Hello, I have multiple faulty SMD Diodes with this top marking. They are in a NovaElectric UPS. I appreciate any assistance identifying this component.
Hello chuhn,
Welcome to the DigiKey TechForum.
Do you have any other information on this, to help us identify it?
Any idea on the voltage that goes to it, or the physical size of t he body?
What is the size of the solder pads it attaches to, and the space between them?
The physical size of the body is 0.11" (2.8mm) long X 0.063" (1.6mm) wide. The greatest dimensions of the pads is 0.28" (711mm) long X .11" (2.8mm) wide. The reference designation on the CCA is D45. Thank you for the response.
could it be this one?
MMSZ5226BT1G, Zener Diodes, 3.3V, 500mW/0.5W, SOD123/1206
If you llok at the data sheet on this link: https://www.digikey.com/en/products/detail/onsemi/MMSZ5226BT1G/919744?s=N4IgTCBcDaILJwMoC0CsYwDYBCAVAjAOIgC6AvkA
The marking is the D1 and the dimensions look the same. It very well could be this part.
