Affix “-S-” means the standard TO126 Package.(see package dimensions). If the affix is ”-STS-” instead of “-S-”, that mean the short-lead TO126 package. 2. Suffix “-TU” means the tube packing, The Suffix “TU” could be replaced to other suffix character as packing method. © 2008 Fairchild Semiconductor Corporation 2SC3503/KSC3503 Rev.
