The 1N4731E3/TR13 is a 3 volt, 1 watt Zener diode, designed to regulate DC power systems. It is categorized under diodes - Zener - Single. It is widely used for voltage regulation in power supplies, clamp, and memory protection.

The Zener diode is a semiconductor diode that allows electrical current to flow in one direction as a regular diode, but also in the opposite direction when the zener breakdown voltage, or zener voltage, is reached. When the zener voltage is reached, the current through the diode increases exponentially and above it, the reverse voltage is kept approximately constant. This constant voltage can be used to regulate or stabilize voltage.

The 1N4731E3/TR13 diode can be characterized by its breakdown voltage and its dynamic resistance value. The breakdown voltage is 3V, which means that the diode conductance increases exponentially when the reverse-biased voltage reaches 3V. This is useful for creating a stable and consistent voltage. The dynamic resistance, or dynamic impedance, is a measure of the variation in the current vs. voltage relationship in one direction and the reverse direction of the diode. Dynamic resistance is used to determine the performance of the diode under different conditions, such as an AC input.

The 1N4731E3/TR13 is an ideal choice for applications involving reliable voltage regulation, such as in AC/DC voltage converters and DC/DC voltage regulators. It is also used in power supplies, clamp circuits, memory protection circuits, and as a low impedance switch mode power supply. It can be used in many other electronic circuits, such as protection circuits and switching regulators, as well as other DC power applications.

The 1N4731E3/TR13 diode is a reliable, low-cost solution for many applications. Its 3V breakdown voltage and its low dynamic resistance provide reliable voltage regulation and enable stable operation even under different operating conditions. Its low price and high performance make it an ideal choice for applications requiring reliable voltage regulation.
