Zener diodes are used in the over-voltage protection circuits in TV sets, and in series-type voltage-stabilizing circuits, the series-type voltage-stabilizing circuit is used in many occasions, and more stable power can be obtained by connecting in series.
Zener diodes are often represented by "ZD" plus a number in the circuit.
Five parameters of Zener diode:
1. Stable voltage
With the change of operating temperature and current, the Zener diode needs to be stabilized.
2. Working current
The voltage stabilizing diode changes according to the operating current. In general, the operating current is large, and the effect of voltage stabilization will be better.
3. Stable current
The Zener diode can stabilize the voltage with the current when it is working.
4. Dissipated power
In actual use, the Zener diode consumption is not allowed to exceed the standard.
