So far i put there instead of ME 71 another diode with similar package size (again, i'm not sure which one! It has one blue line on anode side, but no letters or numbers). The device works :-) Those SMD elements seems to be very difficult to identify :-( I can't find this ME 71 on Vishay site.

Yes, Hero999, you right, i don't know for sure that this is the inly broken element. But this is my best bet so far, at least change this element, which is obviously broken :-) Problem is i don't have any idea about current rating of this element, will have to make some research about highest available. Are there some general rules about SMD diodes marking?

Here is better image of the same element ( i got another camera which makes better macro), please if somebody can recognize the manufacturer of the D15 diode by logo , let me know which company is it!

Looks like General semiconductor logo to me. But no ME 71 on their site.

Hi, i have a problem with one element on PCB of the base of iRobot Roomba 560 (picture of the part of the scheme is here , specifically D15, D16, marked as ME 71. Can anybody tell which company is a manufacturer of it, and what is it (diode may be)? Also , if anybody knows where to get the spec for this element (or similar 812 ME, it was on the same position but in another device), i would appreciate it very much! Thanks! http://static.electro-tech-online.com/imgcache/1772-irobot%20roomba%20base%20scheme%20-%20ME%2071%20element.jpg
