Zener Diode Schaltbild. Diode allows current flow in one direction only left to right. Allows current flow in one direction but also can flow in the reverse direction when above breakdown voltage.
Determine the current through the series resistor. Schottky diode is a diode with low voltage drop. We operate a zener diode in reverse biased conditions and this diode does not get damaged even when the voltage across this exceeds the reverse breakdown voltage.
15 ma x 5 1 volts 76 5 mw.
Zener diode is connected parallel to the load to make it reverse bias and once the zener diode exceeds knee voltage the voltage across the load will become constant. The zener diode maintains a stable output voltage irrespective of the input voltage provided the maximum zener current is not exceeded. Check the zener diode power dissipation. The interesting part of the transformer is this.
