Ukuqonda i-2N7000 MOSFET

TO-92_2N7000.svgI-2N7000 yindlela ethandwayo yokuphucula isitishi se-N-MOSFET esetyenziswa ngokubanzi kuyilo lwe-elektroniki. Phambi kokuntywila kumiliselo lwe-LTspice, masiqonde ukuba kutheni eli candelo libalulekile kwizinto zombane zanamhlanje.

Iimpawu eziphambili ze-2N7000:

  • Ubuninzi be-Drain-Source Voltage: 60V
  • Ubuninzi beSango-Umthombo wombane: ± 20V
  • Utsalo oluqhubekayo lwangoku: 200mA
  • Ukuxhathisa okuphantsi: Ngokuqhelekileyo yi-5Ω
  • Ukutshintsha ngokukhawuleza Isantya

ISikhokelo seNyathelo ngeNyathelo sokuFaka i-2N7000 kwi-LTspice

1. Ukufumana iModeli yeSPICE

Okokuqala, uya kufuna imodeli ye-SPICE echanekileyo ye-2N7000. Ngelixa i-LTspice ibandakanya ezinye iimodeli ezisisiseko ze-MOSFET, ukusebenzisa iimodeli ezibonelelwe ngumenzi kuqinisekisa ukulinganisa okuchanekileyo.

2. Ukufakela iModeli

Landela la manyathelo ukufaka imodeli ye-2N7000 kwi-LTspice:
