Web31 mrt. 2024 · Bipolar Junction Transistor (BJT) is a three-terminal, three-layer, two-junction semiconductor device. Emitter (E), Base (B), and Collector (C) are the three terminals of the device. A BJT is capable of handling two polarities (holes and electrons), it can be used as a switch or as an amplifier and is also known as a current control device. 2.) WebSimply put, a BJT is a three-terminal semiconductor device. The name "bipolar" comes from the fact that this type of transistor contains two types of semiconductor material—one positive type (p-type) and one negative type (n-type)—through which a current flows. Bipolar junction transistors usually contain silicon.
