Specifications of 12V 1W Zener Diodes

The specifications of a 12V 1W Zener diode include the following: 1. Breakdown voltage: The breakdown voltage of a 12V 1W Zener diode is 12 volts. This means that the diode will start conducting in the reverse-biased condition when the voltage across its terminals reaches 12 volts. 2. Power rating: The power rating of a 12V 1W Zener diode is 1 watt. This indicates the maximum power the diode can dissipate without causing damage to itself. 3. Maximum current: The maximum current that can flow through a 12V 1W Zener diode is typically around 100mA. It is essential to ensure that the current flowing through the diode does not exceed this value to prevent damage. 4. Maximum voltage: The maximum voltage that can be applied across a 12V 1W Zener diode is 18 volts. Applying a voltage higher than this value can cause the diode to fail. 5. Reverse leakage current: The reverse leakage current of a 12V 1W Zener diode is typically very low, usually in the microampere range. This ensures that the diode maintains a stable voltage across its terminals even when the current is minimal.
