02-19-2021, 06:17 PM

Hello
i need to help with identify this sot-23 part.
It is on lenovo laptop mainboard LV315KB - no schematics
Qxxx marking on mobo - i mean that it will be transistor

It might be a AIC1747-15GJ3, SC70-3 package 1.5v output

Relay Satronic MMI 810.1 bad diode & Transistor

by InsertCoin

Hello and happy new year ,

my Analog Combustion Machine Honeywell gone bad and I don't know what type of diode is utilized.

There is no mark around the body of the diode. The Schematics are general referred only, without any electronics components and values.

The two contacts (2),(5) of the Relay Coil need 48 Volts DC to begin operating. Between these two contacts in series is the bad diode and near of contact (5) is the bad pnp (bc856b) Transistor that can be easily replaced.

I have made a diagram of the PCB and some measurements along some...

help to identify transistor msi ms-15ck1

by elsomer

hi people, i need some help to identify a transistor(q14) that is missing on the board, so the gpu has no voltage i think that q14 activate the phases for gpu, but i dont have schematic or boardview, but i think its the same transistor than q15 and q16, thanks...

Corsair RM1000e - Help identify 5VSB Zener diode

by hobostove

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...

AUO M270QAN01 - identify diode?

by jjne

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...

Identify replacement diode

by jezzaaaa

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...
