80NF70 Transistor Replacement: Find & Buy Suitable Alternative for Voltage Converter

Hello,
A friend's voltage converter broke down. The measurements show that the element shown in the photo has been damaged. It is located even before the 24DC / 230AC transformer. There are two such elements in the system, one is working properly. On this, after desoldering, there is a short circuit on all legs. Does any of you know where I am able to buy a replacement?

Title changed from "BONF 70" / trymer01.

However, it is not the 80NF70 (mosfet) sometimes? After the photo you can see .... Here's the data for this mosa:

I bought a transistor on the Allegro, after the replacement everything works as it should.
Thank you for your help.
