![]() To transistor at a low price and good quality, please visit 1N4148. The author was the global business manager of the Discrete division of National Semiconductor in Silicon Valley in the late ’80s. Understanding the transistor nomenclature system will help you find the SMD version of a transistor much easier and much accurate. You have to compare the specifications in detail. Some cross-reference suggests that the SMD versions of the 2SC1815 are available as the 2SC2712 (SOT-23), 2SC4738 (SOT-23), KTC3875 (SOT-23) and KTC3875S (SOT-23). The maximum current gain of this transistor is around 800. BC547 is usually used for amplification and switching purposes. The current flowing from base to the emitter controls the current flowing through the collector. Pro Electron is less user friendly, SMD equivalent of BC547 is not simply MMBT547.Ī) There are some part numbers follow a system that BC8xx is an SMD version of BC5xx.ī) Some part numbers follow a system BC8_x is a SMD version of BC5_x. BC547 has three terminals as in other transistors. JEDEC is relatively user-friendly, SMD equivalent of 2N3904 is simply MMBT3904, 2N3906 is MMBT3906, and so on. JEDEC is a North American standard developed in the United States that is also worldwide.IS is an acronym for Japanese Industrial Standard, and it is used in Japan,.BC546/7/8/9 SMD Equivalent is BC846/7/8/9 The transistor part number nomenclature are JIS, Pro Electron, and JEDEC. ![]()
