I’m not to familiar with these types of diodes, just wanted a confirmation that it is in fact bad as I am interrupting from the DMM testing, and that I do have the right data sheet for this component so I can buy new ones.
D403/SK 2B: DMM Diode mode shows 0.012-0.13v both ways, from what I’ve read I am supossed to get between 0.2-0.4v one way, all 4 are reading similar.
Also wanted to confirm that I do have the right data sheet, I think I do but I don’t want to just assume.
Half the high&low outputs blew due to abuse and very bad environment conditions. The 4 to the left if looking at board right side up, 4 to right if looking at pic as is, upside down.
Thankyou 🖖🏼

D403 and the other corresponding diodes are in parallel with 3 resistors. You need to remove the diode from the circuit and recheck it.
