how to test a RF schottky diode with a multimeter

[arezuabdi]

Hello everyone
I was wondering if you answer the following question:
Could I test an RF schottky diode (as an example HSMS282x) with a multimeter like other typical diodes to make sure the diode does not burn and it is ok?
If no, could you please tell me how I do it?
thanks a million

Hi,

with a multimeter yo can´t measure HF features.
But you can test the DC specifications.

Like forward voltage drop:
Use a 10V supply (doesn´t need to be very exact).
Use an 1k resistor in series with the diode.
Measure the voltage across the diode.

It should be somewhere 300mV ... 500mV.
Loo low voltage or too high voltage shows a defective diode.

Fortunately DMMs today have a diode test option so that you do not need to spend time for a simple diode test.

What characteristcs can you evaluate ?

Can you evaluate reverse voltage breakdown ?
Can you evaluate Idiode v.s. Vdiode with only DMM without DC signal source ?

Only forward voltage drop.
