The 20 pages that link to Bipolar junction transistor, each with the reason it gives.
P–n junctionRelated: Its operation depends on carrier injection across an emitter–base junction.
MOSFETCompared with: Unlike a MOSFET, it uses minority-carrier injection and requires base current.
Junction transistorBroader topic: It is the most common modern meaning of junction transistor.
NOR gateRelated: Bipolar transistors can implement NOR gates in logic families such as TTL.
