Hey guys,
I just have a quick question regarding a fuse I'd like to use for a mosfet.
A little bit about my project:
I am making something for driving LED strips. However I'd like to protect the mosfets in case someone accidentally shorts out the strips. The mosfet I am using is the BUK7880-55A. The mosfet drain current is rated at 7 amps. I will be using well below that. The power source I am using is limited at 10Amps so if a short does happen, 10amps will be going through the mosfet briefly until the fuse blows.
Here is my issue... below is the absolute maximum rating of the moset for a quick pulse. It says 30Amps with a test condition of <10uS.
DM peak drain current Tsp = 25 °C; pulsed; tp ≤ 10 µs; Fig. 3 - 30 A
Im trying to choose a fuse, and I am looking at the P15131TR-ND on digikey. It says its fusing time is 100uS. Does this mean I can possibly still damage the mosfet? Are there faster fuses out there than can blow under 10uS? Any help is appreciated. Thanks!
