These aren't MOSFETs, these are MONSTER FETs. An extra beefy version of my other MOSFET breakout board - All of these fets are rated for 100A continuous drain current as long as you can keep them cool. The board is designed such that you can fit heatsinks on without blocking the installation of screw terminals, if you need it. Unlike the previous incarnation of this board, this board should be able to handle the full 100A (though the FETs will need both heatsinks and a fan if you are handling such heavy loads continuously) - we have measured the resistance between Gnd and the drain of the FETs as 0.6 milliohms.
If you need a larger quantity of a version than I have in stock, send me a message and I can have them assembled within a few days; the limited stock is to make sure I don't make piles of an unpopular version, leaving me without parts to build more of a popular version.
This board is manufactured on 2oz copper, with wide traces on both sides to carry both current and to help dissipate heat from the MOSFETs. The board can accept screw terminals on either 0.2" pitch pins - the small green screw terminals readily available from Chinese suppliers, or larger screw terminals on 9.5mm pitch pins. Note that even the larger screw terminals are only available rated up to 40A. Heavier loads require soldering a suitable wire directly onto the board; large exposed pads are provided for that purpose. There are two sets of mounting holes on the top - the one on the tabs (which can be broken off to fit into tight spaces) are for when large screw terminals are used, as they would cover up the other set of mounting holes.
Overall board dimensions are 2" x 2" with the mounting tabs, 2" x 1.75" with them removed.
Where the required current exceeds the specified maximum continuous current, heatsinks should be used. We offer optional heatsinks; if you choose for us to install them, they will be attached with thermal epoxy. This is done to order, and will add 1-2 days to order processing to allow the epoxy to set. For particularly heavy loads, a fan can be used as well - even a small amount of airflow makes a big difference.
For more demanding use cases - particularly where the logic level of the microcontroller isn't high enough for the 4.5v required on the high voltage versions, or where a heavy load is being rapidly switched (ie, PWM'ed, particularly at high frequency), we offer a version with a pair of NCP81071B gate drivers. These are capable of delivering the brief pulses of current into the gate needed to rapidly switch the MOSFET on or off. A voltage on the input lower than 0.8v is guaranteed to be treated as a low, and higher than 2.2v is guaranteed to be treated as high. These require at least 5v power supply on the V+ pin, and up to 20v (12v absolute max with the BSC026N02 fets, no more than 10v recommended) can be used (a higher voltage will give a lower on-state resistance).
Datasheet: BSC026N02 Rds: 3.5~4.3 mOhm @ 2.5 Vgs, 2.1~2.6 @ 4.5Vgs Vds: 20V max Current: Up to 100A continuous with added cooling, 25A max w/out.
Datasheet: BSC082N10LS Rds: 8.2~11 mOhm @ 4.5 Vgs, 6.8~8.2 @ 10Vgs Vds: 100V max
Current: Up to 100A continuous with added cooling, 14A max w/out. Note: The BSC082N10LS is marked as "not for new designs" indicating that the manufacturer intends to discontinue it - the best substitute I have found is the DMT10H010LPS, which is not quite as good. I will continue offering these as long as I am able to get them.
Datasheet: DMT10H010LPS Rds: 10~20 mOhm @ 4.5 Vgs, 6.9~8.3 @ 10Vgs Vds: 100V max
Current: Up to 98A continuous with added cooling, 9.4A max w/out.

United States Postal Service: Priority Mail - Flat rate (fastest, tracked)
Domestic shipping via USPS Priority Mail - USPS advertises 1~3 day shipping time within the continental United States. This is a flat rate for any quantity of items - this is your chance to buy piles of small cheap items like my mini prototyping boards without paying extra for shipping!
United States Postal Service: Priority Mail Express
The absolute fastest domestic service offered by the postal service. This is typically one day faster than Priority; but as you can see, that is a very expensive day. Orders placed via this shipping method will be given top priority in handling.
