Wikipedia article for Pro Electron is here. BC is sdm general purpose NPN Transistor datasheet here which us very popular among hobbyist and engineers alike.

BC Transistor NPN 65V A TO BCB,

The part numbers under this system consist of a number followed by two alphabets and then a serial number. Since this is a serial number may provide insight into date.

For example, a 2NA is an enhanced version of a 2N Texas Instruments TI power transistor, plastic case. The system provides integrity of the designations, and creates smmd and unique product identification, thus preventing confusion in the market place.

SMD-BC546 (Per Pack)

Please check the device datasheet for its significance. It has higher gain, frequency, and voltage ratings. Some popular parts registered under this system are 2SA, 2SB both are transistors. A suffix after the serial number indicates that the type is approved for use by various Japanese organisations.


Some people would tell you that S stands for Silicon but that’s seems to be just an assumption. A few examples of devices registered under the Pro Electron system are: If present, a suffix could indicate various things.

Motorola power, metal case. The following figures denote the device serial number. Some of the Integrated Circuits registered under this numbering system are: Newer Post Older Post Home. LARE is one of my ex-workplaces.

What is SK stands for in Sk January 24, at 5: The system is summarized in the table below: Motorola power, plastic case. Higher breakdown voltage versions ending in 6: Must be some manufacturer specific numbering system.

The first digit is one less than the total count of useful electrical connections. I have been looking for the answer to that myself, didn’t find one. If you are s,d 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.

BC is a higher voltage version of BC BC is a name registered under the Pro-Electron numbering system. The prefix, generally msd or three letters, clearly classifies the devices into categories with a sub-classification into classes, series or families.

But why is it so named? The serial number consists of two or more digits assigned consecutively, starting with number 21 for each class of s,d 1N and 2N are two different classes of devices. Posted by Anurag Chugh at Thursday, June 7, Why is the transistor BC so-named? TI planar power transistor. Some common prefixes are: Motorola low power, plastic case.

All Pro Electron type numbers consist of a prefix followed by a serial number. TI small signal transistor plastic case. Lower breakdown voltage versions ending in 8: Instead of 2N and so forth, some manufacturers use their own system of designations. About the other wmd numbering systems: One of these is: The official booklet describing the complete Pro Electron System 15th edition can be obtained from: BC is a lower voltage version of BC
