The first two or three digits indicate the family type, in compliance with the naming rules of the Japan Electronics and Information Technology Industries Association (JEITA).
2nd digit: S stands for semiconductor.
3rd digit: Indicates the function
|2SA||Bipolar-type transistor||PNP, for high frequency|
|2SB||PNP, for low frequency|
|2SC||NPN, for high frequency|
|2SD||NPN, for low frequency|
|2SJ||Field-effect-type transistor (FET)||P-channel|
|3SJ||P-channel (2 gates)|
|3SK||N-channel (2 gates)|
Remarks 1.Product names starting with 1N or 2N follow the American naming format.
Remarks 2.Product names starting with the following codes are original to Renesas Electronics.
N:New-model general-purpose transistor or FET named using a different system to the JEITA naming rules
|Family type||Withstand voltage rank||Rank-based serial number||Type||Revision||Special standard||Detailed package classification||Taping||Lead (Pb)-free|
The Withstand voltage rank and Type categories are described below. See the 2SJ600 example further down for details of the categories following Revision.
Withstand voltage rank
NP:Power MOS FET for automotive electrical applications
|Family type||Product number||Package code||Taping||Lead (Pb)-free|
NDL, NR, NX:Optical diode for communication (NDL: obsolete)
NV:Visible laser diode (obsolete)
|Product number||Revision||Special standard||Detailed package |
|Family type||As described above.|
|Product number||The product number is described using numerals.|
|Revision||The chip revision number is expressed as a single letter (the revision number increases in alphabetical order). |
First releases (products that haven't been revised) have no revision indication.
|Special standard||Describes the special features of the product, including its quality grade and lead formation.|
|Detailed package classification||-Z indicates products that have been changed from through-hole packages to surface-mount packages using standard pin formation processing.|
|Taping||For products shipped on a tape reel, codes such as -E1 and -E2 are added to show the direction of the product on the tape. |
One exception is the non-reel version of the SC-59 package, which has the code -L added.
|Lead (Pb)-free||Classification codes such as -A and -AZ are suffixed to the Orderable Part Number of lead-free products.|
Remarks 1.Some products may have characters such as /JM suffixed to their Orderable Part Number. These characters indicate where the product was manufactured. The first character after the slash indicates the country where the manufacturer of the IC diffusion processing is located, and the second character indicates the country where the product was assembled.
In the case of /JM, the J stands for Japan, and the M for Malaysia. If two products have the same Orderable Part Number except for these characters, the functions, performance (i.e., electrical specifications described in the data sheet) and package of the products are the same, regardless of where the product was manufactured.
Remarks 2.The rank classification of Zener diodes (B1, B2, etc.) and the hFE rank of transistors do not form part of the Orderable Part Number. These are handled separately.
