2SD667 npn Transistor TO92L JSMSEMI 2SD667A

Product Overview:

A through-hole NPN silicon epitaxial planar bipolar junction transistor housed in a TO-92L (long body) plastic package. Engineered for low-frequency power amplification and vertical deflection output stages in television receivers, it offers excellent linearity and high voltage handling within a compact footprint. Its extended TO-92L body provides superior thermal dissipation compared to a standard TO-92 package. It frequently serves as the complementary NPN pair to the 2SB647 (or 2SB647A) PNP transistor.

Core Specifications:
