UDZSTE-1713B is a type of diode, more specifically a Zener diode. Zener diodes are specially designed to work the other way round from a normal diode.

A normal diode will only allow current to flow through in one direction, while a Zener provides a regulated voltage source that is reversed biased and conducts electricity on both its anode and cathode. When the doped pn junction reaches breakdown voltage, it will turn on and create a channel that passes an electric current through it. The UDZSTE-1713B is rated at 13 volts, meaning the diode is designed to turn on at that voltage.

The application field of the UDZSTE-1713B is within power supplies, where it helps protect circuits from overvoltage conditions. When normal voltage is applied the diode acts like an open circuit, but when the voltage exceeds the rated breakdown voltage, the diode will turn on and draw the current away from the voltage source. This prevents components from being damaged by excessive voltage, and thus increases the reliability of the circuit.

The working principle of the UDZSTE-1713B is relatively simple. When the voltage applied to the anode and cathode exceeds the breakdown voltage, the diode will turn on and allow a current to pass through. The doped pn junction of the diode draws electrons into the junction, which gives off a photon that is released back into region between the two ends, which act like a supplementary negative potential well and helps the electrons to cross over.

When the UDZSTE-1713B operates in reverse voltage mode, the diode will act like a Zener diode and regulate the reverse voltage. The controlled flow of current limits the voltage applied to the diode and prevents higher voltages from flowing through it. This makes the UDZSTE-1713B very useful in power supply applications, where it helps protect from overvoltage damage.

To summarize, the UDZSTE-1713B is an example of a Zener diode that is rated at 13 volts. It is typically used in power supplies to regulate voltage and protect components from overvoltage damage. The diode has a doped pn junction that ensures it turns on when the voltage reaches the breakdown voltage rate. Finally, when the rated voltage is applied in reverse, the diode acts like a Zener diode and will regulate the current accordingly.
