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

corrent de foscor

Definition from Termcat:
Corrent que flueix pels terminals d'un dispositiu fotosensible en absència d'il·luminació.

Example sentence(s):
  • 2.6. Resposta espectral SR. 2.7. Corrent de foscor. Efectes del material fotovoltaic. 2.8. Superposició. - UPC  
  • [IMPORTANT: SEE NOTE] Funcionament: Sense llum: com que el fotodiode està polaritzat en inversa, no hi circula corrent a través seu ( només la corrent de foscor, es considera zero). Per tant la tensió en el potenciòmetre serà pràcticament zero. - Exercici telecos  
  • 3. Receptors òptics Detecció de llum en unions p-n. Díodes PIN i APD. Circuit equivalent, amplificador transimpedancia. Responsivitat, corrent de foscor. Soroll tèrmic, soroll shot, factor allau. Conseqüències de la conversió potència òptica a corrent elèctric: soroll de batut (beat noise) SASE i ASE-ASE. Ample de banda en dispositius actuals. Paràmetres de modelatge: densitat espectral de soroll, M, k. - UAB
