Transistors are three terminal active devices made from different semiconductor materials that can act as either an insulator or a conductor by the … WebJunction Breakdown - BJT has two diodes back-to-back. Each diode has a breakdown. The diode (BE) with higher doping concentrations has the lower breakdown voltage (5 to 10 V). In forward active region, BC junction is reverse biased. In cut-off region, BE and BC are both reverse biased. The transistor must withstand these reverse bias voltages.
