Why an N-type MOSFET?
MOSFET (Metal-Oxide Semiconductor Field-Effect Transistor) is one of the most popular types of transistors used in electronics. It consists of a gate, a drain, a source, a semiconductor and an insulator (or N-channel space). Contacts are made to the drain and the source - between them there is a surface of the semiconductor covered with a thin surface of the insulator. These transistors operate using mainly the properties of N-type and P-type semiconductors. They are formed by mixing silicon with an element having one more valence electron (donors) - an N-type semiconductor is formed, or one less valence electron (acceptors) - a P-type semiconductor is formed. When atoms of an element having one more valence electron than in silicon (donors) are added to silicon, an N-type semiconductor is formed. The situation is similar when atoms of an element having one less valence electron (acceptors) are added to silicon - a P-type semiconductor is created. N MOSFETs are N-channel transistors - the substrate has admixtures of acceptors, while the drain and source have admixtures of donors.
What do we offer in this section?
In our N MOSFET offer we have a wide range of N-type transistors, mini switches and kits for testing electronic components. These devices are very versatile - they are able to recognize a wide range of different components and specify their properties. It is a very helpful tool for any electronics. If, for example, you have electronic components and you don't know what they are (for example, because the paint has washed away and you can't recognize them by shape), you will find out what they are and what their properties. If it is a resistor, you will get information about its resistance, and if it is a capacitor, you will find out what its capacity is. The devices are designed to recognize elements made in THT technology (for threaded assembly) and SMD (for surface assembly). They can recognize MOSFET transistors (with P and N channels), bipolar transistors (PNP and NPN) and such elements as resistors, capacitors or diodes. Some devices also have the function of a small rectangular signal generator, a PWM signal generator and a frequency meter.
In this category the main products are of course transistors. We have, among others, double SMD transistors (enclosed in SO-08 enclosure) - maximum drain current is 3.5 A, maximum voltage cannot exceed 20 V, resistance is about 0.1 Ω. There are also single SMD transistors available in packs of 5 pieces - maximum voltage for them is 30 V, current is 5 A, and resistance is only 0.029 Ω. In packs of 5 pieces we also offer models closed in SOT-223 (SMD) with a maximum drain current of 2 A, maximum voltage of 55 V, closed in MICRO3 (SMD) with a maximum drain current of 4.2 A, maximum voltage of 20 V and resistance of 0.045 Ω and closed in SOT-23 (SMD) with a maximum drain current of 1.2 A, maximum voltage of 20 V and resistance of 0.25 Ω. We also have transistors designed for threaded assembly (THT) - in TO-220 enclosure, with maximum drain current 9.7 A, maximum voltage 100 V and resistance 0.2 Ω, in TO-220 enclosure, with maximum drain current 26 A, maximum voltage 50 V and resistance 0.55 Ω and 10 each in TO92 enclosures with maximum drain current 0.2 A, maximum voltage 60 V and resistance 9 Ω.5 each in TO-220 enclosures with a maximum drain current of 41 A, a maximum voltage of 55 V and a resistance of 0,0175 Ω, 5 each in TO-220 enclosures with a maximum drain current of 22 A, a maximum voltage of 100 V and a resistance of 0,055 Ω5 pieces each with a maximum drain current of 36 A, a maximum voltage of 100 V and a resistance of 0,044 Ω and 5 pieces each with a maximum drain current of 47 A, a maximum voltage of 55 V and a resistance of 0,022 Ω.
