As its name would imply, an I-V curve plots the device current of the device against a sweep of terminal voltage. Figure 2 shows an example of collector current as the collector-emitter voltage is changed, with a separate curve for di erent base currents. 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. herning iberia sl
