BC558 Transistor TO92 PNP Transistor CDIL BC558

Product Overview:

A through-hole PNP silicon epitaxial planar small-signal bipolar junction transistor housed in a standard TO-92 plastic package. Designed for low-noise, low-voltage, and low-current general-purpose amplification and switching applications, it is a staple component in signal-processing circuits, preamplifier stages, and logic switching circuits. It frequently serves as the complementary PNP pair to the BC548 NPN transistor.
