For the 24V to 5V circuit, the 1N5824 used in the LM2596 typical circuit, I would like to ask: Can SMBJ30A be used instead? In addition, is it necessary for a 5V circuit to use a diode with such a large rated voltage?

Generally, SMBJ series TVS tubes are not used instead, but SS14/SS24/SS34 can be used instead, depending on the output current!

SMBJ30A is a TVS tube, it cannot replace Schottky diode 1N5824. . .

1 No! Different performance;
2 If you can't use the large current output, you can use a low-power tube such as 1N5817 (SS12).
