I have been looking for the answer to that myself, didn’t find one.
BC / BC SMD NPN transistor
Must be some manufacturer specific numbering system. Some people would tell you that S stands for Silicon but that’s seems to be just an assumption. Thursday, June 7, Why is the transistor BC so-named?
BC is a general purpose NPN Transistor datasheet here which us very popular among hobbyist and engineers alike. But why is it so named? BC is a name registered under the Pro-Electron numbering system. The Pro Electron system is the European type designation and registration system for active components, such st23 electronic tubes and cathode ray tubes, semiconductors, liquid crystal displays, sensor devices, etc.
The system provides integrity of the designations, and creates transparent and unique product identification, thus preventing confusion in the market place.
All Pro Electron type numbers spt23 of a prefix followed by a serial number.
The prefix, generally two or three letters, clearly classifies the devices into categories with a sub-classification into classes, series or families. A few examples of devices registered under the Pro Electron system are: Some of the Integrated Circuits registered under this numbering system are: Lower breakdown voltage versions ending in 8: BC is a lower voltage version of BC Higher breakdown voltage versions ending in 6: BC is a higher voltage version of BC If you are an undergraduate engineering student studying in India and looking to build a project using any of these components, you can procure them from any of the electronic components retail shops that are there in Lamington Road, Mumbai.
BC847 / 547 SMD
One of these is: Checkout this PDF mirrors: Sot233 official booklet describing the complete Pro Electron System 15th edition can be obtained from: Wikipedia article for Pro Electron is here.
About the other two numbering systems: The first digit is one less than the total count of useful electrical bv547. Hence transistors 3 useful connections: The serial number consists of two or more digits assigned consecutively, starting with number 21 for each class of device 1N and 2N are two different classes of devices.
If present, a suffix could indicate various things. For example, a 2NA is an enhanced version of a 2N It has higher gain, frequency, and voltage ratings.
Please check the device datasheet for its significance. Instead of 2N and so forth, some manufacturers use their own system of designations.
Some common prefixes are: Motorola sto23, metal case. Motorola power, plastic case. Motorola low power, plastic case. Texas Instruments TI power transistor, plastic case.
Electronics FAQ: Why is the transistor BC so-named?
TI planar power transistor. TI small signal transistor plastic case. Some popular parts registered under this system are 2SA, 2SB both are transistors. The part numbers under this system consist of a number followed by two alphabets and then a serial number. The system is summarized in the table below: The following figures denote the device serial number. Since this is a serial number may provide insight into date.
A suffix after the serial number indicates that the type is approved for use by various Japanese organisations. Posted by Anurag Chugh at What is SK stands for in Sk January 24, at 5: January 24, at 5: Newer Post Older Post Home.
