Isesengura RYANANI CYANE: Gusobanukirwa, Gukumira, nigisubizo

Igihe cyo kohereza: Ukuboza-13-2024

Incamake yihuse:MOSFETs irashobora kunanirwa kubera ibibazo bitandukanye byamashanyarazi, ubushyuhe, nubukanishi. Gusobanukirwa nuburyo bwo kunanirwa ningirakamaro mugushushanya sisitemu yizewe ya elegitoroniki. Aka gatabo karambuye kerekana uburyo rusange bwo kunanirwa hamwe ningamba zo gukumira.

Impuzandengo-ppm-ya-Binyuranye-MOSFET-Kunanirwa-UburyoBisanzwe MOSFET Kunanirwa nuburyo butera imizi

1. Kunanirwa na voltage

  • Irembo rya okiside
  • Kumeneka kw'imvura
  • Gukubita
  • Ibyangiritse

2. Kunanirwa bijyanye nubushyuhe

  • Isenyuka rya kabiri
  • Guhunga ubushyuhe
  • Gusiba
  • Kuzamura insinga
Uburyo bwo kunanirwa Impamvu Zibanze Ibimenyetso byo kuburira Uburyo bwo kwirinda
Irembo rya Oxide Kumeneka VGS ikabije, ibyabaye muri ESD Kwiyongera kw'irembo Kurinda amarembo ya voltage, ingamba za ESD
Guhunga Ubushyuhe Gukwirakwiza imbaraga nyinshi Kuzamuka ubushyuhe, kugabanya umuvuduko wo guhindura Igishushanyo mbonera gikwiye, gutesha agaciro
Kumeneka kw'ibiza Umuvuduko wa voltage, guhinduranya inductive Umuyoboro uturuka kumasoko magufi Inzira ya Snubber, clamps

Ibisubizo bikomeye bya Winsok

Igisekuru cyanyuma cya MOSFETs kiranga uburyo bwo kurinda umutekano:

  • Kuzamura SOA (Agace gakorerwamo umutekano)
  • Kunoza imikorere yubushyuhe
  • Kwubaka muri ESD kurinda
  • Ibishushanyo mbonera bya Avalanche
Shakisha Urutonde rwa MOSFET Irinzwe

Isesengura rirambuye ryuburyo bwo kunanirwa

Irembo rya Oxide Kumeneka

Ibipimo by'ingenzi:

  • Irembo ntarengwa-Inkomoko ya Voltage: ± 20V isanzwe
  • Irembo rya Oxide Irembo: 50-100nm
  • Kumeneka Umwanya Imbaraga: ~ 10 MV / cm

Ingamba zo gukumira:

  1. Shyira mu bikorwa amarembo ya voltage
  2. Koresha urukurikirane rw'irembo
  3. Shyiramo diode ya TVS
  4. Imyitozo ikwiye ya PCB

Gucunga Ubushyuhe no Kurinda Kunanirwa

Ubwoko bw'ipaki Ikigereranyo Cyinshi Basabwe Gutanga Gukonjesha
TO-220 175 ° C. 25% Heatsink + Umufana
D2PAK 175 ° C. 30% Umwanya munini wumuringa + Ubushyuhe bwo guhitamo
SOT-23 150 ° C. 40% PCB Umuringa

Inama zingenzi zubushakashatsi kuri MOSFET Yizewe

Imiterere ya PCB

  • Kugabanya agace kazengurutswe
  • Tandukanya imbaraga nibimenyetso byerekana
  • Koresha Kelvin isoko ihuza
  • Hindura uburyo bwo gushyushya ibintu

Kurinda Inzira

  • Shyira mu bikorwa ibintu byoroshye
  • Koresha ibisumizi bikwiye
  • Ongeraho kurinda voltage
  • Kurikirana ubushyuhe bwibikoresho

Uburyo bwo Gusuzuma no Kwipimisha

Shingiro Shingiro rya MOSFET

  1. Ikizamini gihamye
    • Irembo ryinjira mumarembo (VGS (th))
    • Drain-source on-resistance (RDS (kuri))
    • Irembo risohoka (IGSS)
  2. Ikizamini Cyiza
    • Guhindura ibihe (ton, toff)
    • Ibiranga amarembo
    • Ubushobozi bwo gusohoka

Serivisi zo Kwizerwa kwa Winsok

  • Isubiramo ryuzuye rya porogaramu
  • Isesengura ryubushyuhe no gukora neza
  • Ikizamini cyo kwizerwa no kwemezwa
  • Inkunga yo gusesengura kunanirwa muri laboratoire
Saba Isesengura Ryatsinzwe
Inkunga ya tekiniki

Imibare yizewe hamwe nisesengura ryubuzima bwose
