Safe operating area for bipolar transistors

  title={Safe operating area for bipolar transistors},
  author={Santosh P. Gaur},
A mathematical model is utilized to predict the safe operating area (SOA) for proper circuit applications of bipolar transistors in the forward as well as reverse operating regions. Nonuniformity of the temperature within the transistor structure due to internal self-heating and the avalanche multiplication effect in the reverse operating region, which cause second breakdown failure, are taken into account. Steady-state electrical and time-dependent thermal problems are solved to establish… CONTINUE READING
