JAN1N4489CUS

Diodes - Zener - Single

The Jan1N4489CUS is a Zener diode designed to provide stable voltage regulation for small, low power installations. It is popular for use in battery-powered electronics, such as remote controls, toys, medical devices and industrial controls.

Stringent Voltage Regulation Requirements. The Jan1N4489CUS is designed with a low-power, low-noise design, which provides extremely reliable operation. It features a multi-tipped Zener design that helps ensure stable voltage regulation and eliminates thermal runaway problems. With an allowable voltage deviation of ±30mV, this diode is well suited for applications requiring stringent voltage regulation requirements.

Low Profile. One of the most notable features of the Jan1N4489CUS is its low profile. This means that not only is this diode great for use in tight-fitting spaces, but it can also be mounted flat on a board or panel, making it well suited for use in applications with limited space.

Wide Temperature Range. This Zener diode is designed to perform reliably in temperatures ranging from -55°C to +125°C, meaning it can be used in a wide variety of applications. With its low leakage current and low parasitic capacitance, this diode is capable of providing stable performance even in extreme temperatures.

High Peak Reverse Voltage. The Jan1N4489CUS has a peak reverse voltage of 30V, making it suitable for use in applications where a high voltage may occasionally be encountered.

Working Principle. This Zener is composed of components that work together in a complicated way. Electrons are emitted from a negatively-charged semiconductor material and travel towards a positively-charged anode. When these electrons reach the anode, they combine with positively-charged ions. This results in an electrical current that is equal in magnitude to the applied voltage, and the voltage across the diode remains relatively constant.

The Jan1N4489CUS is a reliable and cost-effective Zener diode designed for use in low power, high temperature applications. With its low profile, wide temperature range, and high peak reverse voltage, it is well suited for applications in which a stable voltage is required.
