Semiconductor Components Industries, LLC, 2013 September, 2013 2SA2040/2SC5707 Bipolar Transistor (-)50V, (-)8A, Low VCE(sat), (PNP)NPN Single TP/TP-FA Applications • DC / DC converter, relay drivers, lamp drivers, motor drivers, ﬂ ash Features • Adoption of FBET and MBIT processes • Large current capacitance The BC107 transistor costed Rs. 15. Yesterday I bought a 2N3904 transistor that costed only Rs. 6 and it gave me almost the same result as the first transistor. Now my question is, what is the difference between the two, that their cost varies this much. Also what would be the different applications of the two transistors?
