You can still get them at Rochester Elec for about $0.60
They have about 400
Well, I’m not trying to buy more, the truth is that I bought some from a non very reputable source and they have a production date of 641, so 41st week of 2006 and I’m trying to figure out if they were still in production that time or if they’re fake.
Yes, I guess that’s what I’ll have to end up doing, I also bought some IRFP150 and other Toshibas from the same website, I will have to test them hard and if they break, then lesson learned...
BTW, I tried the ones in Rochester Elec and I got into an infinite loop unable to add them to the cart, Min purchase is 401 and Max is 55... LOL
Thanks for everything Mr. Pass!!!
This reminds me of a DIY member that had a swap meet post some years back with a big lot of IRF040, the cans, the real deal. But wouldn't split them up! I have no idea what happened to them. Probably sitting somewhere now.. It still pains me!

I am seeing dates far more recent than 2006. Does not prove there was a batch made on your date but does not cry "foul!"

I built a lot of 12V switching power supplies for automotive audio using IRFP044, way back in the 1990s.
