HLB121D NPN Transistor

The HLB121D is a bipolar junction transistor (BJT) with an NPN-type configuration. That means the HLB121D transistor has a positively charged layer between two negatively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The HLB121D 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 HLB121D transistor as follows.
