The PTZTE255.1A is a commonly used single Zener diode. It consists of a pair of diodes which are connected in series but the anode of one connects to the cathode of the other. When the polarity of the power source is reversed, the diodes become reverse-biased and the electrical field between them will force electrons to jump from one diode to the other. This reverse-biased action allows the electrons to flow from the negative to positive terminals of the battery.

The PTZTE255.1A\'s application field has a wide variety in sectors including the automotive industry and telecommunications. It is especially ideal for low-power applications such as regulating low-level voltages where security is an issue. It is also used in switches, LED lights, microcontrollers, and as zeners in microprocessors.

As for its working principle, the PTZTE255.1A works by using the same voltage breakdown that exists in any normal diode\'s junction. When the reverse voltage applied is greater than the Zener voltage, a current can flow and a breakdown occurs at the junction. By changing the size, shape and material of the dielectric barrier, the Zener voltage can be adjusted. This voltage is temperature dependent, so the device must be operating within temperature limits.

The breakdown mechanism of the PTZTE255.1A also allows it to function as a voltage regulator. The device is able to maintain almost a constant output voltage as long as the input voltage remains within certain range. It is also able to reduce the AC ripple found at the output of a voltage regulator by providing an additional voltage reference for the regulator.

The PTZTE255.1A is also used in surge suppression, although it is designed primarily as a Zener diode. It is able to absorb high energy spikes that could damage vital components. It also assists in reducing the effects of EMI (electromagnetic interference) since its voltage-controlled breakdown prevents high-frequency charge from passing through the device.

Overall, the PTZTE255.1A is a widely used single Zener diode with a wide range of applications. It has numerous advantages in both professional and consumer markets, and its capability to act as a voltage regulator provides an important additional layer of security for sensitive components. For these reasons, the PTZTE255.1A is an indispensable part of any electronics system.
