Mounting mosfets back to back
Nettet2. nov. 2024 · The sink experienced a 22c rise. This was equaled by Bergquist K-10. Bergquist 1500ST performed notably better (5c lower temp) than the previous two. The mounting screw exhibited a 35c rise, though the final sink temperature was unchanged from the previous two runs and showed a 22c rise. Keratherm and Aluminum Oxide … NettetTwo N-channel MOSFETs are externally connected back-to-back (in a common-source configuration) when a load switch using a gate drive IC needs a function for blocking the current flowing into the load switch in the reverse direction. This function is called reverse-current blocking.

ON Semiconductor has introduced a Thermally Enhanced (TE) SO8−FL MOSFET portfolio in order to aid in this endeavor. The SO8−FL TE utilizes a different mold compound that has over 3.5 times the thermal conductivity of the standard SO8−FL mold compound. NettetWe invite you to learn more!

It takes two MOSFETs to form a bi-directional switch, one to control current in one direction, the other one for the other direction. If you had only one MOSFET, you would get a uni-directional switch: you could only be able to control current in one direction. rockport campground ut
