2N7000 MOSFET ndi gawo lomwe limagwiritsidwa ntchito kwambiri padziko lonse lapansi pazamagetsi, lomwe limadziwika chifukwa chodalirika, kuphweka, komanso kusinthasintha. Kaya ndinu injiniya, wokonda zosangalatsa, kapena wogula, kumvetsetsa 2N7000 ndikofunikira. Nkhaniyi ikulowera mozama muzochita zake, ntchito, ndi zofanana, ndikuwunikiranso chifukwa chake kupeza kuchokera kwa ogulitsa odalirika ngati Winsok kumatsimikizira ubwino ndi ntchito.

Kodi 2N7000 Transistor ndi chiyani?

2N7000 ndi MOSFET yamtundu wa N-channel, yomwe idayambitsidwa koyamba ngati chipangizo chazonse. Phukusi lake lophatikizana la TO-92 limapangitsa kukhala chisankho chabwino pamapulogalamu ochepera mphamvu. Makhalidwe akuluakulu ndi awa:

  • Low ON kukana (RDS (pa)).
  • Kugwira ntchito pamlingo womveka.
  • Kutha kunyamula mafunde ang'onoang'ono (mpaka 200mA).
  • Ntchito zosiyanasiyana, kuyambira kusintha mabwalo kupita ku amplifiers.

Zithunzi za 2N7000

Parameter Mtengo
Mphamvu yamagetsi yotchedwa Drain-Source Voltage (VDS) 60v ndi
Gate-Source Voltage (VGS) ± 20V
Continuous Drain Current (ID) 200mA
Kutaya Mphamvu (PD) 350mW
Kutentha kwa Ntchito -55°C mpaka +150°C

Zithunzi za 2N7000

2N7000 imakondwerera kusinthika kwake pamagwiritsidwe osiyanasiyana, kuphatikiza:

  • Kusintha:Amagwiritsidwa ntchito m'mabwalo osinthira mphamvu zochepa chifukwa chakuchita bwino kwambiri komanso nthawi yoyankha mwachangu.
  • Kusintha kwa Level:Ndibwino kuti muzitha kulumikizana pakati pamitundu yosiyanasiyana yamagetsi yamagetsi.
  • Zokulitsa:Imagwira ntchito ngati amplifier yamphamvu yotsika mumayendedwe omvera ndi ma RF.
  • Digital Circuits:Nthawi zambiri amagwiritsidwa ntchito pamapangidwe opangidwa ndi microcontroller.

Kodi 2N7000 Logic-Level Imagwirizana?

Inde! Chimodzi mwazinthu zoyimilira za 2N7000 ndikulumikizana kwake kwamalingaliro. Itha kuyendetsedwa mwachindunji ndi malingaliro a 5V, ndikupangitsa kuti ikhale yabwino kwa Arduino, Raspberry Pi, ndi nsanja zina za microcontroller.

Kodi Zofanana ndi 2N7000 Ndi Chiyani?

Kwa iwo omwe akufuna njira zina, zofananira zingapo zitha kusintha 2N7000 kutengera zofunikira zadera:

  • Chithunzi cha BS170Amagawana mawonekedwe amagetsi ofanana ndipo amagwiritsidwa ntchito mosinthana.
  • IRLZ44N:Zoyenera pazifukwa zapamwamba zamakono koma phukusi lalikulu.
  • 2N7002:Mtundu wapamwamba wa 2N7000, wabwino pamapangidwe apakatikati.

Chifukwa Chiyani Sankhani Winsok Pazosowa Zanu za MOSFET?

Monga wogawa wamkulu wa Winsok MOSFETs, Olukey amapereka khalidwe losayerekezeka ndi lodalirika. Timaonetsetsa kuti:

  • Zowona, zogwira ntchito kwambiri.
  • Mitengo yampikisano yogula zambiri.
  • Thandizo laukadaulo kukuthandizani kusankha gawo loyenera.

Mapeto

2N7000 transistor imadziwika kuti ndi yolimba komanso yosunthika pamapangidwe amakono amagetsi. Kaya ndinu mainjiniya wodziwa ntchito kapena wongoyamba kumene, mawonekedwe ake, kugwirizana kwamalingaliro, ndi mitundu ingapo yamapulogalamu zimapangitsa kuti musankhe. Onetsetsani kuti mumapeza ma 2N7000 MOSFETs anu kuchokera kwa ogulitsa odalirika ngati Winsok kuti mugwire bwino ntchito komanso kudalirika.
