Make It Simple

I have been working on this topic for a very long time. In Electronics, one of the main topics is Component selection.  How well circuits perform depends on how well components are selected. Component selection is a never-ending process. The component selection remains constant throughout the career. I am thinking of automating this component selection. This is my first step towards automation. And this is always an ongoing process. Below are the major components of electronics Bipolar Junction Transistor--> Invention which changed the world, so I want to start with that. MOSFET --> Metal Oxide Silicon Field Effect Transistor Resistor Capacitor Inductor Diode IGBT--> Insulated Gate Bipolar Transistor Op-Amp-->Operational amplifier MOV- Metal Oxide Varistor EMI filter TVS diode-->Transient Voltage Suppressor ADC chip Programmable diode Optocoupler Mosfet driver Zener diode Microcontroller Below is the link to the spreadsheet.

 The article which I have wanted to write for so long time. Actually, this is the topic that I completed and got deleted completely before publishing it. That is one of the tragic stories.  Ok, Back to the topic. I used to think that calculating thermal things was the most difficult thing in electronics because of the thermodynamics subject I studied during college. However, once I understand the logic behind the calculation, I feel that this is one of the easiest things in electronics. Just have to remember two formulas, that is, everything else is that derivation. The thermal resistance is given by `R_{\theta_{JA}}=\frac{T_{J}-T_{Amp}}{P_{D}}` ----(1) Also as per the resistance, the thermal resistance given by `R_{\theta_{JA}}= R_{\theta_{JC}}+R_{\theta_{CS}}+R_{\theta_{SA}}`    ---(2) Equating both equations we get, `\frac{T_{J}-T_{A}}{P_{D}}=R_{\theta_{JC}}+R_{\theta_{CS}}+R_{\theta_{SA}}` ---(3) The thermal resistance is expressed in  °C/W. That is, now I k...
