2N4923 NPN General Purpose Transistor
1,00 EGP
Description
The 2N4923 is a robust NPN power transistor designed for medium-current, medium-voltage switching and amplification applications. With a collector current rating of up to 2A and a collector-emitter voltage of 80V, this transistor is ideal for motor drivers, relay controls, power regulation circuits, and other general-purpose electronics requiring higher current handling.
Housed in a TO-225 (also known as TO-126) package, the 2N4923 is suitable for heat-sensitive designs, thanks to its enhanced power dissipation capability when properly heatsinked.
