To be honest, most of these circuits appear in interviews or textbooks to examine some people's understanding of triodes. But in the actual circuit, it is rare to see the triode working in the amplification area. Speaking of this, I also give reassurance to the college students in school. Every day in the textbook, "the collector is positively biased", and the "common collector and co-ejector" is very positive and that polar is reversed. To be honest, it is not very useful in work. If you do all these questions well, you will not be able to design an actual circuit; the engineer who designs the actual circuit may not necessarily be able to solve the problem.

Why Do Power Semiconductors Explode? The explosion of power semiconductor devices is generally in a short circuit state. The chip bears high voltage and high current at the same time, and the transient power loss is extremely large. When the short circuit state is too long (the driver is not well protected), the heat generated will break the chip (non-uniform internal stress) and the surrounding area in a short time. The material (surface aluminum layer, aluminum wire) vaporizes to produce an explosion.

A transistor is a semiconductor device used to amplify signals or act as an electrically controlled switch. A transistor is a three terminal device, a small current/voltage at one terminal (or lead) will control a large current between the other two terminals (leads). Transistors are essential components in almost all electronic circuits such as: amplifiers, switches, oscillators, voltage regulators, power supplies and most importantly digital logic ICs.
