Identifying a component
I need help to identify this burned Transistor from a Ryobi battery charger.
Please check the photo, this is the best i can get for the ID.
Thanks

Re: Identifying a component
lol - you need more than that.

Re: Identifying a component
probably,
if the fet is bad, you should change the zener diode too.
did you check the 2 mbr5200 diodes for shorts?Comment

Re: Identifying a component
check the resistance between the 2 connections on each diode.
remove them first.Comment

Hi,
As topic sais, i need help identifying a SOT23 NPN transistor.
Marking on the transistor is labeled 6CE, will try uploding a picture. -

Hey. I have a Fujitsu U757 motherboard with number CP732277. And i want to replace it with U758 motherboard like with CP755900 or whatever U758 series motherboard. U747/U757(7th gen CPU) all motherboards look exactly same so i'm sure it won't matter which one to use. But i would like to upgrade a bit and get U748/U758(8th gen CPU) motherboard. Motherboards all look exactly same layout as U747/U757, but i found one chip is soldered on U747/U757 which U748/U758 doesn't have. It is STM32F103 MCU which is near screen connector. And i'm not sure will U748/U758 motherboard will work with my U757 laptop....01-28-2024, 05:01 PM -
Hello
Got this speaker from a friend , defective. Power led comes on and off , in a loop.
Disassembled, got the board out, and after a bit of measuring I found a low resistance on a 5v6 line. With a bit of current I found a transistor heating up on that line (labeled T1 and 113 as on pic).
After removing this guy, I got a value of 0.7 in diode mode on that 5v6 line, which before had 0.02 or something like that.
I tested powering it up without the IC, and the speaker turns on and stays on, and works fine
Still, I need to replace this transistor.... -
I picked up this used Bose Acoustimass 10 IV speaker system. Speakers seem to work fine, but the subwoofer does not make any noise. So I took apart the unit and found some obviously failed (burnt) components:
- 1x 3.14 A @ 250V main circuit fuse
- 1x bridge rectifier GBU601. there's actually two of these on the board, one is obviously burnt and the other does not seem to have any anomalies like shorts. However I figure may as well replace both.
- 2x diode. This is tricky because the only markings I see on it are: "617 402". No current rating or anything else....
