he model and specifications are the same as those written in the title Each of our packages is packaged in a reliable and secure manner. Please carefully check for any goods upon receipt. If there is any damage during transportation, please contact me. There are multiple manufacturers for individual electronic component models, and the production dates may also vary. Therefore, the pictures we provide are for reference only. The commonly used packaging forms for transistors include metal packaging and plastic packaging, and the arrangement of pins has a certain pattern 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.
