I kēia pae i ka pae noi ʻoihana, ʻo ka mea kūʻai mua i ka mea hoʻohana uila uila mea hoʻopili waiwai. A e like me ka hoʻohana nui ʻana o ka MOSFET grasp, ʻo ka noi no ka MOSFET i ka lua o ka motherboard computer, NB, computer power adapter, LCD display a me nā waiwai ʻē aʻe. Me ka hoʻomohala ʻana o nā kūlana ʻāina maʻamau, nā motherboards kamepiula, nā mea hoʻololi mana ʻoihana kamepiula, nā nānā LCD ma nā koi oMOSFET pono e hele ma mua o ke kūlana o nā mea hoʻopili uila uila.

Aia ma lalo kaMOS kūpono ʻole ʻeono kumu nui.

1. Landslide invalid (operating voltage invalid), i 'ike pinepine 'ia e like me ka leakage ma waena o ke kumu o ka BVdss hana voltage ma mua o ka helu o ka MOSFET, a ma waho aku e hana i kekahi hana e alakai i ka MOSFET invalid.

2. He kūpono ʻole ka SOA (ʻAʻole kūpono ke kahe mana), ma luna o ka MOSFET wahi hana palekana i hana ʻia e ka mea kūpono ʻole, i māhele ʻia i Id ma luna o nā kikoʻī o ka hāmeʻa a ʻaʻole i kūpono a ʻoi aku ka nui o kāna Id, kiʻekiʻe a me nā waimaka o ka hāmeʻa i ka hōʻiliʻili wela no ka wā lōʻihi i hana ʻia e ka invalid.

3. Pono ʻole ke kino diode. Ma ke alahaka, ʻo LLC a me nā mea ʻē aʻe i ka diode kino e hoʻokō i ka hoʻomau ʻana o ka topology pūnaewele, no ka mea, pili ka diode kino i ka invalidation.

4. ʻAʻole kūpono ke kani kani. I ka noi moʻo o ka loulou, ka puka a me ka mana lako kaapuni parasitic parameter e alakaʻi i ka fluctuations ma muli o ka invalidation.

5. ʻAʻole kūpono ka induction electrostatic. I ka hoʻoilo a me ka hāʻule, no ke kino a me nā mīkini a me nā mea hana ma muli o ka induction electrostatic i hoʻokumu ʻia e ka hāmeʻa.

6. ʻAʻohe mana o ka puka makani. No ka mea, ʻaʻole i kūpono ka ʻīpuka, a ʻaʻole kūpono ka pae o ka oxygen i ka puka.
