How can I determine the junction area of a diode?

AI Thread Summary
To determine the junction area of a diode, it's essential to identify the type of diode, such as small signal or power, as well as its construction. For small diodes, manufacturers like Philips often provide die information that can be helpful. If this information is unavailable, decapsulating the diode and examining it under a microscope may be necessary, though this process is challenging. Understanding these methods is crucial for accurately assessing the junction area. Proper identification and potential disassembly are key steps in this determination process.

Hi Guys!

How are u my friends?

Well i want to ask u one important thing!

Please tell me the way to find out the junction area of a diode

Thanks in advance

You have to know what type of diode you are dealing with i.e small signal , power
and so on , also the type of construction . Some diodes (small ) are made from chips
and the die information may be available from the manufacturer, Philips is pretty good for that . Otherwise it maybe required to literally decapsulate the device and look at
it under a microscope ( not impossible but difficult ) . Ray

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
