Kumvetsetsa 2N7000 MOSFET

TO-92_2N7000.svg2N7000 ndi njira yotchuka ya N-channel MOSFET yomwe imagwiritsidwa ntchito kwambiri pamapangidwe apakompyuta. Tisanalowe mu kukhazikitsa kwa LTspice, tiyeni timvetsetse chifukwa chake gawo ili ndilofunikira pamagetsi amakono.

Zofunikira za 2N7000:

  • Mphamvu Yambiri Yakukhetsa-Magwero: 60V
  • Mphamvu Yambiri Yachipata-Magwero: ± 20V
  • Kukhetsa kosalekeza Panopa: 200mA
  • Kukanika Kwambiri: Nthawi zambiri 5Ω
  • Liwiro Losintha Mwachangu

Upangiri wapapang'onopang'ono pakuwonjezera 2N7000 mu LTspice

1. Kupeza Chitsanzo cha SPICE

Choyamba, mufunika mtundu wolondola wa SPICE wa 2N7000. Ngakhale LTspice imaphatikizapo mitundu yoyambira ya MOSFET, kugwiritsa ntchito mitundu yoperekedwa ndi opanga kumatsimikizira zofananira zolondola.

2. Kuyika Chitsanzo

Tsatirani izi kuti muyike mtundu wa 2N7000 mu LTspice:

  1. Tsitsani fayilo ya .mod kapena .lib yomwe ili ndi mtundu wa 2N7000
  2. Lembani fayilo ku laibulale ya LTspice
  3. Onjezani choyimira kuchifaniziro chanu pogwiritsa ntchito malangizo a .include

Zitsanzo Zoyeserera ndi Ntchito

Basic Switching Circuit

5jd3AChimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri ndi 2N7000 ndikusintha mabwalo. Umu ndi momwe mungakhazikitsire kayesedwe koyambira kosinthira:

Parameter Mtengo Zolemba
VDD 12 V Kukhetsa mphamvu yamagetsi
VGS 5V Geti-source voltage
RD 100Ω pa Kukhetsa resistor

Kuthetsa Mavuto Odziwika

Mukamagwira ntchito ndi 2N7000 ku LTspice, mutha kukumana ndi zovuta zingapo. Nayi momwe mungayankhire:

Mavuto Odziwika ndi Mayankho:

  • Mavuto a convergence: Yesani kusintha magawo a .options
  • Zolakwika zotsitsa zachitsanzo: Tsimikizirani njira yamafayilo ndi mawu
  • Khalidwe losayembekezereka: Yang'anani kusanthula kwa malo ogwirira ntchito

Chifukwa Sankhani Winsok MOSFETs?

Winsok 2N7000 MOSFETsKu Winsok, timapereka ma MOSFET apamwamba kwambiri a 2N7000 omwe ndi:

  • 100% adayesedwa ndikutsimikiziridwa kuti ndi yodalirika
  • Mtengo wampikisano wamaoda ang'onoang'ono ndi akulu
  • Likupezeka ndi zolemba zonse zaukadaulo
  • Mothandizidwa ndi gulu lathu laukadaulo la akatswiri

Kupereka Kwapadera kwa Akatswiri Opanga Mapangidwe

Tengani mwayi pamitengo yathu yapadera yamaoda ochulukirapo ndikupeza zitsanzo zaulere pazosowa zanu zama prototyping.

Mfundo Zapamwamba Zogwiritsira Ntchito

Onani mapulogalamu apamwamba awa a 2N7000 pamapangidwe anu:

1. Magawo Osuntha Magawo

2N7000 ndiyabwino kwambiri pakusintha magawo pakati pa madera osiyanasiyana amagetsi, makamaka pamakina osakanikirana amagetsi.

2. Madalaivala a LED

Phunzirani momwe mungagwiritsire ntchito 2N7000 ngati woyendetsa bwino wa LED pazowunikira zanu.

3. Ntchito Zomvera

Dziwani momwe 2N7000 ingagwiritsire ntchito pakusintha ma audio ndikusakaniza mabwalo.

Thandizo laukadaulo ndi Zida

Pezani zida zathu zaukadaulo:

  • Tsatanetsatane datasheet ndi zolemba ntchito
  • LTspice model library ndi zitsanzo zoyeserera
  • Malangizo a mapangidwe ndi machitidwe abwino
  • Thandizo laukadaulo la akatswiri

Mapeto

Kugwiritsa ntchito bwino 2N7000 mu LTspice kumafuna chidwi ndi tsatanetsatane komanso kasinthidwe koyenera kachitsanzo. Ndi kalozera uyu ndi chithandizo cha Winsok, mutha kuwonetsetsa zoyeserera zolondola komanso magwiridwe antchito abwino kwambiri.
