KEP40N26 TO-220 MOS Transistor 10 Slice Power MOSFET for Electronic Circuits

Transistor, also known as bipolar transistor or crystal transistor, is a semiconductor device that controls current. Its function is to amplify weak signals into electrical signals with larger amplitudes, and it is also used as a contactless switch. Triode is one of the basic semiconductor components, which has the function of current amplification and is the core component of electronic circuits. A transistor is a device that produces two PN junctions that are very close together on a semiconductor substrate. The two PN junctions divide the entire semiconductor into three parts, with the middle part being the base region and the two sides being the emitting and collecting regions. There are two types of arrangements: PNP and NPN.

• The model and specifications are the same as those written in the title
• According to the different structures and working principles, transistors can be divided into two types: NPN type and PNP type. The collector and emitter of NPN type transistors are both N-type semiconductors, while the base is P-type semiconductors; On the contrary, The collector and emitter of PNP type transistor are both P-type semiconductors, while the base is N-type semiconductors.
• The commonly used packaging forms for transistors include metal packaging and plastic packaging, and the arrangement of pins has a certain pattern
