BC556 thru BC558 Vishay Semiconductors formerly General Semiconductor Small Signal Transistors (PNP) TO-226AA (TO-92) Features 0.142 (3.6) 0.181 (4.6) min. 0.492 (12.5) 0.181 (4.6) • PNP Silicon Epitaxial Planar Transistors for switching and AF amplifier applications. • These transistors are subdivided into three groups A, B, and C according to their current gain. The type BC556 is available in groups A and B, however, the types BC557 and BC558 can be supplied in all three groups. As complementary types, the NPN transistors BC546...BC548 are recommended. • On special request, these transistors are also manufactured in the pin configuration TO-18. max. ∅ 0.022 (0.55) Mechanical Data 0.098 (2.5) Dimensions in inches and (millimeters) Bottom View 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 Maximum Ratings & Thermal Characteristics Parameter Ratings at 25°C ambient temperature unless otherwise specified.
