CNL639 Transistor TO92 CDIL NPN Transistor 80V 1A CDIL CNL639

Product Overview:

A through-hole NPN silicon planar epitaxial bipolar junction transistor housed in a standard TO-92 plastic package. Designed for general-purpose switching and medium-power linear applications, it provides reliable switching and DC amplification performance. It is frequently utilized in industrial control circuits, DC amplifiers, relay drivers, microphone preamplifiers, and lighting systems. It serves as the complementary NPN pair to the CPL640 PNP transistor.
