| Sep 5 at 1:27 | comment | added | Kevin | @Neil_UK yes, I do have 4 independent loads. that was why I thought about this configuration might work. My load has an auto-cutoff at 2.2A, maybe I could use a 3A schottky diode instead. | |
| Sep 5 at 1:27 | comment | added | Kevin | @jpa Will take that into consideration and I will check the "ideal diode" option which Attie and you suggested. | |
| Sep 5 at 1:27 | comment | added | Kevin | @brhans I'll check that out thank you. | |
| Sep 5 at 1:21 | comment | added | Kevin | @Kubahasn'tforgottenMonica Thank you, i was exploring other alternatives. | |
| Sep 4 at 16:38 | comment | added | jpa | Remember to also consider the dissipated heat, which will be 4 watts or more. A MOSFET based "ideal diode" chip could be a better option. | |

| Sep 4 at 14:36 | comment | added | Attie | Or you could look into an "ideal diode", which typically uses a MOSFET. | |
| Sep 4 at 11:07 | comment | added | Neil_UK | If you really have 4 indepedent loads, each of which takes a max of 2A, then you don't have a problem. | |
| Sep 4 at 10:58 | comment | added | brhans | You'd probably be better-off with a dual diode in a single package, with each individual diode in the package rated for 5 or 6A, than with 4 individual diodes. A pair of diodes on the same internal die will share current far better than individual diodes ever can. | |
| Sep 4 at 9:37 | comment | added | Kuba hasn't forgotten Monica | I wonder what the volume of your product is. I have a sneaky feeling that the engineering time you spend asking that question, reading the answers, and pondering it, will cost more than the diodes will cost for the entire production run of the product. Are you making something that will sell in 10k+ quantities? Otherwise, “saving money” on the diode is actually wasting money for the business :) | |
