WebCJ is the junction small signal capacitance of the diode at a specified reverse voltage. Normally, CJ is a monotonically decreasing function of VR, as can be seen in the diode datasheet figure entitled “Junction Capacitance vs. Reverse Voltage.” With SiC diodes at high voltages, the capacitance will become constant, independent of voltage. WebMay 20, 2024 · 31,656. May 20, 2024. #3. From Wikipedia: The most important difference between the p-n diode and the Schottky diode is the reverse recovery time (trr), when the diode switches from the conducting to the non-conducting state. In a p–n diode, the reverse recovery time can be in the order of several microseconds to less than 100 ns for fast …
