Diodes, when used in electrical and electronic systems, are actions which allow current in only one direction and block current in the opposite direction. There are several types of diodes, such as rectifier diodes, zener diodes and Schottky diodes. Zener diodes are special types of diodes which are designed to operate in reverse bias, allowing them to conduct current in the reverse direction. Zener diodes have several applications, one of which is the application of JANTX1N4987DUS. This type of diode is a single-zener diode, with a maximum reverse voltage of 8.2V and a peak pulse power of 1W.
The application field of the JANTX1N4987DUS diode is that it is used to provide a stable voltage in applications such as power supplies or for voltage regulation for circuits. It is also used for the protection of other components from high voltage spikes. Additionally, the diode can be used to protect microcontrollers, circuits, and other electronic devices from electrostatic discharge (ESD).
The working principle of the JANTX1N4987DUS diode is based on the ability of a diode to conduct current in the reverse direction. When the diode is biased in the reverse direction, it will allow a certain amount of current to flow in. This current is regulated by the breakdown voltage of the diode, which is the voltage at which the diode will start to conduct. In the case of the JANTX1N4987DUS diode, the breakdown voltage is 8.2V. The current through the diode is proportional to the applied voltage, with the diode regulating the voltage. This regulation is what allows the diode to be used in power supplies and voltage regulation applications.
The reverse current flow of the JANTX1N4987DUS diode is also limited by its peak power and pulse peak power ratings. The maximum reverse current of the diode is limited by its peak power rating, which is 1W. This rating indicates the maximum amount of power the diode can dissipate without being damaged. The pulse peak power rating is a measure of the maximum amount of power the diode can handle in short high-voltage bursts. This rating is designed to protect the diode from voltage spikes that may exceed its power rating.
In summary, the JANTX1N4987DUS is a single-zener diode with a reverse voltage rating of 8.2V and a peak power rating of 1W. It is used in applications such as power supplies and voltage regulation, as well as protection against ESD and high-voltage spikes. The diode works by conducting current in the reverse direction, with the voltage regulation provided by the breakdown voltage of the diode. Its peak power and pulse peak power ratings limit the amount of current that can flow through the diode.
