Talk:Semiconductor fuse

While the article mentions that semiconductor fuses are used to protect semiconductors ..are they themselves made of semiconductor materials as well? If so then we should park it in the Category:Semiconductor devices --Hooperbloob 16:38, 22 January 2006 (UTC)

No, they are made of thin pieces of metal just like any other fuse. The difference is that the geometry of the metal is such that they are extremely fast-acting. The term "semiconductor fuse" refers to the fact that they are suitable for protecting power semiconductors from hard short circuits. Power semiconductors (like SCRs, IGBTs, MOSFETs) are often able to handle very high voltages OR very high currents but not both at the same time for more than a few microseconds. If a short circuit happens in a system, this may try to force the semiconductor to withstand BOTH high voltage and high current at the same time. This fuse is intended to catch this condition and clear the fault before the semiconductor device is damaged. Sbreheny (talk) 15:40, 14 January 2013 (UTC)

Article probably should mention that these devices are more or less never found in consumer electronic equipment. Tabby (talk) 11:55, 5 December 2007 (UTC)

if anyone has a picture of the inside of one these fuses, please add it to this article.
