Transistor pourua - te wae taketake mō te faananea- raa tohu hiko

I roto i te whanaketanga o rua kāinga me te ao hiko, me te hikohiko takaro he tūranga matua whakaaro Semiconductor pērā pērā i transistor pourua.

transistor pourua - he pūrere, he i roto i tona hanganga o rua huinga PN tūhonohono hāngai, kei runga i ngā rauemi Semiconductor. E toru terminals tenei momo o te transistor. Faananea- raa āhuatanga, e kua he transistor pourua, faataa i te pūtake o te matauranga o taonga, ka mauriora Semiconductor platelets utu (werohia puritia me ngā tukanga tangohanga, aua), kia rite ki te pai kia rite ki te ture o te autōhiko.

I teie mahana i reira e rua ngā momo matua o transistors pourua, e kua tohaina kia rite ki te tikanga i roto i nei i reira ko te whakarerekētanga o ngā rohe o te momo rerekē kawe ia o te Semiconductor whakamahia i roto i te tauira: te momo npn me PnP. e kore e taea te kitea nga painga o te momo kotahi i runga i te tahi atu no te te rerekētanga i waenganui i enei momo o transistors he anake te mea e hono te wehenga tawhiti o te pūtake mana waho ki te tahi i te tahi pūrere kāpeka ranei.

Transistor - pūrere pourua arā, o toru huānga matua: he tango, turanga me te kaituku. hono takitaha o nga mea timatanga ko, rite ki te tikanga, kia kotahi kāpeka.

Kei te maha transistors pourua whakarōpūtia e te mana toreretanga, mawehe atu i te kaikohi. Na roto i tenei tawhā e wehea whakaaro ki transistors mana-iti (e pā ana ki 0.3 W), reo (0.3 ki te hawhe Watt) me te tiketike (1.5 Watts). Tētahi atu parau tumu o te whakarōpū o transistors - o te mahi ngā auau. I roto i taua pūrere te parau tumu wehenga emit whakaaro iti auau (e rima MHz), auau reo (5 MHz ki 35 MHz), HF (i 35 MHz ki 350 MHz) me te ngaruiti (i runga i 350MHz) transistors.

whiwhi ia transistor pourua tohu i runga i ngā paerewa ā-motu e hāngai ana. Ka rite ki te tikanga, i hanga te ti'araa e ake o te ono e whitu ranei pūāhua (tau reta ranei). Me tohu te momo o rauemi, momo o te pūrere iho, me nga āhuatanga auau o te pūrere mana te tohu. Ano, Ka taea e tapanga whakatau i te momo, me te tau rangatū o te whanaketanga o te hua. Ko te kupu, ko te ti'araa o te transistor - he uruwhenua pūrere, e heheu te āhuatanga matua katoa o te pūrere.

E wha aratau taketake o te mahi o te transistor pourua:

• he aratau kaha i roto i i whakatuwheratia te irava te ka katia i te kaituku ki te irava tango;
• tapahia-atu, i roto i nei haere e rua te whakawhiti (me te kaituku me te kaikohi) e katia me kahore nāianei e i roto i te aronga whakamua;
• waiwai - te aratau cutoff ritenga i ai whakawhitinga ki te kaikohi tuwhera, me te kaituku;
• koaro (aratau Taupokia) - wāhanga i te wahanga o te huinga tango te ka ngā te kaituku i roto i te huarahi i te ritenga (kore whakawhiti i te "tika" nāianei).

Tei runga i nei o nga electrodes (terminals) o te transistor riro noa ki nga hūkere o amplification me te wāhi me te putanga o nāianei, i reira e toru ngā momo taketake o ngā pūrere ngā i roto i te ara iahiko: he transistor pourua ki noa kaituku, kaikohi turanga ranei. Tei runga i te aha te momo o whakawhiti whakaaro whakamahia i roto i te wā ngā, ka taea e koe te whakamahi i te painga ngā o te transistor.

I roto i te mutunga, i kite mātou i teie mahana e whānui te transistors pourua whakamahia i roto i te hikohiko me te hikohiko tairitenga. Ēnei whakaaro e whakamahia i roto i te whānuitanga o ngā wāhanga amplification kahore ratou e kore e waiho e taea ki te hanga i tētahi tīwerawera whakahaere - he pūrere whakaaetia e te ki te waihanga i tētahi whakawhitinga i tairitenga ki circuitry mamati. Na reira, e taea te whakaaro te transistor pourua tetahi o te taketake tino o ngā pūrere Semiconductor, whakatakotoria whanaketanga te turanga o te hikohiko hou.
