WebA BJT is a 3-terminal semiconductor device, as the name suggests, the term bipolar is taken from the truth that this kind of transistor includes two kinds of semiconductor materials like P-type (positive type) and n-type (negative type) where the current flows from these regions Usually, these transistors include Silicon. WebIn a BJT, only a tiny portion of current flows is due to majority carriers, while most are due to minority charge carriers. As a result, they are referred to as minority carrier devices.
