BC337 Transistor TO92 NPN Transistor 800 mA 45V LGE BC337-40

Product Overview:

A through-hole NPN silicon epitaxial planar small-signal bipolar junction transistor housed in a standard TO-92 plastic package. Designed for medium-current, low-voltage amplification and high-speed switching applications, it provides excellent current gain linearity and low saturation voltage. It is frequently employed in driving small relays, LEDs, audio driver stages, and general-purpose logic switching circuits. It serves as the direct complementary NPN pair to the PNP BC327 transistor.
