Two ignition Coils are connected in parallel but with opposite polarity. This next circuit is designed for a higher powered output. T2 represents two power transistors connected in parallel and mounted on a heatsink. RC1 is used to help suppress high voltage spikes that can destroy the power transistors. If you use a MOSFET or IGBT instead of a bipolar transistor like the 2n3055, you should also add a pulldown resistor of about 10k between the base/gate pin and GND. Further protection methods are outlined lower down this page and in the comments. Ones with higher voltage ratings will be less likely to be damaged by spikes. Pretty much any power transistor, IGBT or MOSFET can be used in this circuit as long as it is rated for at last 5A and 100V. While these are cheap and high temperature tolerant, they are susceptible to voltage spikes caused by the inductive nature of the load (ignition coil).
2n3055 transistor is it a mosfet driver#
