About This Product
Students raise the reverse voltage until the Zener breaks down and note how the voltage then stays almost fixed as the current rises, which is the basis of voltage regulation. The socket lets them swap diodes and compare breakdown voltages in electronics and physics practicals. The Zener Diode Apparatus (Socket Type) can be supplied on export terms to Belgium, Uganda, United Kingdom, Bulgaria, Sri Lanka and Costa Rica.
Frequently Asked Questions
Can different Zener diodes be tested?
Yes. The diode fits in a socket, so Zener diodes can be interchanged.
