Component Identification help

[PAULEL88]

Help please...trying to identify these 2 components.
No circuit drgs available.
This is from a 24Vdc hydraulic pump controller that was subjected to high voltage.
The WX78A is a Vishay component but cannot find a resource to find out what it is (possibly SMA by measurement).
Nothing to go on with the 103K..(possibly SMB by measurement). I'm assuming it's a diode of some kind.
Both components have shorted along with a couple of MOSFETS that I've been able to identify.
Thanks!

The one labelled 103K may be an inductor and therefore supposed to read as shorted when checked with a multimeter. Can you get a view of the side of that component?

The WX78A may be a TVS diode, as in the other thread that you started. I suggest that you work out the circuit around that component.

RE WX78A:

WX is the component code <-- this is the Vishay component you are looking for.

78A is the Date code

Thanks for that. You’re right (I think) that the 103K may be an inductor. There are similar ones on the board marked 681K and they have a resistance of 30 ohms. This corresponds with data I found on the net. I’m finding it difficult to source a like for like replacement for the 103K… I wouldn’t be replacing it if it wasn’t for the fact I ruined it in removing . Here’s a side view… nothing much to see though.

Finally had a bit more spare time, the WX part is SMAJ10CA (as per Diver300 - bi-directional TVS diode).

Also think the 103k part is probably an inductor.

Thanks for the info.
