Description

This silicium semiconductor diode named Z diode is used in reverse-biasing. It works like a standard diode in conducting direction but becomes low resistance itself when the mentioned working voltage (the Zener voltage) is reached. From this voltage on the current increases abruptly. This effect named Zener effect is caused by an electrical field that frees electrons from there crystal bindings.

The very large conductance of the diode after this effect makes rationing of electricity neccessary or the Z diode will be destroyed. The maximum current to flow through the Z diode can be drawn by a series resitant RV (Drawing 1) which can be calculated as shown on the left side.

Formula 2 shows the calculation of the minimum current Iz min of the diode.

Formula 3 shows the calculation of the maximum current Iz max of the diode.

Delivery time

Deliveries within Germany take 2-3 days beginning after receipt of payment, for deliveries to invoice beginning with the shipment, for deliveries to cash on delivery beginning with receipt of order. Payments and incoming orders beyond our business hours let the delivery time begin with the next workday. For deliveries to other EU countries the delivery time may be extended up to 3 weeks. The delivery time is subject to the proper delivery of the logistics company, as far as delivery delays are not caused by us. The validity of the above delivery times requires the availability of the ordered goods from stock at the time the delivery time is beginning.
