Ungasarudza sei MOSFET?

1. Ziva Rudzi

 

-N-channel kana P-channel: Sarudza pakati peN-channel kana P-channel MOSFET yakavakirwa padunhu dhizaini. Kazhinji, N-channel MOSFETs inoshandiswa kune yakaderera-side switching, nepo P-channel MOSFETs inoshandiswa kune yakakwira-side switch.

 

2. Voltage Ratings

 

-Maximum Drain-Source Voltage (VDS): Sarudza iyo yakanyanya drain-to-source voltage. Ukoshi uhwu hunofanira kudarika iyo chaiyo voltage kushushikana mudunhu rine yakakwana margin yekuchengetedza.

-Maximum Gate-Source Voltage (VGS): Ita shuwa kuti MOSFET inosangana nezvinodiwa nevolti yedunhu rekutyaira uye haipfuure gedhi-source voltage muganho.

 

3. Ikozvino Kugona

 

- Yakatemerwa Yazvino (ID): Sarudza MOSFET ine yakayerwa ikozvino yakakura kupfuura kana yakaenzana neyakakura inotarisirwa ikozvino mudunhu. Funga nezve pulse peak ikozvino kuti uone kuti MOSFET inogona kubata yakanyanya ikozvino pasi pemamiriro aya.

 

4. On-Resistance (RDS(on))

 

- Pa-Kupokana: Iko-kupokana ndiko kuramba kweMOSFET kana ichiitisa. Kusarudza MOSFET ine yakaderera RDS (pa) inoderedza kurasikirwa kwemagetsi uye inovandudza kushanda zvakanaka.

 

5. Kushandura Performance

 

-Kuchinja Kumhanya: Funga nezve switching frequency (FS) uye kusimuka / kudonha nguva dzeMOSFET. Kune yakakwirira-frequency application, sarudza MOSFET ine kukurumidza kuchinja maitiro.

- Capacitance: Iyo gedhi-dhiraini, gedhi-sosi, uye drain-source capacitances inokanganisa kukurumidza kukurumidza uye kugona, saka izvi zvinofanirwa kutariswa panguva yekusarudza.

 

6. Package uye Thermal Management

 

-Package Type: Sarudza yakakodzera pasuru mhando yakavakirwa paPCB nzvimbo, zvinodikanwa zvekupisa, uye maitiro ekugadzira. Saizi uye kushanda kwemafuta kwepakeji kuchapesvedzera kukwira uye kutonhora kweMOSFET.

- Thermal Zvinodiwa: Ongorora iyo system yekupisa zvinodiwa, kunyanya pasi pemamiriro ezvinhu akaipisisa. Sarudza MOSFET inogona kushanda zvakajairika pasi pemamiriro aya kudzivirira kutadza kwehurongwa nekuda kwekupisa.

 

7. Temperature Range

 

-Iva nechokwadi chekuti tembiricha yekushandisa yeMOSFET inoenderana nezvinodiwa zvezvakatipoteredza zvehurongwa.

 

8. Mafungiro Akakosha Ekushandisa

 

- Yakaderera-Voltage Zvishandiso: Kune maapplication anoshandisa 5V kana 3V magetsi ekushandisa, nyatsoteerera kune iyo MOSFET's gedhi voltage miganho.

-Wide Voltage Applications: A MOSFET ine yakavakirwa-mukati Zener diode inogona kudikanwa kudzikamisa gedhi voltage swing.

- Dual Voltage Zvishandiso: Yakakosha dhizaini dhizaini inogona kudikanwa kudzora yakakwira-parutivi MOSFET zvinobudirira kubva pasi-parutivi.

 

9. Kuvimbika uye Unhu

 

- Funga nezvemukurumbira wemugadziri, kuvimbiswa kwemhando, uye kugadzikana kwenguva refu kwechikamu. Kune yakakwirira-yakavimbika maapplication, mota-giredhi kana mamwe maMOSFET akasimbiswa anogona kudiwa.

 

10. Mutengo uye Kuwanikwa

 

- Funga nezve mutengo weMOSFET uye nguva yekufambisa yemutengesi uye kugadzikana kwekupa, kuve nechokwadi chekuti chikamu chinosangana nekuita uye bhajeti zvinodiwa.

 

Pfupiso Yematanho eKusarudza:

 

- Sarudza kana N-chiteshi kana P-chiteshi MOSFET ichidiwa.

-Gadzira iyo yakanyanya drain-source voltage (VDS) uye gedhi-sosi voltage (VGS).

-Sarudza MOSFET ine yakayerwa ikozvino (ID) inogona kubata peak currents.

-Sarudza MOSFET ine yakaderera RDS (pa) yekuvandudza kugona.

- Funga nezve MOSFET's switching kumhanya uye mhedzisiro yecapacitance pakuita.

-Sarudza yakafanira pasuru mhando zvichienderana nenzvimbo, zvinodikanwa zvekupisa, uye PCB dhizaini.

-Iva nechokwadi chekuti tembiricha yekushandisa inoenderana nezvinodiwa nehurongwa.

-Akaundi yezvakakosha zvinodiwa, senge voltage kudzika uye dhizaini dhizaini.

- Ongorora kuvimbika kwemugadziri uye mhando.

- Chinhu mumutengo uye kugadzikana kwekutengesa cheni.

 

Paunenge uchisarudza MOSFET, zvinokurudzirwa kubvunza dhatabheti yemudziyo uye kuita yakadzama yedunhu ongororo uye maverengero kuti uone kuti inosangana nemamiriro ese ekugadzira. Kuita masimulation uye bvunzo zvakare inhanho yakakosha yekuona chokwadi chesarudzo yako.
