WebReverse-Blocking Mode When a negative voltage is applied across the collector-to-emitter terminal shown in Figure 1, the junction J1 becomes reverse-biased and its depletion layer extends into the N--drift region. The break down voltage during the reverse-blocking is determined by an open-base BJT formed by the P+ collector/ N--drift/P-base ... Weband with no bias on the gate, no channel is formed under the gate at the surface and the drain voltage is entirely supported by the reverse-biased body-drift p-n junction. Two related phenomena can occur in poorly designed and processed devices: punch-through and reach-through. Punch-through is observed when the depletion region on the source side
WebCRSS = small-signal reverse transfer capacitance. CISS = small-signal input capacitance with the drain and source terminals are shorted. COSS = small-signal output capacitance with the gate and source terminals are shorted. The MOSFET capacitances are non-linear as well as a function of the dc bias voltage. Figure 7a shows how WebJan 15, 2024 · Dynamic resistance of a p-n junction diode. The slope of the graph between current and voltage in a p-n junction diode, under both forward bias and under reverse bias, varies a lot on varying the voltage. Hence, given the graph, how do we decide which two points to take to calculate ΔV and ΔI in order to find r = Δ V / Δ I?
