DB2141300L

Diodes - Rectifiers - Single

The DB2141300L is a diode, specifically a single rectifier diode. It is used to allow electrical current to flow through a circuit in one direction while blocking current in the opposite direction. This creates a type of electrical “one-way valve” that is essential in most electronic and circuit applications. The DB2141300Lin particular is a robust part capable of handling high voltage and current and features an impressive surge current rating of 108A.

Application Field

The application field of the DB2141300L is broad and can be found in a variety of different electronics and circuitry. Some of the most common applications include motor controls, power factor correction, HID lighting, energy conversion and power supply applications such as servers and PCs.

The main advantages of using this particular diode are its robust construction and ability to withstand high currents. This means it is particularly suited for high-power applications such as motor controllers. It can also be used in HID lighting as it is also able to support high peak currents.

The high surge current rating of the DB2141300L makes it an ideal choice for use in PFC converters, wherein it can support large start-up currents. Its long reverse recovery time and low capacitance also make it an ideal choice for use in high-frequency switching applications.

Working Principle

Diodes, including the DB2141300L, work based on two principles: forward bias and reverse bias. For a diode to conduct current, a voltage must be applied to the two ends of the device. This is known as forward bias. If the applied voltage is greater than a certain value, known as the forward voltage, then the diode will turn on, allowing current to flow through it. The current flow is then limited by the resistance of the diode.

When the voltage is reversed, it is said to be in reverse bias. The diode will be off and no current is allowed to flow. This makes diodes very useful in protecting circuits from reverse current, as reverse bias will effectively short-circuit the diode and other components in the circuit. The DB2141300L is constructed such that it can also support high reverse bias, making it suitable for use in high voltage applications.
