The following design parameters gives a schematic with a 'Custom' diode, not stating as suggested partnumber.

How do I identify a suitable diode?

Hi Jon,

Can you provide the your exported WEBENCH share design link? The images you are trying to link are not showing up on this thread.

Regards,
Jimmy

Hi Jimmy

Apparently the images didn't work.

Here's a link to the design:

webench.ti.com/.../SDP.cgi

My load is actually only in the low uA range, so I've preliminary selected a schottky diode: www.diodes.com/.../ds30548.pdf

My input is a stable 5V, and size is of importance, and I need operating temp from -40 to +125degC ambient.

Best regards

Hi Jon,

You can choose any diode to satisfy your requirement. The "custom diode" in the inverting buck simulation is only meant as a placeholder for such. The specific diode that I used during bench testing for the inverting applicatoion is the 1N5821GOS 30V/3A through-hole diode. There is a surface mount flavor(PMEG3030EP) with similar specs.

Regards,

Jimmy
