Pin Configuration (TO-92 Package):

Emitter (E) – Connected to ground (for typical common-emitter circuits)
Base (B) – Controls the transistor (small current at the base controls larger collector current)
Collector (C) – Connected to the load in a switching or amplification circuit

Applications:

Signal amplification
Low-power switching circuits
Oscillators and signal processing
LED drivers
Logic circuits
