2S Series Transistors
This is where you will find all the transistors specifically in the 2S series: 2Sxxx, 2SAxxx 2SBxxx 2SCxxx 2SDxxxx ..... 2SKxxx
Or if you know the transistor you need then simply type the first 4 or digits in the above search box.
These are also duplicated in the Bipolar transistors listings which is simply one big list covering all transistors.
Please note... transistors in the 2S series from Japan manufacturers very often do not have the "2S" prefix marked, so they will simply be marked Cxxx Dxxx Kxxx.
The example photo on the left shows a 2SC3180 by Toshiba.
