1N4448WSQ-7-F Datasheet/PDF1N4448WSQ-7-F is a function of diodes - rectifiers - single, widely applied in many fields. This article predicts its application and then focuses on its working principle.
1. Application
1N4448WSQ-7-F is widely used in battery chargers and automotive applications, such as digital power supplies, LED lighting, battery chargers, etc. It also has wide use for both power rectification and signal clamping. Like other diodes, it becomes a low electrical resistance when top-emitting current, and a high resistance when bottom-emitting. Therefore, it can be used to protect the current control circuits in switching regulator and open loop voltage regulator, as well as other electronic components.
2. Working Principle
The 1N4448WSQ-7-F diode is composed of a semiconductor material, usually made of silicon, and two metal electrodes, the anode and the cathode. When the anode is connected to the positive pole and the cathode is connected to the negative pole of the power supply, a forward voltage is applied and current begins to flow from the anode to the cathode. This forward biased allows current to flow from anode to cathode.
In the reverse direction, no current passes through the diode and the voltage is not enough to allow current to flow. Therefore, the diode can be used for isolation between circuits and to protect other components from being damaged. This is the basic principle of the diode.
Conclusion
This article has introduced the application field and working principle of 1N4448WSQ-7-F. It is a kind of diodes - rectifiers - single, wide used in battery chargers and automotive applications. In addition, its principle is also clear, which is forward biased allows current flow from anode to cathode, the reverse direction, no current passes through the diode.
