Science - Physics
Additional field(s): Electronics / Elect Eng
English term or phrase: dark current
Definition from Tyco Electronics Corporation:
The thermally induced current that exists in a photodiode in the absence of incident optical power.

Example sentence(s):
  • This voltage may be as low as 10 mV or as high as 50 V and the dark currents may vary from pA to μA depending upon the junction area and the process used. Dark current is always specified at a particular value of reverse applied voltage. optoelectronics.perkinelmer.com
  • The photodiode noise in is the sum of the thermal noise (or Johnson noise) ij of a resistor which approximates the shunt resistance and the shot noise isD and isL resulting from the dark current and the photocurrent. Hamamatsu Corporation
  • Dark current is dependent on temperature. While dark current may initially be low, it will increase as the device temperature increases. tpub.com

tumsas strāva


Definition from Wikipedia:
Tumsas strāva ir strāva anodķēdē, kas plūst bez gaismas iedarbības un parasti nepārsniedz 10-9 līdz 10-10 A.

Example sentence(s):
  • Pielietojot tradicionālo vidējās strāvas mērīšanas metodi, lomu nespēlē divi pēdējie parametri R un β: ηFED = (Ia – Iat) / e* M * = ηk * γp * (1 – P0), (5 – 2) kur Ia – anoda strāva, ja uz fotokatodu krīt vidējā fotonu plūsma , Iat – anoda tumsas strāva, e – elektrona lādiņš, M – daudzkāršotāja pavairošanas koeficients. - "Fotonu skaitīšana un tās lietojums"
