bc337 338 1.pdf datasheet:

BC337 and BC338Vishay Semiconductorsformerly General SemiconductorSmall Signal Transistors (NPN)TO-226AA (TO-92)Features NPN Silicon Epitaxial Planar Transistors for switching0.142 (3.6)0.181 (4.6)and amplifier applications. Especially suited for AF-driverstages and low power output stages. These types are also available subdivided into threegroups -16, -25, and -40, according to their DC currentgain. As complementary types, the PNP transistorsBC327 and BC328 are recommended. On special request, this transistor is also manufacturedin the pin configuration TO-18.Mechanical DataCase: TO-92 Plastic Packagemax.
