FEATURES ♦ NPN Silicon Epitaxial Planar Transistors
for switching and amplifier applications. Especially suitable for AF-driver stages and low power output stages.
♦ These types are also available subdivided into three groups -16, -25, and -40, according to their DC current gain. As complementary types, the PNP transistors BC327 and BC328 are recommended.
max. ∅ .022 (0.55) .098 (2.5) C B E
♦ On special request, these transistors are also
manufactured in the pin configuration TO-18.
