Problem with identifying elements

[valter_ppk]

Hi all,

Could you please help me with identifying elements marked as: WKX (SOT23 package), V1121 (SOP 4 package) and AL P86. All of them you can find in attached pictures.

Thank a lot for any help.

I think they could be:

an LDO S-1737D33-M5TS1
a photovoltaic mos APV1121
a transistor BCX53-16

please check the following datasheets:

Hello,

You are right with Infineon and Panasonic elements - I've checked them by multimeter, but in case of WKX I have doubts because on my board WKX is in SOT23 package and in the manual in mouser web there is no information that WKX could be in SOT23...

If you have a look at the datasheet I post in#2, you can find the SOT23-5 package. In the part number this is indicated by M5T1 (see page 4), so if you seach at page 34 for the code VKX you'll find the PN S-1137D31-M5T1y. Sorry, in the previous post I copied a wrong PN.

But there's no SOT23-5 in the photo.

You are right, sorry I didn't open the pictures.
