Hey everyone,

I have a power supply that's busted and I've traced it down to a couple diodes. One is a zener that I was able to identify but the other one I'm not too sure of. There is PH4148 written on it but when I google that I just keep getting redirected to 1N4148 high speed switching diode, are these two parts interchangeable?

The power supply is a meanwell SP-320-24. The diode in question is right after the DC rectification and I'm sure it's part of the switching stage which leads me to believe it's a high speed switching diode but I hate to assume.

Hi foTONICS,
You can safely say they are the same from a different manufacturer.
PH was Philips. There are others too with different letters.
