I've been looking for the very same thing, & the only thing I can find is SMAJ14 400W SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR, they also do a bidirectional one too so check, I don't think it is a bidirectional you want as it has the Cathode stripe on the one on the V3F16 I do believe, I'm currently looking at some at the moment, it always seems to be the same two transistors in the IGBT unit that blow?? I will keep the forum posted.

See if this link works its the data sheet, or just type SMAJ14 into search engine

that's right. there is nothing relevant to control pannel.
be sure & do it.
thanks
It works. Less troubleshooting, less headaches.
Just a few connectors alteration needed.
As the parts are arranged in two sets of three and usually only one set of parts, in each of the two sets, blows up a good solution is to use a scrap board for parts.
However, the small parts are all obtainable from Farnell for example.
Typically:
U10 is a J312 opto coupler; Farnell part 1085048
D17 = BYG22D; Farnell part 1021749
D32 = "YW" or MMSZ5V1; Farnell part 1431291
D23 = "V3V" or MMSZ7V5;Farnell part 1431295 but no longer stocked
D26 = D23
D328 = BUHC312 = SMBJ18A an 18V TVS diode; Farnell part 9843990
R64 12 ohm
The coding of the parts may vary slightly depending on the particular maker.
Sometimes one or more of the 220 ohm resistors on the back of the board fails and, as a matter of course, change the 47uF caps associated with a blown up set of diodes, although these could be OK.
I have an idea that many faults originate at the three relays, for example if a pair of contacts welds together.
Remove the plastic lid from the IGBT module and you can see what has happened.
0026 and 103 generally A2 board is damaged 。
Recommended replacement KDL16。
the device under investigation failed because of a failure in the
IGBT driver circuit together with failures in the following components: U17, D37, D36, D328,U11, U2, D24 in MCDR board。.
