Only comes in a 4 device wide, 16 pin dip at digikey. > > 150 MA 300V output (abs max) > Thanks Peter, I wound up getting the tsop TLP127 as I can carve a quick pcb for it on the mill. Quick & dirty, no eagle involved, but functional for a "onesie". Now, if I could just find a 3x higher voltage version of the IRFP250N hexfet with about the same gate driving capacitance load. The 200v I managed to punch thru a couple days back. Thats a 35 amp device, and there is a 78 amp 650 volter available but I wasn't able to compare gate input capacitance. But I'd bet that 78 amp puppy is 10x the 30 amp version. Sadly, my 8+feet of semi manuals is now pushing 15 to 20 years out of date.
