What do we offer in this category?
The basic products in this category are single P MOSFET transistors made in THT and SMD technologies. We offer sets of five pieces for surface mounting and a choice between sets of 5 pieces and single transistors designed for threaded mounting. In our offer you will also find practical kits for testing and recognizing various types of electronic components. We can recognize mainly bipolar and unipolar transistors, diodes, resistors, capacitors and inductive elements. Thanks to a well thought-out design of the device, the user can test both THT and SMD components. The built-in LCD display shows detailed information about the type of element and its parameters. The device has dedicated stands for THT and SMD elements, is equipped with two buttons ("Test" and "Off") and is powered by a 9-volt 6F22 battery. The assortment includes several such products - some of them can additionally be used as a frequency meter or rectangular pulse or PWM signal generator. There are also executive modules with MOSFET transistors available from a well-known Polol company. Power supply voltages of such devices range from several to several dozen volts (depending on the model). These types of devices have protection against reverse voltage and are small in size, and if necessary they can connect several such elements together. In addition, thanks to a well-thought-out design, it is possible to set the option of switching off or controlling by means of external digital devices. However, it should be remembered that the switches have a limited voltage range - in the event of a power failure the state will be set to "off". It is also worth noting that the device does not provide full insulation when the "off" state is active: a small amount of current can still flow.
P MOSFET transistors
When atoms are added to silicon with an element having one more valence electron than in silicon (donors), an N-type semiconductor is formed. The situation is similar when atoms of the element having one less valence electron (acceptors) are added to silicon - then a P-type semiconductor will be formed. MOSFETs are transistors with a P-channel - the substrate has pots doped, while the drain and source have acceptors doped.
The use of MOSFET transistors
MOSFET transistors are best suited for systems with the lowest possible voltage. Their big advantage is very low resistance when the channel is open, thanks to which losses in this place are also very low. They need very little electricity for efficient operation and consume practically no power at the gate. They are usually used as amplifiers or switches, very often they are also used in microprocessors or so-called CMOS gates (Complementary Metal-Oxide Semiconductor). In student projects they can be used to switch on motors operating at higher voltage and to switch on LEDs. The high speed of switching states and high impedance described above are the reasons why such elements work perfectly well in many projects in the field of digital electronics.
MOSFET are resistant transistors
It is worth noting the durability of MOSFET transistors, which results from their construction. First of all, such elements are free from the so-called second puncture phenomenon. They are elements resistant to many unfavorable conditions, but it is worth to know their weaknesses. Before connecting, pay attention to the acceptable power of generated losses and the voltage and current of the collector - unfortunately, exceeding these values will most often result in permanent damage to the element. It is also very important to remember about the high sensitivity of MOSFET transistors to electrostatic charges - even a current with a potential difference of little more than 20 V can damage the element. Therefore it should be stored in a special conductive sponge in an antistatic cover. It is also good to discharge your body and the tools you will be carrying out the task with (soldering iron, tweezers and the like) before starting work. These are unique properties that may suggest the delicacy of such elements, but it is, among other things, the high durability that determines that they are so often used in many devices. It is enough to take appropriate precautions during assembly and selection of individual elements (taking care not to exceed the permissible values).
