The 1N4681 is an axial-leaded, single, Zener diode. It is a PN-junction semiconductor device that exhibits a reverse breakdown voltage with a fairly sharp negative resistance region.The 1N4681 is a unique type of diode specifically designed to provide a precise voltage control in multiple applications. It has a high-level operating temperature range, making it suitable for a wide variety of operating environments.The 1N4681 Zener diode has a wide range of common applications that include voltage regulation, voltage clamping, and overvoltage protection. Thanks to its precise breakdown voltage, it can provide precise voltage regulation, which makes it ideal for use in analog circuitry and digital electronics.The 1N4681 Zener diode is capable of controlling voltage through two methods: Zener breakdown and avalanche breakdown. Zener breakdown occurs when a reverse bias is applied to a PN junction diode. This produces a breakdown voltage at which the electric current reaches a limiting value, providing a precise reference voltage. Avalanche breakdown is the result of an excessive reverse bias level applied to a diode. This produces a short-duration, high electric current to ensure an immediate clamping of excessive voltage.In addition to voltage regulation, the 1N4681 Zener diode can be used for voltage clamping, when a high transient voltage needs to be immediately clamped. It can be used as a protection device if an excessive voltage is encountered, thus protecting the other components from damage.The device is also used in analog and digital circuits to provide a reference voltage needed in high-accuracy applications. It is frequently employed as an adjustable circuit component to limit the output voltage of an amplifier. It can also be used to provide a linear voltage ramp, ideal for use as an adjustable delay element.The 1N4681 is available in a variety of package styles. Its axial form factor is a common type and other formats include surface-mount, small-outline, and DO-41 diode packages.The 1N4681 Zener diode is a highly reliable and cost-effective device, making it the choice of many engineers. With its wide operating temperature range, low forward voltage drop, and precise breakdown voltage, it can provide precise voltage regulation in a wide range of applications. It is also relatively easy to implement in production as it is available in various package types and form factors.
