Application Field
This type of diode is capable of a wide range of applications from rectification, protection, filtering, clamping to wave shaping. Its typical applications includes:
- Power Supply: 1N4002G BK is suitable for powering up low voltage circuits, such as for computers, electronics and automation equipment.
- Telecommunication: It is used for modems and base stations.
- Automotive: For vehicle electronics, such as headlights and interior lighting, pulse-width modulation, power windows and seat control.
Working Principle
This type of diode consists of two layers: P and N type. When a voltage is applied, current will flow through the diode, and a voltage drop occurs in the diode. The voltage drop depends on the voltage applied and the type of diode material.
The 1N4002G BK diode provides non-linear current-voltage characteristics, meaning that at a given voltage, the current can increase or decrease depending on the voltage. This property is known as rectification and is used for various applications such as wave-shaping, clamping and protection.
The working principle of the 1N4002G BK diode is based on the principle of “ PN-junction”,wherein, when the PN-junction is formed, an electric field is created on either side of the junction. This field prevents electrons from passing through, which results in rectification. The main function of the diode is to ensure that current only flows in one direction in order to provide a steady DC source.
Conclusion
This type of diode, 1N4002G BK, is capable of a wide range of applications such as rectification, protection, filtering, clamping and wave-shaping. It provides non-linear current-voltage characteristics, which enables it to provide a steady DC source. This type of diode is widely used in countless everyday application, from powering up low voltage circuits to vehicle electronics.
