These consist of the type of device that was detected, a schematic symbol with pin numbers, and some parameters depending on the detected device type. For a PNP/NPN transistor you get h FE, V BE, and ...

Here’s a blast from the past as we reprint our news from NYC’s 1961 IRE show—the first integrated logic circuits in TO-5 and TO-18 cans are being announced.

Figure 2. NPN transistor Source: A.K Karthikeyan/CC [SA] [3.0] The primary difference between PNP and NPN transistors is in their biasing and polarity of their operation. While NPN transistors require ...

Just like with NPN and PNP transistors, there are N-FETs and P-FETs. N-FETs are like NPN transistors – the gate pin needs to have higher voltage than the source pin for the FET to open.

This made me look at the turn-off specs for the npn (a 2N2222A) and, for the first time I can remember, I noticed that the turn-off test circuit in the data sheet used a negative drive to the base.

By far the largest market for tubes in the early 1960s was television sets, and most new tube models released during that decade were designed for TV use. A new tube family, Compactrons, was ...

NPN transistors have several significant and beneficial benefits, so they are widely used in ac conductors. However, let’s take a look at what you’ll need to consider while deciding between ...

Let us consider the two examples of NPN transistors - BC547A and PN2222A, shown in the images above. Based on the fabrication process the pin configuration will change and the details will be ...
