SM16Z4689 is a dual power Zener diode array, which features an input of 16 Volts and a total of four diodes in a small SOT-23 package. It is an important component of today’s modern circuit designs, offering an effective way to protect against large voltage spikes, overvoltage, and powerline surge damage. The SM16Z4689 is well suited for both applications in industrial and consumer electronics.

A Zener diode’s main function is to protect a circuit from voltage spikes, overvoltage and other power surges. A Zener diode is basically a diode plus a Zener diode voltage regulator, which is designed with two or more closely spaced diodes in one package. The diodes in the package not only serve to protect against damage, but also to regulate the voltage. The four diodes in the SM16Z4689 package are designed in a way that helps to limit the output voltage to a pre-set value.

The working principle of the SM16Z4689 is based on the reversed breakdown voltage of the two lower voltage diodes in the package. When the input voltage rises to a preset level, the reversed breakdown voltage of the two lower voltage diodes will trigger and allow a limited current to flow. This current is then limited by the Zener voltage regulator and the internal resistance of the diode package.

This diode array can be used in a variety of applications, including power electronics, industrial control, automotive electronics, and displays. In power electronics applications, the SM16Z4689 can be used to provide voltage protection against transient surges and overvoltage conditions. It is also used to protect against reverse polarity and current limit conditions. In industrial control applications, the SM16Z4689 can be used to regulate supply voltage for panels and machine controllers.

In automotive and display applications, the SM16Z4689 can be used to protect circuits from transients and overvoltage conditions. It is also used to regulate the voltage for displays such as LCDs and other display devices. Additionally, the SM16Z4689 can be used to protect against overcurrent or short circuits.

The SM16Z4689 is a reliable, cost-effective solution for power electronics, industrial control, automotive and display applications. It offers protection against transients, overvoltage, reverse polarity and current limit conditions, as well as voltage regulation for displays. Additionally, the four Zener diodes in the package help to ensure stable output voltages and current levels. This makes the SM16Z4689 an excellent choice for any circuit protection related application.
