The Elektor Zener Diode Tester is essentially a constant-current source that can be switched in steps from 1 to 50 mA. It can be used to test Z-diodes up to a maximum of 54 V. Thanks to a 60-V step-up converter, the device can be powered by the usual 5 to 12 V. The principle of this tester is straightforward. A Z-diode or other DUT (device under test, such as an LED) is biased by an adjustable current source. The voltage across the DUT can be measured with a multimeter. The voltage of most (small) Z-diodes is specified at a current of 5 mA. Depending on the application, the voltage at other currents can also be of interest. That is why six current settings are available: 1, 2, 5, 10, 20, and 50 mA. LEDs are often specified at a current of 20 mA. What can be tested is: Whether a Z-diode is defective (short circuit or high impedance). Whether a Z-diode exhibits the correct Z-voltage. How a Z-voltage changes with different currents. What exact voltage is present at an integrated voltage reference. Whether LEDs in a series chain differ in brightness (hence the 20 mA current). What the current gain is for different base currents in (power) transistors. The kit contains all parts listed in the bill of materials including PCB and enclosure.
