2SB14140RA working principle

The 2SB14140RA is a bipolar junction transistor (BJT) device, wherein two p-n junctions are formed between a single N-type transistor material and two P-type semiconductor materials. The base of the transistor is the P-type material, while the collector and the emitter are connected in series with the N-type material. As the emitter-base junction of the transistor becomes forward biased, the resultant current flows through the external circuit to the collector. The 2SB14140RA transistor amplifies the current flowing through the external circuit, enabling larger currents and higher voltages to be driven to the load.

The 2SB14140RA can be characterized as a low-power device, since it can only handle currents up to 100 mA and voltages up to 20 V. It is also a low voltage device, since its operating voltage can range from -35V to +20V. Finally, the 2SB14140RA is a general-purpose device, and it is an ideal choice for low-voltage circuit applications.
