can't figure out this strange symbol
can see its a 1.5ke series but its the next bit . 1?ca .. is it an 8 i wonder ?

Re: what is this symbol on tvs diode ?
likely 1.5KE18CA -
Re: what is this symbol on tvs diode ?
Just this one is bi-directional, since the band on on side of the diode is missing.Comment

Re: what is this symbol on tvs diode ?
I didn't look at the datasheet, as I just looked at your pics and noticed no bands and nothing was mentioned. Carry on! :-DComment

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.... -
Hello everyone, I'm repairing an LG TV backlight and I noticed some strange behavior when I touching the backlight strip with a missing Zener diode.
So I replaced the leds on the strips and they seemingly working fine, but soon as I touch the strip which has a missing Zener diode the whole backlight turns off for a few seconds and then turns back on.
Is this caused by the missing diode? If so what kind of zener diode should I use to replace it?.
The led strips has 9 6V leds.

Hello everybody☺️ I am glad to be here and looking forward to a good discussion.
First of all, I am new here. Therefore I will shortly introduce myself.
I am Nico and currently I study Physics.
In my freetime I like to build and repair stuff. Especially big battery's.
A few years ago I got myself an electric unicycle, monowheel or however you call that.
The battery bms was broken so I replaced and resolder that. Nothing big.
I used this thing for some years and had a lot of fun. Unfortunately I used it last time in heavy rain. Usually everything... -
Hello Everyone,
I have 1 diode on a circuit that I suspected to be faulty because the forward and reverse bias has a voltage drop reading.
While compared to the reading of another diode from the next channel it won't read at reverse bias.
Now the problem is; it does not have any body marking.
So I tried to sketch the diagram and found out that it is connected to the base and collector of the C3632 transistor.
What do you think is this diode?
Can you please suggest what part number can i use to replace this faulty diode instead?
Hoping that you... -
I was looking at an old battery powered electric lawnmower I picked up as the previous owner didn't want to buy a new board to replace a ruined old board. Tried to study how it was designed - it appears it has a huge 80A contactor...or rather, a 80A relay. It appears to be SPDT to control the motor. A 30A relay protects the circuitry.
The weird thing I don't quite get is how this thing is connected. The common contact is connected to the motor. The NO contact is connected to the battery, which is expected, so when the relay is activated, the common is connected to the NO contact and...
