Schottky diode?

When i measure the resistance in a Schottky diode, what should i expect? I have one that when i do it --> that way has cero ohms and i think it is correct, but when i do it oposite, --< it has 500 K ohms. Is that correct? Becouse in any normal diode in one way it should have cero ohms and in the other allmost infinite ohms, the indicator in the multiteste should not even move a bit. Can any budy give me a hand? The diode is an IR 51HQ045. Thanks in advance! CLT.

I think it is fine lite that. Schottky diodes have a higher leakage curred compared to SI-diodes. To get a more interesting value than the "resistance", which will depend on your multimeter type, you might want to try a meter with a forward voltage check function. The schottky should be around 200mV and a SI around 700.
