Is anyone familiar with marking on surface mount diode?
I have two:
J3H
F4J
They both are about 2.67 mm x 1.62mm.
Thanks

TE Circuit Protection offers the widest selection of surface-mount fuses available for addressing a broad range of overcurrent protection applications. Helping to prevent costly damage and promote a safe environment for electronic and electrical equipment, our single-use chip fuses provide performance stability to support applications with current ratings from .5A up to 20A.
TE Circuit Protection also offers the telecom FT600 fuse for telecommunications applications. This telecom fuse helps comply with North American overcurrent protection requirements, including Telcordia, GR-1089,...10-07-2024, 06:07 AM -
Hi all.
I started a thread while back regarding TV power supply standby circuitry as it is something I am not quite on top of.
SMPS theory and function is becoming more familiar, however the standby part is still a bit of a mystery.
Anyway, a friend has this TV with the above mentioned power supply board which has no standby voltage, nor any other voltages leaving the board.
The mains AC comes in fine, gets filtered and rectified with power is on the main filter cap as well as the transformer and drain pins of the ICE3B0665J, but that's it.

I'm trying to identify a small SOT-package IC marked "XA2LD" located near the 5V_FS rail on a logic board. The silkscreen shows it as U26/U25, and it's adjacent to components labeled R415, C232, L28, etc.
Here’s what I know so far:- The IC marking is XA2LD (possibly custom or abbreviated).
- It’s likely involved in power switching or regulation (possibly a load switch or LDO).
- The package appears to be SOT-23-5 or similar.

Hi,
i'm looking for a component from the picture with marking "JWCXJ 2HB1N" it is just after Ethernet IC.... -
I have to replace the surface mount diodes in the attached picture, because they are open, so I need help in identifying them. The marking on the printed circuit board starts with the letters CR, the markings on the diodes are NM 64 A. The dimensions of the diodes are 3.5 x 5.5 millimeters. Which one should I order as replacements?...
