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. The commonly used packaging forms for transistors include metal packaging and plastic packaging, and the arrangement of pins has a certain pattern 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.

According to the different structures and working principles, transistors can be divided into two types: NPN type and PNP type. 10pcs Original Genuine 104r5nt Svg104r5nt To-220 Set 10PCS-20PCS 104R5NT SVG104R5NT TO-220 120A/100V In Stock 10pcs Original Genuine 104r5nt Svg104r5nt To-220 Replacement Each of our packages is packaged in a reliable and secure manner. There are multiple manufacturers for individual electronic component models, and the production dates may also vary. Triode is one of the basic semiconductor components, which has the function of current amplification and is the core component of electronic circuits. Transistor, also known as bipolar transistor or crystal transistor, is a semiconductor device that controls current. There are two types of arrangements: PNP and NPN.
