I have to replace 2 of these on a board. The size is 4.3mm x 3.5mm and has LT88A on it. I don’t know what the symbol means but there is another component with the same symbol, SM8S36A. I tried to use that to find the manufacturer but I just find stuff from China.
The symbol looks like a Vishay marking, and there is an example on page 04 of this document: [click here https://www.vishay.com/docs/88912/diodesgroupbodymarking.pdf ]. The part number that you referenced also suggests Vishay.
For Vishay, there is often a “type” code in the marking, and that might be “LT” as shown in this document on page 02: [click here https://www.vishay.com/docs/89421/smbg.pdf ].
Using part number SMBG18A from that line, and Vishay as the manufacturer, I found these results on our site: [click here https://www.digikey.com/short/zd97v4 ]. I wasn’t yet able to identify the last specs, but this should be close.
Bill has it right. From his link, this is the one we have in stock:
Awesome, thanks guys I really appreciate it.
