Photodiode PR5020/21

Dark Current

MEASUREMENT SETUP

Dark currents of the C1-, C2- and C3-photodiode

are measured as a function of reverse voltage

and temperature. The substrate (A) is connec-

ted to ground, while a positive voltage is ap-

plied to Cx. The dark currents of Cx are meas-

ured at each pin separately.

OVER TEMPERATURE

Dark currents for photodiodes of different size

in PR5020 are shown at reverse voltages of 1 V

(blue) and 30 V (orange). In general, dark cur-

rents rise by approximately a factor 10 every

20 °C. Due to edge effects, bigger photodiodes

show a smaller leakage current per area.

AS A FUNCTION OF REVERSE VOLTAGE

The following diagram shows the dependency

of dark currents of the smaller C1/C3 (lower

curves) and the bigger C2 (upper curve) of

PR5020 on reverse voltage at different temper-

atures.
