Replacement diode for inverter, help needed
« on: January 15, 2021, 07:35:49 pm »
I need a replacement diode for the inverter I am trying to fix.  I'm guessing its a beefy schottky diode, my dmm says a VF of 460mv.  There's a double diamond logo and the diode has ER5026 on it.  Any idea what diode I should order to replace the blown one.  Also if I just replace one is my efficency going to be crap because the (some type of rectifier) well matched?

Vf is 1.0V at 5.0A.
Thanks thats it!
It doesn't look like I can buy those anymore, but I'm thinking this guy will do the job, different package and higher current rated.  Any thoughts?

That looks electrically OK. However, I would think that it shouldn't be too hard to find a replacement diode in the same package. :-?

I had a hard time finding one that met the same Reverse recovery time Trr for the given If and Reverse voltage.

Did you ever find a replacement for the ER5026?  I think we're all looking to fix the same Xantrex inverter or its equivalent.  I found one hard shorted diode of 24.
