Where can I find the SOT23 marking code?
Normally the part number is represented by a marking code printed on top of the SOT23 package. The follows presents some of the SOT23 components marking code, which is useful for reverse engineering use. Warning Note: Please ensure the context of the component used in the electronic design is correct.
What’s the pitch of the SOT-23 component package?
A 3D render of the SOT-23-6 (SOT-457) component package. The 3, 5, and 6 pin SOT-23 variants have the same pitch of 0.95mm, and all are compatible with the 6 pin footprint (which means you can use a SOT-23-6 adapter board for the 3 and 5 pin variants also).
What was the first version of SOT-23?
Variations exist with 3 to 8 pins. When surface mount components were just beginning to gain popularity, SOT-23 was introduced to replace the well used through-hole 3-pin TO-18 and TO-92 transistor packages, and so the first variant of SOT-23 was the 3 leaded version (SOT-23-3, officially called TO-236AA by JEDEC).
Is the SOT-23 3 and 5 pin compatible?
The 3, 5, and 6 pin SOT-23 variants have the same pitch of 0.95mm, and all are compatible with the 6 pin footprint (which means you can use a SOT-23-6 adapter board for the 3 and 5 pin variants also).
What are the markings on a SOT-23 transistor?
I’ve got a SOT-23 transistor (I think, but it could also be an IC) marked with 1E. Another one is marked with A7W. Then I can also see WR5.
Is the part number printed on the chip?
The SOT package is small and normally the full part number cannot be printed on the chip itself. Normally the part number is represented by a marking code printed on top of the SOT23 package. The follows presents some of the SOT23 components marking code, which is useful for reverse engineering use.
Where to find the SMD marking code on a component?
Read our terms of use and legal disclaimer for more details. Fill in the marking code found on the top surface of the SMD component, then fill in the human verification number, which ensures only real people use the data and click the “Search” button. Searching is case-sensitive.
