(1) MOSFET chinhu chinokonzeresa-voltage, nepo transistor chinhu chiripo-chekuita. Mukukwanisa kutyaira hakupo, dhiraivha ikozvino idiki kwazvo, inofanira kusarudzwaMOSFET; uye muchiratidzo voltage yakaderera, uye akavimbisa kutora zvakawanda ikozvino kubva yemagetsi hove muchina dhiraivha danho mamiriro, inofanira kusarudzwa transistor.
(2) MOSFET ndiko kushandiswa kwevazhinji vatakuri conductive, inodaidzwa kuti unipolar mudziyo, nepo transistor iri kuti kune ruzhinji rwevatakuri, asi zvakare kushandiswa kwenhamba shoma yevatakuri conductive. Inonzi bipolar device.
(3) VamweMOSFET tsime uye dhiraivha inogona kuchinjaniswa kushandiswa kwegedhi voltage inogona kuva yakanaka kana yakaipa, iyo inoshanduka kupfuura iyo transistor yakanaka.
(4) MOSFET inogona kushanda mudiki diki uye yakaderera voltage mamiriro, uye maitiro ayo ekugadzira anogona kuve nyore kubatanidza maMOSFET mazhinji musilicon chip, saka maMOSFET mumaseketi makuru akasanganiswa akashandiswa zvakanyanya.
(5) MOSFET ine mabhenefiti epamusoro ekuisa impedance uye yakaderera ruzha, saka inoshandiswa zvakanyanya mumhando dzakasiyana dzemagetsi tepi michina. Kunyanya nemunda mhedzisiro chubhu kuita iyo yese yemagetsi midziyo yekupinza, yekubuda nhanho, inogona kuwana iyo general transistor yakaoma kusvika pabasa.
(6)MOSFETs akakamurwa kuita mapoka maviri: red junction type uye insulated gedhi mhando, uye misimboti yavo yekunyengera yakafanana.
Muchokwadi, iyo triode yakachipa uye iri nyore kushandisa, inowanzoshandiswa mune yekare-yakaderera-frequency vabati vehove, MOSFET ye-high-frequency high-speed circuits, high-current-nguva, saka rudzi rutsva rwepamusoro-frequency ultrasonic fishers, inokosha. ndiyemukuru MOS. kazhinji kutaura, nguva yakaderera-mutengo, kushandiswa kwese kwekutanga kufunga nezve kushandiswa kwe transistors, kwete kana iwe uchida kufunga nezve MOS.
MOSFET zvikonzero zvekuputsika uye mhinduro dzinotevera
Chekutanga, kupikisa kwekupinza kweMOSFET pachayo kwakakwira zvakanyanya, uye gedhi - sosi ye-inter-electrode capacitance idiki kwazvo, saka inotapukirwa nekunze kwemagetsi emagetsi minda kana electrostatic inductance uye kubhadhariswa, uye mari shoma inogona kuumbwa. mu inter-electrode capacitance yeyakakodzera high voltage (U = Q / C), ichakuvadzwa chubhu. Kunyangwe iyo MOS yekuisa yemuchina wemagetsi wekubata hove ine anti-static kugadzirisa matanho, asi ichiri kuda kurapwa zvine hungwaru, mukuchengetedza uye kuendesa emhando yepamusoro midziyo yesimbi kana conductive zvinhu kurongedza, usaise nyore kurwisa static high voltage. makemikari zvinhu kana makemikari fiber machira. Gungano, kutumwa, zvinhu, chitarisiko, nzvimbo yekushandira, nezvimwe zvinofanirwa kuve zvakatanhamara. Kuti udzivise kukanganiswa kwemugadziri wemagetsi emagetsi, senge kusapfeka naironi, mbatya dzekemikari fiber, ruoko kana chimwe chinhu usati wabata chivharo chakabatanidzwa zviri nani kubatanidza pasi. Kumichina inotungamira kutwasanudza uye kukotama kana manual welding, kushandiswa kwemidziyo kunodiwa kune yakasarudzika pasi.
Chechipiri, iyo diode yekugadzirisa pakuiswa kweseketi yeMOSFET, kushivirira kwayo panguva-yazvino kunowanzo kuve 1mA mukukwanisa kwekuwedzera kwechinguva chidiki chekupinza ikozvino (kupfuura 10mA), inofanirwa kuve yakabatana neiyo yekuisa yekuchengetedza inodzivirira. Uye 129 # mukutanga dhizaini haina kutora chikamu mukugadzirisa gadziriso, saka ichi ndicho chikonzero nei MOSFET inogona kuparara, uye nekutsiva yemukati inodzivirira MOSFET inofanira kukwanisa kudzivirira kutanga kwekutadza kwakadaro. Uye nekuti dunhu rekugadzirisa kuti ritore simba rechinguva ridiki, yakawandisa chiratidzo chechinguvana uye yakawandisa electrostatic voltage ichaita kuti dunhu rekugadzirisa rishaye simba. Saka kana welding soldering iron inodiwa kuti isimbiswe zvakasimba kudzivirira kudonha kwemidziyo yekuputsika, kushandiswa kwese, kunogona kudzima mushure mekushandiswa kwekupisa kwasara kwesimbi yekunyungudika, uye kutanga weld mapini ayo akaiswa pasi.
