• Power supply isolation
• Battery protection

JAN1N4099C-1 is particularly suited for use in automotive, portable, and home electronics, as well as in telecommunication, computer, and industrial applications.

Working Principle

Unlike ordinary Zener diodes, JAN1N4099C-1 diodes contain two differently doped segments. The diode functions as a variable resistor, or impedance, as shown in Figure 1. As the applied voltage increases, the current increases and the voltage across the diode decreases. The current then flows through the diode in both directions.

JAN1N4099C-1 has an exceptionally low temperature coefficient (TC) of approximately 0.07% per °C. This enables the diode to maintain its nominal breakdown voltage over a wide range of temperature ranges, and also ensures that the dynamic resistance is close to its nominal value. Additionally, the low speed turn-on time ensures that the diode can be used in applications that require fast response times.

In applications requiring noise reduction, the low noise JAN1N4099C-1 diode can be used to reduce conducted and radiated noise. When the noise frequencies are within the diode\'s passband, the diode can be used to effectively reduce noise.

Conclusion

The JAN1N4099C-1 diode is a low-noise, low-temperature single Zener diode that can be used in a variety of applications, including voltage regulation, current switching, current limiting, and surge protection. Its low temperature coefficient and fast turn-on time makes it ideal for use in automotive, portable, and home electronics, as well as in telecommunication, computer, and industrial applications. Additionally, its low noise characteristics make it well suited for applications requiring noise reduction.
