What I didn’t know about npn transistors – mosfet driving

The holiday gave me a chance to play with bipolar transistor mosfet drivers again. And things did not go quite as planned. I had been using the circuit on the right quite happily from a signal ...

Test Setup Checks Transistors’ hFEs When Tight Control Is Important

This file type includes high resolution graphics and schematics. The spread of h FE values in a batch of transistors may be wide enough to cause unreliable performance during mass production of a ...

All About PNP Transistors

In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use NPN transistors. As [Aaron Danner] points out, many people think PNP transistors are “backward” but ...

What are transistors and thyristors?

A transistor is a key component in electronics, often used as a switch or to amplify a signal from a sensor. NPN (negative-positive-negative) transistors are the most used transistor. An illustration ...

Transistor testing costs are a ‘serious’ problem

The cost of testing a transistor will approach and may exceed the cost of manufacturing it, Professor Bashir Al-Hashimi at the University of Southampton, has warned. Al-Hashimi, who is at the ...
