jemima Posted June 12, 2006 Report Share Posted June 12, 2006 I have a couple of AD149 transistors, and I would like to use them for something. Can anyone help me with a datasheet please...jemima Quote Link to comment Share on other sites More sharing options...
ante Posted June 12, 2006 Report Share Posted June 12, 2006 Hi jemina,Welcome to our forum.The AD149 is really old, save it as an antique. ;)I built my first bench PSU using an AD149 about 35 years ago! ;DHere are some data for the AD149:Description = Ge PNP Power BJTV(BR)CEO (V) = 30V(BR)CBO (V) = 50I© Abs.(A) Collector Current = 3.5Absolute Max. Power Diss. (W) = 22I(CBO) Max. (A) = 350uh(FE) Min. Static Current Gain = 30h(FE) Max. Current gain. = 100@I© (A) (Test Condition) = 1.0@V(CE) (V) (Test Condition) = 1.0f(T) Min. (Hz) Transition Freq = 300kPackage = TO-3 Quote Link to comment Share on other sites More sharing options...
