Good morning to all.
I feel like a bit of an intruder but have joined the forum as I am desperate for an answer to what I expect many electronics specialist will find very basic (I am a retired mechanical engineer with a little electronics knowledge gained from an enquiring mind)
I have spent hours trying to identify what could be an IGBT on the heatsink of an induction hob Main board. The photo shows, from right to left a bridge rectifier, two identical 3 pin items ( these are the culprits) and an IGBT (H20 R12 03). The hob blew the 20 amp fuse and it looks to me like the two unidentified items also, they both show open circuit on the multimeter. The numbering on both is G281H125DF and B V5 632 and no amount of online searching recognises these numbers for me to get replacements. Can anyone help please, are they also IGBT's and if so, what alternative spec would be acceptable replacements. I should add that sharp cannot help me with supplying a new complete board (it's only 4 years old!) or offer help identifying the components.

Thanks for the reply and details. I have found plenty of sources for the H20 R12, are the other two with different ident numbers likely to be IGBT's as well and can I replace with two H20 12's ?
