I need help identifying an smd diode (see picture) It appears to have 5423 written on it, but I can't find anywhere a diode by this code. I did however find an smd diode by googling 5243 (I figured that it I might have to read it vertically, not horizontally). Also, 1 of these reads 0.1 when tested with multimeter and another reads 0.2. I have desoldered them both to be 100% sure and the result remained the same. Does that mean the one with 0.1 voltage drop is the bad one? I also tried switching multimeter leads, both read OL as expected. Also, I measured resistance: the one with 0.1 voltage drop read 200-300 ohms, whereas the other one was OL (that's while probing using the correct polarity). After switching multimeter leads it read OL resistance for both diodes. Thank you in advance!
