Package TO-220AB Circuit Discrete Polarity N VBRDSS (V) 30 RDS(on) 10V (mOhms) 3.3 ID @ 25C (A) 240 ID @ 100C (A) 170 Qg Typ 130.0 Qgd Typ 41.0 Rth(JC) 0.45 Power Dissipation (W) 330 PbF - FETD PbF
Okay na siguro 'to sirs... 330w should be good enough....
tnx my friend!!!

Two test installations completed. Good results on the initial test firing. NO NOTICABLE HEAT build-up, even during long full auto strings. Of course, it does get warm after a while but not as HOT as the "lesser" MOSFETs we've tried.
My ROF also seems to have increased further... I got an ROF boost when I used mechanical relays, and another ROF boost when I tried the MOSFETs. NOt a dramatic boost- but noticable.
Will battle test these babies some more during the 7to7 games and the EB games. <--SYARO!!! Trial by FIRE!!!
Will be on the look out for:
Overheating of the Mosfet and wires Reduced battery life(due to mosfet consumption) overall durabilty
Stay Tuned

Two Mosfets damaged due to "katangaan". Wala namin na mount sa PCB- nangabali ang mga paa ng mosfets... sayanga uy!
One unit installed in an AK SLR burned up during torture testing. Three mags full auto non-stop... kaboom....
The one in my AUG is still working fine however... I used 6 mags during the 7to7 games.

sir sandman anong name/part number ng posted nyong specs?
btw, i found a good replacement (if not better), somewhere sa raon nya nakit-an (i'm form iligan city) hehehe. IRF1010N try nyo pa scout, been using it for few games na so far ok naman. Another alternative naman i got from cebu is SUP75N06.
specs of irf1010n
VDSS = 55V RDS(on) = 11mW ID = 85A
Goodluck soldiers!!!

Tanong nyo na lang kay sir Alakdan sir kasi nakalimutan ko na talaga. Pati yung PDF file ko ay nabura kasi nag-crash yung HD ng PC ko sa shop.. hehehe..
Kabisado ni sir Alakdan yan kasi siya ang pina-assemble ko... mas magaling ang soldering skillz niya sa akin eh... heheheh...

Sir Jo & Sir Stan. Nasunog tanan ako wiring. Ambot na unsa to. Nag melt ang selector plate unya ni pilit sya sa gearbox dapit sa may contact switch. Aso2 gud ako pusil ganina. Murag sunog pud ni akong motor kay itum2 man agi. Wala na koy pusil. Pastilan. Im planning to rewire everything. If the old motor can be salvaged, then better. Kabalo ko si sir Jo maka rewind ug motor na better than its stock form. If not, then mangita pa ko budget for a new one.
I need your help sirs.
I'll be posted. Tnx.

sir jo or any tech gurus, i have made a schematic of my connection...kung full auto...ok lang, kaso kung single...nahihirapan siya i-crank....
i tried it also w/out the fuse (thinking that 20amp is not enough)...same banana, wont fire at single....parang nag titrip siya...
ill be testing it this afternoon...before ko bubuksan ulit....hapit na baya ang tourney....haaaahahaaaaaay!
pls help...tia....

your schematic correct sir mikz but correct kaya yan sa actual...i mean the connection of wire that run to selector switch then to trigger switch...i want to see your gear box sir...diko pa natry ang mp5 but actual can help me how to do it... another one kung mosfet ang probs bakit umandar eto kung full auto? pero kung sakali gawa kita ng bago mmya... check this also: mp5and mp5kmejo tricky lang kay gipa agi pa nila ang positive sa sulod sa shrinkable tube... <<jojo>>

here's an update sir/s: after three mags of full-auto, i tried using the single shot...gumana naman sa awa ng dios...kaso lang...kapag na-rest na naman, nahihirapan na naman siyang i-crank sa single...so full-auto ulit...tapos balik single...hehehe
minsan, parang na-ooverkill ko tuloy ang kalaban kasi always full-auto nalang ginagamit ko...kesa ako ang maunahan...hehehe.
i'll try to invert the connection dun sa trigger switch, baka nandun lang talaga ang trick in installing the mosfet on a v2 gbx....
@sir jo, to give you an idea....dun sa site ng how to install on mp5, kung saan ang red wire sa trigger switch, ganun din ang pagkakabit ko sa akin...di ko lang talaga maintindihan kasi japanese...hehehe. ill try to open it tomorrow...{hopefully post some pix)...& give you guys update.
tyvm & good day.

Mga sir, Newbie lang mga sir, merom akong pics nang ginawa kong burst controller/MOSFET switch kaso lang di ko pa alam mag upload. Ginamit ko 'yung IRF3710 at 555 timer. Pwedeng i-bypass ang timer, 53x18x9 mm ang dimension. Tinesting ko na sa lab namin sa opisina kanina, walang problema! nico
