WebTemperatures at the ruptured cell can increase to above 1,000°C (1,832°F). This rapid and extreme rise in temperature is termed thermal runaway and when it initiates the same reaction in adjacent cells it is known as thermal runaway propagation. When thermal runaway happens, it can produce smoke, fire and even explosions. WebVarying BJT biasing techniques provide specific characteristics, while others prevent thermal runaway.

What is thermal runaway in a BJT? - Answers

WebDec 15, 2024 · The thermal runaway takes place in a BJT. Thermal Runway in BJT is a process of self-damage of BJT because of overheating at the collector junction due to an increase in Ic with Ico; If T↑, then Ico (Reverse separation current) ↑, which results in an increase in the collector current, i.e. Ic ↑.
