Technical Article Selection and Proper Operation of Switching Power Transistors: Part 2 June 23, 2020 by Artur Seibt With 3 materials and about 8 types of transistors to select from — although not all combinations are available — the choice of the optimum switching transistor is difficult.

But, because BC517 is a darlington transistor, it has a huge gain (hFE = 30,000), so you can easily switch on the transistor with a very small base current. If you chose to drive the base of the transistor with a 1KOhm resistor, you'll have a 3.6mA base current, which is sufficient for your purposes. So the winner would be the BC517. A transistor that is full on (with R CE = 0) is said to be ' saturated '. When a transistor is saturated the collector-emitter voltage V CE is reduced to almost 0V. When a transistor is saturated the collector current Ic is determined by the supply voltage and the external resistance in the collector circuit, not by the transistor's current gain.

When choosing the right transistor for this job, first I'll eliminate the PNP transistors. They're a bit more complicated to use in your case. As you said, for a PNP transistor, active high becomes active low, meaning the transistor will switch on when you apply 0V from your Arduino, but it won't switch off when you apply 5V from the Arduino. Selection Criteria.

Counter/Timer/Tachometer; Extremely bright, large LED indicator; 1 pre-select value with transistor output; PNP and Pre-selection, active at counter value ≤ 0.

Description.

There are two basic types of transistor - bipolar junction transistors and field-effect transistors, known respectively as BJTs and FETs. The most basic question of all when choosing a transistor, though, is not whether it's a BJT or an FET but its polarity - in use is its my friend later said that one can use a transistor which has got greater Vceo,Vcbo,Vebo,Ic,Hfe,Ft,PD watts, and also said it will affect the circuit. but the thing i didn't understand correctly is that " will the new higher power transistor affect in a bad way or in a good way,like the new Double bipolar transistors - Meeting the design challenges of the future A bountiful selection of double transistors ensures you can pick the best device for your design. For today’s increasingly efficient systems – where both power and space are at a premium – we offer SMD packages includes our ultra small leadless housing SOT883. IGBTs are encroaching upon the high frequency, high efficiency domain of power MOSFETs. The industry trend is for IGBTs to replace power MOSFETs except in very low current applications. In part 1 of this two-part article you will understand what IGBTs are, the tradeoffs and how to select one.
