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

arus gelap


Definition from FISIKA FMIPA UI:
Arus gelap adalah arus mundur fotodioda pada saat tak ada cahaya. Arus gelap ini bergantung pada suhu, biasanya arus gelap ini cukup besar dibandingkan dengan dioda hubungan (arus mundur) dalam orde nA atau μA tergantung pada luas permukaan devais.

Example sentence(s):
  • Arus "gelap" (dark current, lihat gambar) berhubungan dengan arus saturasi mundur, karena pembentukan carrier minoritas secara termal. Jika cahaya dijatuhkan pada permukaan, terbentuk pasangan carrier, yang kemudian akan berdifusi ke junction dan menyeberangi junction sehingga menimbulkan arus. - Universitas Gunadarma  
  • Kurva citra gelap terbentuk dari hubungan antara waktu integrasi (s) sebagai sumbu absis dan count rata-rata (ADU) sebagai sumbu ordinat. Setelah itu dilakukan fitting garis lurus untuk memperoleh harga gradien (m) dan konstanta(c). Kurva ini dapat digunakan untuk menentukan harga laju arus gelap terhadap waktu dan harga bias level. - FPMIPA Universitas Pendidikan Indonesia  
  • Perubahan intensitas yang diterima sensor akibat dari perubahan indek bias pada medium kontrol akan mempengaruhi besarnya tegangan keluaran sensor. Arus gelap pada phototransistor sebesar 90 µA. - Berkala Fisika-Vol. 5, No. 1, Jan 2002
