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

Definition from Lucrarea nr.8 – Senzori şi sisteme se:
Curentul electric slab care traversează un dispozitiv fotoelectric în absenţa unui flux luminos incident, adică a fotonilor.

Example sentence(s):
  • Curentul de saturaţie Iinv, care corespunde unui flux luminos incident nul, se numeşte curent de întuneric (~ 1 μA). - Lucrarea nr.8 – Senzori şi sisteme se  
  • Parametrii specifici unei fotodiode sunt: -curentul de întuneric ILo , este curentul prin fotodiodă la iluminare nulă;... - Universitatea Tg, Jiu – Facultatea de  
  • Printr-un semiconductor supus unei diferenţe de potenţial U va trece un curent electric slab (de întuneric), care creşte, atunci când semiconductorul este iluminat, datorită fotoconducţiei. Intensitatea fotocurentului, diferită de cea a curentului de întuneric, depinde de temperatură, tensiunea electrică aplicată şi de durata iluminării. - UNIV."POLITEHNICA" DIN BUCUREŞTI
