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.

Scientists in the Middle East have developed a series active filter to improve power quality in grid-tied PV systems, consisting of an inductor, two capacitors, and four transistor-diode pairs ...

Recent enhancements to the classic BJT show that the classic transistor has plenty of life left and can challenge SiC and GaN devices in some power applications. By Burkhard Laue, Senior Principle ...

In addition to the BD679 transistor shown, many commonly available NPN power transistors can be used here – 2N3055, TIP3055, TIP41C, BD681, BD745, etc., or their handy drop-in replacements. Also, ...

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 ...

Open-circuit transistor Let’s refer to a PNP transistor (the results immediately generalize to an NPN transistor). In open circuit conditions, we expect behavior similar to that of a single junction, ...

Insulated Gate Bipolar Transistor (IGBT) may convey high current and sustain high breakdown voltages; it may provide high power control. In a sense, how IGBT demonstrates the capability of power ...

Check whether a given electronic components (e.g. diode, transistor or I C ) is in working order. 4. To observe refraction and lateral deviation of beam of light incident obliquely o glass slab. 5.
