Bjt reverse breakdown
WebProcedure: The ALM1000 hardware power supply limits the maximum voltage available to 5 volts. The emitter base reverse breakdown voltage of many transistors is larger than this. In the configuration shown, voltages between 4.5 volts and 9.5 volts ( CA- V peak to peak swing + external battery voltage ) can be measured. WebBJT will also suffer avalanche breakdown at high voltage Common base configuration with I E = 0 will undergo avalanche breakdown at BV CBO near breakdown voltage of collector-base junction Common emitter with I B = 0 will undergo breakdown at even lower voltage Caused by carriers with the same carrier type as the base being swept back
