The Peak Atlas ZEN50 is ideal for testing Zener diodes (including avalanche diodes), transient suppressors, LEDs and LED strings. It generates constant current pulses (selectable from 2 mA, 5 mA, 10 mA and 15 mA) at voltages from 0 V to 50 V. So even high voltage Zeners or high voltage LED strings can be tested.
Test currents are supplied in narrow pulses to ensure that the component under test remains at a constant temperature.
The voltage of the part is displayed on the screen together with the test current and also a measure of the component's slope resistance (also known as dynamic impedance).
