Hi,
I have put an arrow to where the diode is, it is connected to the coil of the relay where i draw a box. At the bottom of the box is the normally open contact for the relay. The IC is lm393. This a power supply but i noticed when I plug in, the relay is not being powered on, thats why i am now focusing around this area.
1) The relay coil is driven by Q22 so is Q22 good and is it being driven to turn on to supply the current to the relay coil?
2) What Voltage testing have to done so far?
What Voltage do you have on each leg of the relay coil with ref to GND?
3) Where are the pictures of the whole top and bottom side of the board?
Thanks budm, I traced the voltage from q22 and it leads to a voltage regulator that is undervoltage, suppose to be 14vdc(relay coil voltage rating is 15v) and i measure 4volts.replaced the regulator and it did start up the power supply.
But I still dont know what/how to replace this diode. fortunately it wasnt defective and there was no need to replace it
The designation is D10 is there any other diode have ZDxx? If yes than it’s probably just a generic 1N4148. De solder it and check with a multimeter diode test, if bad than try to install new 1N4148.
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...
It is very hard to find this MPG06J diode in my place.
I think that replacement should have the same ratings with MPG06J, But it is impossible for me to hunt down replacement for MPG06J diode.
Any reply would be appreciated.
Hi there, looking for a compatible replacement for a diode type labelled "V6 18" from a dead Panasonic plasma TV power source. Possibly a V6 600 volts diode as seen here: https://electronics.stackexchange.co...nt-diode-v6-88 ?
Thank you ...
Hello, I am looking for help to replace a damaged diode. The tristar was replaced and a diode was damaged in the process. I have a picture of the diode but dont have an exact donor. I mostly have macbooks for donors and only a few ipad and iphone boards. Diode part number: DSF01S30SCAP
Im not sure where to find the ipad board number. Anybody have an idea where else this diode is used on other boards? Thanks....
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...
