Mini tesla coil transistor heating. 0. Apr 14, 2025 · Originally invented by Nikola Tesla, these coils demonstrate the principles of resonance and wireless energy transmission. In this article, we explore how to build a Mini Tesla Coil using a BD243 transistor. They can handle more current. . Feb 22, 2017 · If first try doesn’t work, interchange the two ends of the primary coil (the one with low number of turns), connect it and then try giving excitation to the circuit. As for how not to burn up your transistor, it is important that the secondary coil remain coupled to the primary coil and that the primary coil is connected such that the emf induced in the secondary shuts off the transistor. The important missing LED protects this from happening. Jul 25, 2018 · I am trying to made a mini tesla coil with d882 transistor. I'm not familiar with tesla coils but I'm assuming this thing requires a good chunk of current to function? If so, you are burning the BJT by operating in linear mode rather than saturation, latter which is for getting the most current through your transistor. 3mm cupper wire (300 turns), 4 batterys 1. This worked exceptionally well, and I haven't killed any transistors since then! Now, I even get plasma shooting out the end! If you decide to build this, use that configuration, but use more powerful transistors, like 2N2222's or 2N4401's. 5v to make a 6v power supply, 22k resistor and a light bulb for testing. When I connect everything together, the d882 transistor become very hot, so I guess it still working. Sep 26, 2021 · When the maximum-allowed emitter-base voltage of a transistor is exceeded then the transistor is ruined. cycyd siemduv zumqg jxgt yzaalm obunpf uejys rnaove atmq afberm
