Kodi pnp-transistor?

Transistors - ndi zipangizo theka-wochititsa, imene mfundo zosachepera zitatu. Mu zochitika zina, iwo amatha kukulitsa luso kupanga Phokoso kapena kuwatembenuza mbendera. Pali zambiri yosiyanasiyana mwa zipangizozi, ndi mwa iwo - pnp-transistor.

M'kagulu transistors pa nkhani michenga yopangira zida zamagetsi. Iwo anapanga pakachitsulo, germanium, etc.

Ngati transistor wa mbali zitatu awiri tsa-mtundu madutsidwe, umatchedwa "transistor ndi madutsidwe mwachindunji", kapena "kutengerapo transistor pnp". An zida zimene zigawo ziwiri elekitironi madutsidwe, zimakambidwa ngati ndi transistor ndi kuchititsa n'zosiyana kapena kusintha npn. Ntchito transistors onse ali ofanana, koma kusiyana lili okha polarity lapansi.

Kodi applicable pnp-transistor?

Malinga ndi zimene mtundu wa makhalidwe m'mayiko maulendo, akhoza kumwedwa ambiri. Monga tanenera kale, transistor ntchito m'badwo, kusinthika ndi amveke wa chizindikiro magetsi. Chifukwa chakuti athandizira voteji kapena masiku ano anasintha, ukutsogolera ikuchitika a dera athandizira. kusintha Small mu magawo athandizira kuyambitsa kusintha kwambiri panopa linanena bungwe ndi voteji. Chotero amveke katundu ntchito luso analogi (wailesi, analogi TV, mauthenga ndi zina zotero. D.).

Mu nthawi yathu, amanena kuti analogi njira ochititsa kuti pnp-transistor. Ndipo apa ndi gawo ina yofunika kwambiri - digito zamakono - pafupifupi anakana izo ndi amagwiritsa kumunda kokha. Maganizo pnp-transistor anaonekera munda kale kwambiri, chifukwa mu parlance wamba anangomutchula kuti transistor a.

Magwiridwe a Ntchito ndi magawo a transistors ndi

Transistors constructively anapanga pulasitiki ndi zitsulo m'makola mwawo. Poganizira zolinga zosiyanasiyana transistors, zipangizozi amasankhidwa molingana ndi magawo ena. Mwachitsanzo, ngati transistor amveke wa mafurikwense kwambiri, iwo ayenera kukhala mkulu pafupipafupi chizindikiro amveke. Ndipo ngati transistor pnp ntchito yang'anira panopa, tiyenera mkulu zikugwira ntchito wokhometsa panopa.

Lina lili makhalidwe waukulu transistor ndi:

• Ik - ikugwira ntchito (pazipita) wokhometsa panopa;
• h21e - phindu;
• Fgr - pazipita pafupipafupi amveke;
• PK - wokhometsa madyaidya ndikuledzera mphamvu.

phototransistors

Phototransistor - chipangizo tcheru ndi kamwazi kuwala, zomwe irradiates izo. The losindikizidwa nyumba bokosi la chotero transistor mwachita Mwachitsanzo, zopangidwa pulasitiki chimaonekera kapena galasi. Cheza kudzera Lifikira m'munsi mwa zone phototransistor. Ngati maziko ali irradiated, ndiye mlandu zonyamulira amayambira. Phototransistor kutsegula pamene mlandu zonyamulira kusamukira ku wokhometsa yakumapeto, ndi zambiri lidzadzala m'munsi, wokhometsa panopa adzakhala yokulirapo.

Popanda transistors simungathe kulingalira zamagetsi zamakono. Pafupifupi palibe chipangizo kwambiri simungakhoze kuchita popanda iwo. M'zaka za ntchito ndi chitukuko cha transistors zasintha kwambiri, koma mfundo ya ntchito n'chimodzimodzi.
