2. I-LED Driving and Lighting Control

Izici zokushintsha ngokushesha ze-2N7000 ziyenza ibe yinhle kakhulu ezinhlelweni zokulawula i-LED:

Ukulawula ukukhanya kwe-PWM LED
Ukushayela kwe-matrix ye-LED
Ukulawula ukukhanya kwenkomba
Amasistimu okukhanyisa alandelanayo

I-LED yamanje (mA)	I-RDS enconyiwe(ivuliwe)	Ukuchithwa kwamandla
20mA	5Ω	2mW
50mA	5Ω	12.5mW
100mA	5Ω	50mW

3. Izicelo Zokuphatha Amandla

I-2N7000 isebenza ngempumelelo ezimeni ezahlukahlukene zokuphatha amandla:

Ukulayisha ukushintsha
Amasekhethi okuvikela ibhethri
Ukulawulwa kokusabalalisa amandla
Ukuqaliswa okuthambile kokuqala

Ukucatshangelwa Okubalulekile

Uma usebenzisa i-2N7000 ezinhlelweni zamandla, hlala ucabangela isilinganiso samanje esiphezulu esingu-200mA futhi uqinisekise ukuphathwa okwanele kokushisa.

Imicabango Yokusebenzisa Okuthuthukile

Izidingo ze-Gate Drive

I-gate drive efanele ibalulekile ekusebenzeni kahle kwe-2N7000:

I-voltage yesango elincane: 4.5V ukuze kuthuthukiswe ngokugcwele
I-voltage ephezulu yesango: 20V (ubukhulu obuphelele)
I-voltage yesango elijwayelekile: 2.1V
Ukushaja kwesango: cishe 7.5 nC

Ukucatshangelwa Okushisayo

Ukuqonda ukuphathwa kwe-thermal kubalulekile ekusebenzeni okuthembekile:

Ukumelana nokushisa kwe-Junction-to-ambient: 312.5°C/W
Izinga lokushisa eliphezulu lokuhlangana: 150°C
Ibanga lokushisa elisebenzayo: -55°C kuya ku-150°C
