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

Example sentence(s):
  • 最近の車はスマートキー、ナビ、セキュリティ、エンスタ等、電流を必要とする電装品が多くあり、暗電流が多くなると、バッテリーの放電が早まってエンジンが始動できなくなり、バッテリーが上がってしまいます。 - 暗電流の正確な計測方法  
  • 自動車の場合は、時計、電装品のバックアップ、セキュリティなど、キーをOFFにしても電気が流れていることを「暗電流」といいます。 この暗電流は、車の装備品や車種ごとに違いますが、おおむね数mA~50mA位が標準的に流れている値です。 - http://minkara.carview.co.jp/userid/3022
