"Witryna10 lut 2024 · The second term is junctions. Every BJT has two P-N junctions called the Emitter-Base junction (EB) and the Collector-Base Junction (CB). Depending on the biasing of these two junctions, the BJT can operate in different modes. BJT, why should you be named the better transistor? " - Improve bjt second breakdown

The collector- emitter breakdown voltage, BVcer, is the main limiting factor in the design of a high-voltage driver. This breakdown voltage is a function of the total base resistance, RB, to the ac ground.

WitrynaFor a relatively thick base,the current gain will be relatively small.so it is increase the gain.Monolithicesigns for darlington connected BJT pair have been deveploed. Secondary Breakdown . Secondary breakdown is due to large power disspation at localized site within the semi conductor. Physics Of BJT Operation WitrynaSecond breakdown is an irreversible failure mode in bipolar power transistors. In a power transistor with a large junction area, under certain conditions of current and voltage, the current concentrates in a single area of the base-emitter junction. This current contraction effect causes local heating and destruction of the transistor.
