Type identification using transistor name

[demetal]

Hi,

what all things can be identified from a transister number (or name)...

 

[KJ6EAD]

Manufacturer, part number and lot number. By looking up the manufacturer's datasheet for the part all electrical attributes can be determined. There are several numbering standards such as JIS, Pro Electron and JEDEC: Transistor - Wikipedia, the free encyclopedia.

Do you mean the letters in general like this

From the transistor no. eg BC547, you can find out everything required about the transistor by referring to its datasheet. You can find the maximum voltage that can be applied, its gain, if it is NPN or PNP, the Vce(sat), storage time, pin layout, current capacity, maximum power dissipation, etc.

Search for the datasheet on Google or use Datasheet catalog for integrated circuits, diodes, triacs, and other semiconductors, view

Hope this helps.
Tahmid.

thanks alex... This was what i was talking about... Is it applicable for all devies..?

I think so but as the link says there are also manufacturers that introduce their own types.
