S9014 Transistor Pinout, Datasheet, Applications, and Replacement Equivalent
The S9014 is a versatile and widely used NPN bipolar junction transistor (BJT). Its affordable price, general-purpose functionality, and ease of availability make it a popular choice in electronic circuits. In this blog post, we will explore the S9014 transistor's pinout, datasheet specifications, applications, and suitable replacement equivalents.
Pinout of the S9014 Transistor
The S9014 transistor has three pins:
Collector (C): The collector is the primary output terminal where the main current flows.
Base (B): The base controls the transistor's operation. A small current at the base allows a larger current to flow between the collector and emitter.
Emitter (E): The emitter is the terminal through which the current leaves the transistor.
The typical pin configuration (when looking at the flat side with the legs pointing downward) is as follows:
Pin 1: Emitter
Pin 2: Base
Pin 3: Collector
