SF127B NPN Transistor

The SF127B is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the SF127B transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The SF127B 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 SF127B transistor as follows.
