In this article, we’re going to focus on using common bipolar junction transistors instead of relays ... more than sufficient in this case. Most NPN-type BJTs will work fine though.

The actual 3-component build uses a 10 farad supercapacitor as a power source, hooked up to a 2N3904 NPN transistor and an 85-turn coil. It won’t start oscillating on its own, but when triggered ...

Even this relatively simple circuit arrangement has subtleties that affect performance. In the crisp, clean, theoretical ...

Manufacturers sometimes (but not always) put switching time test results on their datasheets. Shown below are test circuits and test results for the 2N3904 NPN transistor. [6] From these test results ...

计算偏置电阻R1和R2的值，确保当发射极电阻R3设置为100 Ω时，NPN晶体管Q1中的集电极电流约为5 mA。假设电路由10 V电源供电。确保R1和R2之和（总电阻 ...

NPN Silicon Digital Transistor. Summary of Features. Switching in circuit, inverter, interface circuit, drive circuit. Built in bias resistor (R1 = 10 k Ω, R2 = 10 k ...

and Field Effect Transistors (FETs). BJTs are controlled by current, while FETs are controlled by voltage. Within these categories, there are further subdivisions such as NPN and PNP BJTs and ...

The first transistor was about half an inch high. That's mammoth by today's standards, when 7 million transistors can fit on a single computer chip. It was nevertheless an amazing piece of technology.

So What Was the Transistor Good For? Transistors may have been useful to the phone company and to a handful of scientists building computers, but that wasn't enough to build an industry.

A type of 3D FinFET transistor from Intel introduced in 2011 with its Ivy Bridge microarchitecture. The Tri-Gate design is considered 3D because the gate wraps around a raised source-to-drain ...
