How to Connect Two or More Transistors in Parallel

Last Updated on June 3, 2026 by Swagatam 63 Comments

parallel

Connecting transistors in parallel is a process in which the identical pinouts of two or more transistors are connected together in a circuit in order to multiply the power handling capacity of the combined parallel transistor set. In this post I have explained how to safely connect multiple transistors in parallel, these can be BJTs […]
