00:00Fix Burnt Transistors with these 2-2-20 MOSFETs
00:04Dead MOSFET in your amplifier or motor driver?
00:07I went through the top-selling 2-2-20 kits so you don't have to.
00:11These are the deals I found for fixing burnt transistors with these 2-2-20 MOSFETs, 5 picks, all under
00:1715 bucks.
00:19First up, the IRFZ44N kit, 5-25 pieces depending on what you grab, 372, and that's the one I'd start
00:26with.
00:27This is the classic upgrade over the little 2N7000S people fry on cheap boards.
00:3355 volts, roughly 50 amps, low milli-ohm on resistance, and it drops right into a standard 2-2-20
00:39footprint with the same pinout.
00:41Over 4,000 sold, and the ratings are sitting at a flat 5 stars, which almost never happens.
00:47For money you want the single most versatile part in the drawer, this is it.
00:52Second is the 10-piece mixed pack for 470.
00:56This one opens the whole drawer in one order, IRF530N, IRF1404, IRF1405, IRF4905, IRF540N, IRF630N, IRF9540, IRF640, IRF840, plus the
01:09IRF530.
01:11You get a low-side switching chip, a 100-volt mid-range, a 200-volt for your flyback or boost
01:16stage, and a couple of P-channel parts for high-side switching.
01:20Ratings are a 4.3, mostly because people complain about the mixing, but that's the point, you need more than
01:26one type.
01:27If you repair a different board every weekend, this box pays for itself on the first job.
01:33Third, the IRF3205, and this is the bargain of the whole list at 234.
01:3955 volts, monstrous current handling, and it's the part most people actually mean when they say, the good MOSFET.
01:47IRF3205 is what ends up in everything from inverter welders to battery discharger boards.
01:52Nearly 4,200 sold, 4.9 rating.
01:56Buy 10 of these for the price of one coffee and you're set for the year.
02:00This is my personal default when a board dies and I don't want to think about it.
02:05Fourth, the 50-piece megabox, 10 different part types, 15 bucks, and honestly this is the best value per transistor
02:12you'll find.
02:13You've got the 2N60, 4N60, 5N60, 8N60, 10N60, 12N60, 20N60, 13003, MBR20100, and 75NF75.
02:26Heads up though, a lot of those 2N60 and 4N60 parts are actually IGBTs, not MOSFETs, and the MBR20100 is
02:34a shotkey rectifier, so double-check what you're soldering.
02:37But for anyone building power supplies, amplifiers, or inverter circuits, having that range on the shelf saves a shipping fee
02:44every time.
02:462,400 sold, 4.9 rating.
02:50Skipped, per product safety notes, add when writing real repair guidance, gate resistors, gate drive voltage, dead time on half
02:56bridges, these parts are all standard gate, not logic level.
02:59to go.
03:00The Πι
03:00Terima kasih.
