C1815 Transistor CDIL NPN Transistor TO-92 50V 150mA C-TCSC1815G 1815 CDIL C1815

Product Overview:

A through-hole NPN silicon epitaxial planar small-signal bipolar junction transistor housed in a standard TO-92 plastic package. Engineered for high-gain general-purpose amplification and high-speed switching applications, it features excellent $h_{FE}$ linearity and an exceptionally low noise figure. It is a staple component in audio frequency preamplifiers, signal processing circuits, and low-power driver stages. It serves as the complementary NPN pair to the A1015 PNP transistor.
