BC546 thru BC548 Small Signal Transistors (NPN) TO-226AA (TO-92) Features * NPN Silicon Epitaxial Planar Transistors * These transistors are subdivided into three groups A, B, and C according to their current gain. The type BC546 is available in groups A and B, however, the types BC547 and BC548 can be supplied in all three groups. As complementary types the PNP transistors BC556...BC558 are recommended. * On special request, these transistors are also manufactured in the pin configuration TO-18. 0.142 (3.6) min. 0.492 (12.5) 0.181 (4.6) 0.181 (4.6) Mechanical Data max. 0.022 (0.55) 0.098 (2.5) Dimensions in inches and (millimeters) Case: TO-92 Plastic Package Weight: approx. 0.18g Packaging Codes/Options: E6/Bulk - 5K per container, 20K/box E7/4K per Ammo mag., 20K/box Bottom View Maximum Ratings & Thermal Characteristics Parameter Ratings at 25C ambient temperature unless otherwise specified.
