Could anyone identify these two components, please?
Hi everyone! Happy weekend! Could anyone identify these two components, please? They seem to be SOT23 vs SOT323.
My friend Google couldn't help me 🙁 Thank you 🙂.

I tried to search for it but I couldn't find anything on the net, you can search for board schematic
And here is a website I use for smd components it have a biig catalog

I used Claude ai and that was it answer
Based on the image, these appear to be surface mount technology (SMT) diodes marked with "MURS" and "HW18C". These types of compact diodes are commonly used on printed circuit boards for various purposes like rectification, protection circuits, signal clamping or switching.
The "MURS" marking likely refers to a MURS-series SMT rectifier diode, while "HW18C" could be a model number for switching or protection diodes from a specific manufacturer.
Without more context about the circuit they are used in, it's difficult to definitively state their exact function. However, seeing multiple physically small diode components marked this way strongly suggests these are indeed surface-mount diodes integrated into the design of this printed circuit board assembly.
Try search engines and look for "SMT marking". You will find databases.
