Dec 21, 2022 · Thermal runaway can occur in any type of transistor, including bipolar transistors (BJTs) and field-effect transistors (FETs). In a bipolar transistor, thermal runaway is typically caused by high levels of collector current and in a field-effect transistor, it is caused by high levels of drain current.
May 25, 2024 · This article will look into what causes it, what happens when it occurs, and how to stop it. We will talk about the thermal runaway mechanism and ways to keep transistors in a safe operating area. Also, we will discuss effective heat dissipation techniques and current limiting methods.
If a MOSFET transistor produces more heat than the heatsink can dissipate, then thermal runaway can still destroy the transistors. This problem can be alleviated to a degree by lowering the thermal resistance between the transistor die and the heatsink.

Discover the intricacies of Thermal Runaway in Transistor Biasing and Design with this deep dive into Electronic Devices and Circuits - Part 1.
Thermal runaway is a phenomenon caused by the electro-thermal positive feedback widely observed in bipolar transistors with an excessive junction temperature rise. The origin of the thermal runaway (or thermal instability) is closely related to the positive temperature dependence of collector current I C , which increases with increasing ...
Aug 7, 2020 · This video explains the phenomenon called Thermal runaway, which is the self destruction of transistor due to excessive current flow through the collector. This phenomenon occurs due to...
Thermal runaway is a phenomenon that occurs in transistors and other semiconductor devices when their temperature rises uncontrollably due to excessive power dissipation. As the temperature increases, the device's electrical resistance decreases, leading to a higher current flow and even more power dissipation.
