Hi guys .. so I'm fairly confident I need to replace the left most MOSFET (its connected to the + pin next to D10) , my problem is the same as here : [www.printrbottalk.com] I'm not too sure what to buy , from the RAMPS wiki page it should be a N channel MOSFET STP55NF06L ........ do I need to find a MOSFET with that same part number ... or will others be alright ? I will be going to jaycar tonight (http://search.jaycar.com.au/search?p=Q&srid=S10-AUSYDR02&lbc=jaycar&ts=custom&w=mosfet&uid=932917828&method=and&isort=score&view=list&srt=0) would anything there do ? thanks so much https://reprap.org/forum/read.php?219,376095,376095#msg-376095 Wed, 15 Jul 2026 09:50:30 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?219,376095,690694#msg-690694 https://reprap.org/forum/read.php?219,376095,690694#msg-690694 santhana365 RAMPS Electronics Thu, 21 Jul 2016 09:45:03 -0400 https://reprap.org/forum/read.php?219,376095,377876#msg-377876 https://reprap.org/forum/read.php?219,376095,377876#msg-377876
If you can get either of those online, I'd say go for it.]]> Cefiar RAMPS Electronics Fri, 04 Jul 2014 00:52:34 -0400 https://reprap.org/forum/read.php?219,376095,376518#msg-376518 https://reprap.org/forum/read.php?219,376095,376518#msg-376518
I was hoping of getting it before the weekend (and picking it up), I would have to order those online .... so far I have had no trouble with the STP55NF06L (I'm pretty sure I shorted the heater which broke the mosfet I need to replace) , there is another local electronic store here , they have the STP55NF06 (no L) is that drastically different, should I just get the FDP8870 or the IRLB8743 online ?]]> Jerms.a320 RAMPS Electronics Tue, 01 Jul 2014 01:38:47 -0400 https://reprap.org/forum/read.php?219,376095,376449#msg-376449 https://reprap.org/forum/read.php?219,376095,376449#msg-376449
Note: A heatsink on the heated bed output MOSFET is still a good idea (as is a fan pointing at your RAMPS board), but you will not need as large a heatsink with either of these MOSFETs, as compared to the standard STP55NF06L's. One of the very small clip on ones should suffice.]]> Cefiar RAMPS Electronics Mon, 30 Jun 2014 19:26:10 -0400 https://reprap.org/forum/read.php?219,376095,376150#msg-376150 https://reprap.org/forum/read.php?219,376095,376150#msg-376150 Jerms.a320 RAMPS Electronics Mon, 30 Jun 2014 05:43:29 -0400 https://reprap.org/forum/read.php?219,376095,376139#msg-376139 https://reprap.org/forum/read.php?219,376095,376139#msg-376139 reprap.org]
