00:00If you've ever blown up a transistor mid-project and realized you don't have a single spare in
00:04the drawer, this one's for you. I spent way too many hours digging through listings, comparing
00:09specs, reading reviews, and I finally narrowed it down to the 5 best MOSFET transistor assortment
00:14boxes for Arduino builds right now. These are the ones that actually give you the parts you'll use,
00:20at prices that won't make you wince. Let's get into it.
00:24First up is the 50-piece, 10-type assortment with the IRF640, IRF740, IRF830, IRF840, IRF530,
00:34IRF630, IRF820, IRFZ44, IRF9540, and IRF3205. And honestly, that lineup is the reason this one
00:42is my top pick. You've got the IRFZ44 and IRF3205 for low-voltage, high-current switching, which is
00:49exactly what you want for motors, LED strips, and battery projects, plus the IRF9540 if you need a
00:55P-channel for high-side switching. $12.72 for 50 parts, over 4,500 sold, and a perfect 5-star
01:03rating.
01:04If you only buy one box, make it this one.
01:08Number 2 switches things up with a high-voltage focus, 50 pieces, 10 types, all 2-220,
01:13covering the 2-in-60 through 20-in-60 range, plus the 13003, the MBR20100 shotkey diode and a 75
01:22-NF75.
01:23This is the kit you want if you're messing with switch-mode power supplies, LED drivers,
01:28or repairing chargers and adapters, because those 600-volt parts are exactly what fail in that gear.
01:34$15 flat, 4.8 stars, and the fact that they threw a rectifier diode in there tells you someone
01:39actually thought about what a repair bench needs. Third is the budget champion, and I mean seriously
01:45budget. $2.55 gets you 10 assorted 600-volt N-channel MOSFETs in the 2-220F insulated package,
01:53spanning 2-in-60 all the way up to 20-in-60, with the 18-in-50 and 7-in
01:58-65 in there too.
02:0010 pieces isn't a lifetime supply, but that insulated tab means you can bolt them straight
02:04to a grounded heatsink without a mica washer, which saves real hassle.
02:095-star rating, over 4,000 sold. If you just want to try a few high-voltage parts without committing,
02:15this is a no-brainer. Fourth up is the premium option, a 50-piece 2-220 kit with 10 values
02:21built
02:21around the heavy hitters, the IRF-Z44N, IRF-540N, IRF-3205 and IRF-640N. Yes, 2566 is the most expensive
02:31on this list, but the whole selection here is tilted toward logic-level friendly, high-current
02:36switching, the stuff Arduino people actually reach for. No wasted drawer space on parts
02:42you'll never touch. 5 stars, 4,000 plus sold, and if you're building motor drivers or powerboards
02:48regularly, the cost-per-useful part actually works out better than the cheap kits.
02:53And rounding it out at number 5, another 50-piece, 10-type IRF assortment, but this one swaps in the
02:58IRF-510, IRF-520 and IRF-540 alongside the IRF-640, IRF-740, IRF-830, IRF-840, IRF-530, IRF
03:08-630
03:08and IRF-820. That IRF-520 and IRF-540 combo was a big deal because those are the exact parts
03:15in
03:15about 90% of Arduino tutorials and breakout modules online. $15.04, 4.8 stars. Grab this one if you're
03:25following along with projects and want the parts the guides actually call for.
