What are the parameters of Zener diodes?

The parameters of the zener diode are: 1. Rated voltage, which refers to the voltage that the diode can stably output under specified working conditions; 2. Operating current range, which needs to work within a certain operating current range; 3. Maximum Power refers to the maximum power that the diode can work stably under the specified operating temperature; 4. Temperature coefficient, which describes the trend of its rated voltage changing with temperature; 5. Maximum reverse current, the voltage of the Zener diode under reverse voltage Maximum allowable current; 6. Intermittent current, the overcurrent peak value that the Zener diode can withstand instantaneously, is usually used to describe the transient protection capability.

The parameters of the Zener diode (Zener diode) mainly include the following aspects:

1. Rated voltage (Nominal Voltage): The rated voltage of the Zener diode refers to the Under specified operating conditions, the diode can stabilize the output voltage. It is usually expressed in units of volts (V).

2. Operating Current Range: The Zener diode needs to work within a certain operating current range to maintain a stable voltage output. Beyond this range, the diode may not function properly. Operating current range is usually expressed in milliamps (mA).

3. Maximum Power Dissipation: The maximum power of the Zener diode refers to the maximum power that the diode can work stably at the specified operating temperature. Exceeding maximum power may cause diode damage. Maximum power is usually expressed in watts (W).

4. Temperature Coefficient: The temperature coefficient of a Zener diode describes the tendency of its rated voltage to change with temperature. It can be positive, negative or zero. A positive temperature coefficient means that the rated voltage increases with temperature, a negative temperature coefficient does the opposite. A zero temperature coefficient means that the rated voltage basically does not change with temperature within a certain temperature range.

5. Maximum Reverse Current: The maximum allowable current of the Zener diode under reverse voltage. When this current is exceeded, the diode may be damaged. Maximum reverse current is usually expressed in milliamperes (mA).

6. Intermittent current (Surge Current): The overcurrent peak value that the Zener diode can withstand instantaneously. It is usually used to describe the transient protection capability. Intermittent current is usually expressed in units of milliamperes (mA).

These parameters can be found and confirmed based on the specific Zener diode model and manufacturer. When using Zener diodes, appropriate parameters need to be selected based on application requirements to ensure proper operation and reliability.
