[QUOTE="Cats, post: 739953"] I want to use an STM32F103 Microcontroller and power it with USB + get some data from the Microcontroller via the USB D+/D- lines. Now this is the refference design I came up with, using the AN4879 and AN5612 application note from ST. [URL='https://i.sstatic.net/0kkqUnMC.png'][IMG alt="enter image description here"]https://i.sstatic.net/0kkqUnMC.png[/IMG][/URL] As this is my first Project of using an USB Port on an PCB, I just want to verify that this is a valid protection for the Microcontroller pins. I also want to exchange the ESDA7P60-1U1M, that is recommended for the circuit by ST, because I want to order it from JLCPCB and would prefer to stick to the basic components. But this diode seems a bit special because I have not found one with the same characteristica. Could you also give me some impression what are the important parameters of this diode? [/QUOTE]
