The high current rating of the actual silicon I guess is for assurance (and pulse applications where the leads survive high current momentarily.) Anyone putting 300A continuously through a TO220 is in for a bad time. |

I wonder if they are using the same silicon die in their TO220 as their PowerSOIC(8-DFN 5x6). Might explain where the ratings come from. |

I think I had one of those 300 A, TO-220 transistors once. I believe my fingerprint is still melted into it. Not a joke. Real fingerprint in whatever the plating alloy was. OUCH! And it did survive and continue to operate! So did my finger. --- Quote from: tom66 on January 05, 2024, 12:40:04 pm --- --- Quote from: Psi on January 05, 2024, 11:35:05 am ---Did it say 300A continuous though? --- End quote --- Indeed, every time I've seen those very high power FETs it notes that the current is limited by the package first.
