The Ware for September 2015 is a Powerex CM600HA-24H, which met its demise serving as a driver for a tesla coil in the Orage sculpture (good guess 0xbadf00d!). I have a thing for big transistors, and I was very pleased to be gifted this even though it was busted. At $300 a piece, it’s not something I just get up and buy because I want to wear it around as a piece of jewelry; but it did make for a great, if not heavy, necklace. And it was interesting to take apart to see what was inside!
As for the winner, Jimmyjo was the first to guess exactly the model of the IGBT. Congrats, email me for your prize!
