About This Product
With the Zener Diode Unit, students increase the reverse voltage step by step and watch the current stay small until breakdown, after which the voltage across the diode holds nearly constant. That behaviour is the basis of simple voltage regulators, so the unit links semiconductor physics to power supply practicals.
