Hi! Just wanted to share my experince. I received Orange Pi Zero Plus and it was a board without Q5 FET soldered. I could not find BSN20 FET, so I tried to check for an alternative. - First one to try and solder it was a SI2302 N-channel FET with marking A2SHB. This one was a failure. I could boot Armbian with nightly kernel 4.17.14, but armbianmon utility showed "---" instead of the CPU clock. And I was unable to boot kernel with "gpio-regulator-1.3v" "cpu-clock-1.3GHz" overlays, it just hanged soon after loading kernel modules. - The second one I found was 2N7002 N-channel FET with marking K72-P2 (this one I salvaged out of an old MoBo). And it was a success! Board was able to boot with overlays enabled and it runs fine with clocks up to 1300MHz, yay! Now my board works just fine, but it heats like hell under stress, even with a good heat sink. Thanks that throttling works just fine too. I think the diffrence in FETs is that we need one with lower Vgs threshold voltage than the one with higher drain current. Hope this could be useful to somebody. Thanks to everyone who made this tweak possible!
