What is the difference between BJT and power BJT?

WebDerating Factor. The derating factor is defined as the scaling of the output power of the solar panel to consider the wire losses, losses due to dust particles, increased temperature, or any other thing that deviates the output power of the solar panel from the expected value.

"WebMar 2, 2006 · NPN bipolar junction transistor (BJT), and turning it on is definitely not part of normal operation. If the BJT were to turn on and saturate, it would result in a condition called latchup, where the MOSFET cannot be turned off except by externally interrupting the drain current. High power dissipation during latchup can destroy the device. " - Bjt power derating
