BJTswhich
BJTswhich is not a recognized term in electronics literature. It may be a misspelling, concatenation, or a coined label for topics around BJTs and switching. This article clarifies what BJTs are and how they are used as switches, which remains a common interpretation in practical circuits.
Bipolar junction transistors are current-controlled devices with three terminals: emitter, base, and collector. They come in
When used as switches, BJTs are typically configured in a common-emitter arrangement. In an NPN switch, a
Device selection considers maximum collector current, collector-emitter voltage, switching speed, and power dissipation. Common criteria include
