DC COMPONENTS M7 | Diode: rectifying; SMD; 1kV; 1A; us; Package: reel, tape; DOAC – This product is available in Transfer Multisort Elektronik. I had a look at the schematic- the purpose of that diode on the input is to short out a reverse-polarity input. Diodes are pretty rugged and tend to.

arduino – What is is an “M7” Diode – Electrical Engineering Stack Exchange
But I mean specifically what does the M7 mean. I certainly can’t just go to digikey and order an M7 diode because such a part does not exist.
,7 making a 7m arduino clone using kicad for my own use and intend to put a fuse or possibly resettable fuse in front of that diode so as it doesn’t burn out etc See here for the circuit see the external power supply circuit: They definitely exist I have a reel of a similar type kicking around somewhere and they are very popular in Asia typically from suppliers that are lesser known in the West.
I had a look at the schematic- the purpose of that diode on the input is to short out a reverse-polarity input. Diodes are pretty rugged and tend to fail short, so unless the source is something like a car battery or PC power supply, there’s a good chance it won’t fry the board.
Diode Rectifier M7 (SMD 4001-4007)
Home Questions Tags Users Unanswered. It appears to indicate that the diode must have a v reverse voltage.
Spehro Pefhany k 4 I have always thought such riodo were used as user-input voltage protection, but with a PIV of V it must be that these are rather for ESD protection. EMFields Yup, and across relay coils. There is little if any price premium for higher voltage though, like their 1Nx cousins.
SMD Rectifier M1-M7 ( SMD ) – Suntan
As I said in my edit, that one is shunt reverse polarity protection. There’s no reason to have it rated more than 50V PIV. I was writing to sherrellbc and forgot to address the comment; sorry diofo that. Note that they are relatively slow, with several microseconds reverse recovery time.
