Web1. Selecting MOSFETs MOSFETs with appropriate ratings and characteristics should be selected according to the applications in which they will be used. 1.1. Voltage and Current Ratings The drain -source voltage V DSS rating is important in selecting MOSFETs. Application of a voltage exceeding V DSS might result in the destruction of a MOSFET. WebApart from nominal capacitance, the voltage rating is the second most important parameter that must be essentially factored in. The capacitor’s voltage rating should always be at least 1.5 times or twice the maximum voltage it may encounter in the circuit. Capacitors are not as reliable as resistors.
