Transistor (also called transistor) is only a general term for three-pin amplifier devices in Chinese meaning. The triode we often say may be several devices.
It can be seen that although they are all called triodes, in fact, the expressions in English are very different. The term triode is actually a pictographic vocabulary unique to Chinese.
"Triode" (electronic triode) is the only English translation of "triode" in the English-Chinese dictionary. It is related to the first appearance of electronic triode, and is the item originally referred to by the word triode in the true sense. The rest of the devices called triodes in Chinese cannot be translated into Triodes in actual translation.
Electronic triode Triode (commonly known as a kind of electronic tube)
Bipolar Junction Transistor BJT (Bipolar Junction Transistor)
J-type field effect transistor Junction gate FET (Field Effect Transistor)
Metal Oxide Semiconductor Field Effect Transistor MOS FET (Metal Oxide Semi-Conductor Field Effect Transistor) English full name
V-groove field effect transistor VMOS (Vertical Metal Oxide Semiconductor)
Note: These three seem to be field effect transistors. In fact, metal oxide semiconductor field effect transistors and V-groove channel field effect transistors are unipolar (Unipolar) structures, which correspond to bipolar (Bipolar), so It can also be collectively referred to as a unipolar transistor (Unipolar Junction Transistor).
Among them, the J-type field effect transistor is a non-insulating type field effect transistor, and the MOS FET and VMOS are both insulating type field effect transistors.
VMOS is a new type of power transistor with high current and high magnification (cross-channel) improved on the basis of MOS. The difference is that it uses a V-shaped groove, which greatly improves the amplification factor and working current of the MOS tube, but it also greatly increases. It is a high-power improved product of MOS tube, but the structure has been greatly different from the traditional MOS. VMOS has only enhancement mode and no depletion mode MOS tube unique to MOS.
