Re: HP 2009f no power
Looking at SR520 specifications, its a schottky barrier diode. Important stuff to look at are...Originally posted by kulokutoys View Post
Peak reverse voltage: 20V (or greater)
Average current: 5A (or greater)
Forward voltage: 0.55V (preferably equal, but can be less)
Peak current: 150A (or greater)
There are many diodes with those parameters such as SR502 and SB520. You can also use those with higher specifications such as SR503, SB530, SB540, SR1202, SR1203, SR1204, SR1245, etc...
