How to design a transistor switching circuit
posted May 9 2011 20:20.42 by Giorgos Lazaridis

Almost daily, i get notifications for new theory video uploads from different youtube users. I really like seeing videos with good theoretic explanation of any kind, as it shows basically two things: First that the one who presents this theory has "done his homework" and second that he wants to share the knowledge. So usually, i am a "strict and quirky" judge.
But Ben Krasnow has certainly done his homework on switching transistors, and he feels like sharing it with you. I can only tell you that watching his video is a must. He explains in a very straight-forward way how can someone design a switching circuit using a transistor, to control high current loads such as a solenoid valve from a low current source like the output of a microcontroller. 10/10 for his teaching method and the clear-slow easy understanding accent. Good work Ben.

    • Use NPN as more as possible, unless use PNP. But always go for a NPN first

    • I love this. I had a lesson today on designing transistor switch and this video raised my interest in the topic. Now my question is when is the usage of PNP Transistor preferable?

    • hello sir,
      this is actually very helpful.
      well, i am doing a project and i too require a transister as a switch in my case the load under consideration is a piezo buzzer. I wanted to know whether the designing of this switch will be done the same way you did?
      please reply ASAP.
