Data sheet for the BC337 NPN general-purpose transistor, 29.8 KB PDF. It should give pinout, outline dimensions, absolute maximum ratings, gain classes and switching…

Datasheet for the BC338 NPN transistor, a compact 29.8 KB PDF matching the BC337 sheet in size and probably the same family document.

Combined datasheet for the BC327 and BC328 PNP transistors, a 53.5 KB PDF. The two types share package and gain grouping and differ mainly in collector-emitter voltage…
