WebJFET : Junction Field-Effect Transistor (1) In the N-channel junction field-effect transistor (Fig. 3-3 (a)), when a voltage is applied between the drain and the source, electrons flow from the source to the drain. (2) When a reverse bias is applied between the gate and source, the depletion layer expands and suppresses the electron flow in (1).
WebFigure 2: Schematic cross-sectional view of SiC-JFETs to be separated with TLS, mounted on tape and frame and a view of process flow using TLS: 1. Removal of structures inside … WebThe novel approach is exemplified through a three device cascode Configuration, whereby a 5-20V silicon MOSFET blocks a lateral medium voltage 60-100V SiC JFET, which in turn reverse biases the gate of a vertical high voltage (≥1.2kV) SiC JFET. Furthermore, an elegant solution for the SiC part of the hybrid multiple cascode is also presented.
