BC846 THRU BC849 Small Signal Transistors (NPN) FEATURES ♦ NPN Silicon Epitaxial Planar Transistors SOT-23 .122 (3.1) .118 (3.0) .016 (0.4) .056 (1.43) .052 (1.33) ♦ Especially suited for automatic insertion in thick- and thin-film circuits. ♦ These transistors are subdivided into three groups A, B and C according to their current gain. The type BC846 is available in groups A and B, however, the types BC847 and BC848 can be supplied in all three groups. The BC849 is a low noise type available in groups B and C. As complementary types, the PNP transistors BC856...BC859 are recommended. .016 (0.4) .045 (1.15) .037 (0.95) .037(0.95) .037(0.95) .007 (0.175) .005 (0.125) 2 max. .004 (0.1) 1 for switching and AF amplifier applications.
