SF127A NPN Transistor

The SF127A is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the SF127A transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The SF127A transistor symbol shows an arrow from the base into the emitter. This means that the current flows from collector terminal to emitter terminal.

Circuit diagram symbol of the SF127A transistor as follows.
