Ndechipi pnp-transistor?

Transistors - a Semi-kondakita mano, umo mhedziso isina asingasviki matatu. Mumamwe mamiriro ezvinhu, vanogona kuwedzera kukwanisa kuti vaunze vibrations kana kutendeutsa chiratidzo. Pane yakawanda yakasiyana mazano mano izvi, uye pakati pavo - pnp-transistor.

Patsanura transistors ari semiconductor zvinhu. Ivo yakagadzirwa nesilicon, germanium, etc.

Kana transistor nhatu nzvimbo mbiri S.-mhando conductivity nayo, anonzi "transistor ne zvakananga conductivity", kana "kutapurirana transistor pnp". An midziyo umo kumatunhu maviri Erekitironi conductivity, kunzi transistor ane neizvi anoitisa kana iitike npn. Anoshanda zvose transistors ndiwo chete, asi musiyano nhema chete polarity.

Apo zvinoshanda pnp-transistor?

Zvichienderana worudzii unhu dzaifanoiswa nyika, rinogona kushandiswa zvinangwa zvakawanda. Sezvambotaurwa, kune transistor rinoshandiswa Chizvarwa, kuchinja uye amplification kuti zviratidzo zvemagetsi. Nokuti kuti mazano voltage kana kuitika nechakatsinhiwa, kuzvidzora ano achaendeswa kubva mazano redunhu. kuchinja Small mune mazano parameters kukonzera kuchinja kukuru mune goho ano uye voltage. pfuma amplification kwakadaro rinoshandiswa analoginen technology (redhiyo, analoginen TV, kukurukurirana uye zvichingodaro. D.).

Munguva yedu, izvozvo rinoshandiswa analoginen unyanzvi nedambudziko pnp-transistor. Uye pano mumwe kwemauto chinokosha - digitaalinen Michina - akapotsa akaramba izvozvo uye anoshandisa chete munda. Nedambudziko pnp-transistor akazviratidza ipapa munda, nokuti zvakafanana parlance rinotaurwa kungonotandara transistor.

Performance uye parameters of transistors

Transistors zvinovaka akaita mupurasitiki simbi zviruva. Tichitarisa siyana zvinangwa transistors, mano aya vanosarudzwa maererano zvimwe parameters. Somuenzaniso, kana munhu transistor kuti amplification dzakakwirira frequencies, tinofanira kuva mukuru Frequency chiratidzo amplification. Uye kana pnp transistor rinoshandiswa ano regulator, chinofanira kuva matunhu kushanda nomuteresi ano.

phototransistors

Phototransistor - zano kunzwisisa chiedza zvinoyerera iyo irradiates izvozvo. The rakanamwa pekugara bhokisi rimwe transistor chakadai chakaitwa Somuenzaniso, akagadzirwa läpinäkyvä epurasitiki kana rinoonekera. Radiation kuburikidza inopinda mujinga phototransistor wongoramba. Kana mujinga iri irradiated, ipapo nokubatira vatakuri kunotangira. Phototransistor kuvhura kana mutariri vatakuri kufamba munzvimbo nomuteresi Junction, uye zvakawanda ichazadzwa chawo, kuti nomuteresi ano achava chakazvibata.

Pasina transistors haagoni kufungidzira Electronics ano. Zvinenge hapana Mudziyo chakakomba haagoni kuita pasina pavo. Mumakore ose kushanda uye kugadzira transistors vakachinja zvikuru, asi nheyo kushanda kwavo chete.
