He aha te mea he PnP-transistor?

Transistors - he whakaaro āhua-kaiwhakahaere, i roto i nei kahore iti iho i te toru whakatau. I roto i etahi āhuatanga, ka taea e ratou te whakarei ake i te āheinga ki te whakaputa wiri ranei tahuri te tohu. He he rota o whakaaro rerekē o enei whakaaro, ka i roto ia ratou - PnP-transistor.

Whakarōpū transistors i runga i te rauemi Semiconductor. E hanga ana ratou o silicon, germanium, me ētahi atu

Ki te whai te transistor o te wāhi e toru e rua kawe ia p-momo, huaina reira ko "transistor ki te kawe ia tika", ranei "PnP transistor whakawhiti". He taputapu i roto i nei i irahiko rua rohe kawe ia, tuku ki rite te transistor ki te tataki whakamuri whakawhitinga npn ranei. Ko te taua mahi transistors e rua, engari e takoto te rerekētanga anake i roto i te wehenga tawhiti.

Hea e hāngai ana PnP-transistor?

I runga anō i te aha te huru o ngā āhuatanga i roto i te whenua te tauwhiro, taea te whakamahi i te reira no te mau opuaraa e rave rahi. Ka rite ki kua whakahuatia, kua whakamahia te transistor mo te whakatupuranga, huringa me te amplification o tohu hiko. Nā ki te meka i puta ke te ngaohiko tāuru nāianei ranei te, kawea mana o nāianei i roto i o te ara iahiko tāuru. huringa iti i roto i te tawhā tāuru arahi ki te huringa ara nui i roto i te nāianei putanga me te ngaohiko. whakamahia rawa amplification taua i roto i te hangarau tairitenga (irirangi, TV tairitenga, kōrero, me te pera i runga i. D.).

I roto i to tatou wa, kua tono reira ki technique tairitenga pourua PnP-transistor. Na konei ko tetahi rāngai rawa nui - hangarau mamati - tata kihai reira me whakamahi mara anake. BAD PnP-transistor puta mara nui mua, no te mea te reira i roto i ngā mātapono noa tuku ki noa rite te transistor.

Mahinga me ngā tawhā o te transistors

Transistors āta hanga i roto i te kirihou me te whakarewa nohoanga. Whakaaro i te mau opuaraa rerekē o transistors, kua tīpakohia enei whakaaro rite ki etahi tawhā. Hei tauira, ki te te transistor mo amplification o iarere tiketike, me whai i te reira i te tohu amplification auau tiketike. A ki te mea te transistor PnP whakamahia i roto i te regulator nāianei, kia whai i te reira i tetahi o nāianei tiketike whakahaere.

Tohutoro kei nga āhuatanga matua o te transistor:

• Ik - whakahaere (mōrahi) kaikohi nāianei;
• h21e - taonga;
• FGR - mōrahi amplification auautanga;
• PK - kaikohi toreretanga mana.

phototransistors

Phototransistor - he pūrere tairongo ki te rere marama, e irradiates reira. Ko te pouaka whare hiri o te transistor taua mahi, hei tauira, i hanga o te kirihou mārama karaihe ranei. Radiation i roto i reira tomo te turanga o te rohe phototransistor. Ki te irradiated te turanga e, na kua hangaia te kawe tiaki. Phototransistor whakatuwhera ka neke kawe tiaki ki te huinga tango, me te ake ka taupokina turanga, ka kia nui te nāianei tango.

Te kore transistors kore e taea whakaaro te hikohiko hou. Tata kore e taea te mea i kore pūrere nui, kahore a ratou. I roto i nga tau o te tono me te whanaketanga o transistors kua tino puta ke, engari ko te taua te parau tumu o ratou mahi.
