It dissipates power around 115 W when the case temperature is set to 25 degrees.The value of alpha lies between 0.95 to 0.99, however, in most of the cases it is considered as 1.Ībsolute maximum rating of 2n3055 are given below.At positive base to collector voltage, the ratio between collector current to the emitter current is called current gain of the transistor and is denoted by alpha a.Beta value ranges between 20 to 1000, however, its standard value is 200. Beta value is used for the amplification purpose. ![]() Beta has no units as it is a ratio between two currents. It is also called beta current and is denoted by ß.
