JANTX1N4980C

JANTX1N4980C is a single high-current Zener diode that is widely used in many electronic applications, especially those that require low-noise, low-ripple voltage regulation. It is designed to provide stable and reliable voltage regulation in applications from 12 to 600V. This type of diode has a wide range of applications in many different fields, including power supply design, power conditioning, medical electronics, automotive electronics and industrial electronics.

The JANTX1N4980C is a standard, off-the-shelf Zener diode with a maximum storage temperature rating of 150°C and a voltage range of 12 to 600 volts. It features a low reverse leakage of 20 µA at 12V, and a maximum forward voltage of 1.25V. The diode also features a low-noise, low-ripple design and is rated for a peak reverse current of 4 Amps, allowing it to handle high-current applications. Additionally, it can also be used in high-voltage, high-current applications such as in DC-DC converter design.

The working principle of the Zener diode is based on the fact that when a current is passed through a diode in the forward biased direction, a small reverse current will flow at a certain threshold. This reverse current flow is known as Zener breakdown and this is how the Zener diode works. In the JANTX1N4980C, this threshold voltage is 12 volts, which means that if the forward voltage across the diode is greater than 12 volts, then a small reverse current will flow.

The most common application of a Zener diode is in voltage regulation. A Zener diode can be used in series with a resistor to form a voltage regulator circuit which will regulate the output voltage to a predetermined level. This circuit is used in many power supply and power conditioning applications such as battery chargers and AC-DC converters. In these applications, the Zener diode ensures that the regulated voltage never exceeds the preset level.

The JANTX1N4980C Zener diode can also be used in a variety of other applications such as TVS diode protection, voltage switching, amplifier bias over load protection, or pulse width modulation (PWM) control. It can also be used in reverse bias as an ESD protection device or even in transient voltage suppression (TVS) applications. It is also used in medical electronics for EMI/EMC protection.

In conclusion, the JANTX1N4980C is a versatile, high-current Zener diode with a wide range of applications. It is suitable for power supply design, power conditioning, automotive electronics and medical electronics, among others. It allows for a stable, consistent and reliable voltage regulation, and helps protect against high-current and high-voltage surge events. The working principle of a Zener diode is also well understood and its flexibility makes it an ideal choice for many applications.
