum junction temperature and thermal performance of the package). This application note focuses...

When it comes to MOSFET datasheets, you have to know what you’re looking for. While certain parameters are obvious and explicit (BV DSS, R DS(ON), gate charge), others can be ambiguous at best (ID, SOA curves), while others can be downright useless at times (see: switching times)....
Two commercial SiC MOSFET power modules, Cree’s 1.2 kV/300 A and Rohm’s 1.2 kV/180 A, underwent a non-destructive testing (NDT) investigation at Aalborg University, Denmark. As shown in Figure 1, the NDT setup involved a high-voltage power supply charging a capacitor...
Understanding the Data Sheet: PowerMOS:Allmanufacturers of powerMOSFETs provide a data sheetfor every type produced. The purpose of the data sheet isprimarily to give an indication as to the capabilities of aparticular product. It is also useful for the purpose ofselecting device equivalents ...
___ Understanding Peak Source and Sink Current Parameters Mateo Begue, High Power Drivers Gate drivers are often confused as continuous current sources because of the IOH and IOL specifications in the datasheet. For example, designers looking at the UCC5320SC might read the parameters 4.3-A sourc...
The Qrr and Trr are intrinsic parameters of the diode during its turn-off phase and depend on the following parameters: 1. IF: Forward current flowing through the diode before it turns off 2. dI/dt: Slope applied to the diode and imposed by the circuit 3. Tj: Operating junction ...
To choose which transistor better suits your project, properly evaluate the key parameters of your project like budget, the switching speed required, the maximum voltage, and current ratings of the project. Based on these, one can then select the best employee (either MOS...
