1N4681 BK

Diodes - Zener - Single

The 1N4681 BK Zener Diode is a single diode capable of providing voltage regulation for the vast majority of electronic appliances. It is commonly used for precision voltage regulation in portable and automotive electronics. This device is designed to operate in such a way to regulate a steady output voltage whether the load changes or not. It may also be used in a variety of applications, such as rectifying, clamping and voltage regulation.

The 1N4681 BK Zener Diode is a two-terminal semiconductor device that provides low-level current regulation. The device operates by using a reverse-biased P-N junction, which creates an electric field that amplifies and stabilizes the voltage applied to its cathode. The device is able to regulate a steady output voltage, regardless of the load changes or input amplitude variations. It is an effective and efficient device that can provide voltage regulation without the need of adjusting the input or output voltages.

The device typically includes two terminals, an anode and a cathode. The anode is the positive terminal and the cathode is the negative terminal. When the diode is biased in the forward direction, it allows current to flow from the anode to the cathode. However, when the diode is biased in the reverse direction, it creates a depletion region across the P-N junction, effectively preventing current to flow.

The device is usually designed to operate in the Zener breakdown mode, in which electrons are free to move from the anode to the cathode of the device. This creates an avalanche effect, which looks like a large spike in the output voltage when the current is increased beyond a certain level. This avalanche effect enables the device to regulate the output voltage to a predetermined level, regardless of the load changes or input amplitude variations.

In addition to regulating the output voltage, the device can also be used as a rectifier, clamping diode, or transient-suppression diode. As a rectifier, the device is able to block the current flow in one direction, while allowing it to flow in the opposite direction. As a clamping diode, the device is able to protect the system from excessive voltage by preventing the voltage from exceeding predetermined limits. Finally, as a transient-suppression diode, the device is able to protect the system from high-voltage transients that can cause damage to the electronic components.

The 1N4681 BK Zener Diode is a versatile device capable of providing low-level current regulation, rectification, clamping, and transient suppression. It is an effective and efficient device that is widely used in a variety of applications. It is well-suited for use in portable and automotive electronics and is capable of providing precision voltage regulation without the need of adjusting the input or output voltages.
