Me kwanen da Transistor Darlington?

Mushin Darlington Transistor shine da Dukki?

Tashar Mushin Darlington Transistor

Mushin Darlington transistor shine da wurare mai tsarki da ke amfani da biyu BJT (Bipolar Junction Transistors) don samun hanyoyi mai yawa, tana yi aiki a matsayin abu mai yawa.

Kwafin Mushin Darlington Transistor

Mushin Darlington Transistor ya fara da biyu PNP ko NPN transistors wanda suka kula. Tana cikin package na musamman da kuma terminal collector na duka biyu transistors.

Terminal Emitter na transistor na farko ya kula da terminal Base na transistor na biyu. Saboda haka, supply base tana bayarwa ne transistor na farko, kuma current output tana gudanar da transistor na biyu. Saboda haka, tana da terminal base, emitter, da kuma collector na musamman kamar yadda aka nuna a wannan tasweer.

Samun Hanyoyi

Hanyoyin current na mushin Darlington pair yana da muhimmanci da hanyoyin standard transistors, tana taimakawa wajen aiki da amfani da amplification mai yawa.

PNP da NPN Darlington Transistor

Idan mushin Darlington pair ta fara da biyu PNP transistors, tana da PNP Darlington Transistor. Kuma idan ta fara da biyu NPN transistors, tana da NPN Darlington Transistor. Tasweer na diagram connection na NPN da PNP Darlington Transistor ya nuna a wannan tasweer.

Don duk biyu transistors, terminal Collector tana musamman. A transistor na PNP, base current tana bayarwa ne terminal emitter na transistor na biyu. Kuma a transistor na NPN, emitter current tana bayarwa ne terminal base na transistor na biyu.

Mushin Darlington transistors suna bukata kyau da biyu transistors masu sarrafa saboda suke da terminal collector na musamman.

Mushin Darlington Transistor Switch

Idan muke so in karfi da kuma kawo load game da microcontroller. Don haka, muna iya amfani da transistor na musamman a matsayin switch, kuma baya muna iya amfani da mushin Darlington transistor. Diagram circuit na wannan configuration ya nuna a wannan tasweer.

Fadada Mushin Darlington Transistor

Mushin Darlington transistor (i.e. Darlington pair) tana da fadada da dama da normal transistor. Su kan fadada a wannan jerin:

• Fadada mafi muhimmanci na mushin Darlington transistor shine samun hanyoyi mai yawa. Saboda haka, small amount of base current zai iya karfin transistor.

• Yana ba da high input impedance wanda tana haɗa da equal decrease in output impedance.

• Tana cikin package na musamman. Saboda haka, tana da kyau a yi configuration a matsayin circuit board ko PCB daga ma amfani da biyu transistors masu sarrafa.

Muhimmiyar Mushin Darlington Transistor

Muhimmiyoyin mushin Darlington transistor (i.e. Darlington pair) su kan a wannan jerin:

• Yana da slow switching speed.

• Base-emitter voltage tana da kusa da normal transistor.

• Saboda high saturation voltage, a wannan application, tana da high power dissipation.

• Bandwidth tana da kusa.

• Mushin Darlington transistor tana ba da phase shift a certain frequency a negative feedback circuit.
