The Peak ZEN50 Atlas ZEN - Zener Diode Analyser tests zener diodes, avalanche diodes, VDRs, TVSs, LED strings and much more, up to a maximum voltage of 50V.
Measures breakdown voltage (0 to 50V) with a resolution as fine as 20mV
Measures slope resistance (up to 1kΩ at 15mA with a 1Ω resolution)
Supports most Zener diodes, avalanche diodes and reference diodes from 0 to 50V
Great for testing VDRs, TVSs and other types of voltage protection devices
Selectable test currents: 2, 5, 10 and 15mA
Tiny duty cycle of test current to minimise heating of your component even when testing at 50V and 15mA
Test voltages are below levels described in the Low Voltage Directive 2006/95/EC
Continuous measurement display (updated 3 times per second)
Measurement 'hold' function to hold displayed values even if component is removed
Fitted gold plated crocodile (alligator) clips
Very comprehensive printed user guide
Long battery life and regulated test conditions even when the battery voltage is as low as 1.0V
Powered by a single alkaline AAA battery (included)
As a simple bench checker, this is very useful. Both for manufacture and test/repair.
It is often difficult to know the conduction characteristics of zeners for various reasons.
Distributors selling product with the same part numbering from different sources and manufacturers tolerance are the most obvious. Then surface mount numbering is often uncertain.
Within a few seconds the important characteristics a clearly displayed.
