Zener Diodes


Please peruse Circuit Specialists' selection of inexpensive Zener diodes which we carry in half, one, and five watt varieties in a wide range of voltages. These diodes differ from standard diodes in that they allow current to flow in the forward direction but also allow current to flow in the reverse direction when the voltage is above a certain value (i.e. breakdown voltage). Save even more when you buy in bulk.
