Took a picture of a diode taken from a Philips Monitor 24" PCB
Looking to identify it please.

Hey there guys. I've got a Corsair power supply that's come across my bench dead. I usually don't mess with power supplies, but it's a slow week so I'm giving it a whirl.
Taking it apart I heard a screw rattling around inside, and when I got it apart I found a couple blown components near what I think is the 5VSB area.
There's a 22ohm resistor that's melted and open, but it still has the bands.
The other part is a zener diode and it's top went to jesus, so I can't read the marking.
It looks like the diode connects the source and drain of a TNY284... -
Hi,
I have a small number of monitors based on the above panel and am working through them. I have at least two with a single, burned-out diode. From what I can see it's something like DI428 or DII428 or DH428. Here's a picture of a working one.
Can anyone identify this please? Based on the number 428 it may be a shottky or a Zener according to Google. The device in question is D105.
ETA I can confirm that the number is definitely 428 (I took a video which revealed a better image), the DII appears to be a maker's mark. There's also a code 1G. Looking around... -
I'm trying to find a replacement diode for one that has gone short.
I have a generic USB charger that went short circuit to ground on 5V. I found that one of a pair of identical diodes in parallel (and in series with transformer secondary winding) has gone short in both directions, so I suspect it's bad. The marking is CSRS1045, which I believe is a low barrier Schottky with max current 10A and max reverse 45V. I found a spec sheet for CSRS1045-A that has same specs and also says 350mV drop when forward biased.
I can't find the exact part number for sale. Similar... -
Hi again guys.
Ive got a Ubiquiti 24 port POE Switch which has failed to work. Fans turn on, but no lights.
I've ripped the board out, flipped it upside down and noticed a blown 3pin SMD Diode (at location D53). Marking is ESSP (as with all the other Diodes in the same row).
Anyone help me identify the model of this Diode ?... -
Heyo
I'm trying to perform data rescue on this drive and don't want to make a mistake. I've found a burned diode and a shorted capacitor right next to it. I've found a component on eBay that seems to match up. Can someone confirm please? Also I don't mind replacing it with a compatible component if it's easy to get hold of.
