1EZ180D2/TR12 is a single zener diode from the Diodes-Zener-Single category. This part is suitable for use as a voltage regulator, bypass in applications, or as an alternate current path in general circuit designs. Typical applications include powering and protecting microcontroller circuits, voltage regulation in automotive circuit designs, protection circuits in measuring devices, and transient suppression in telecom equipment.The working principle of the 1EZ180D2/TR12 diode is centered around its reverse-biased breakdown voltage. When the voltage polarity is reversed and the voltage applied to the diode reaches the breakdown voltage point, the electrical current begins to flow fast and the diode becomes conductive. Therefore, when the 1EZ180D2/TR12 is placed in a circuit with a voltage greater than the breakdown voltage, the excess current is bypassed around the part and regulated by the diode’s internal impedance.With its high speed reverse flow, the 1EZ180D2/TR12 diode is a popular choice for protecting sensitive electrical circuits from voltage spikes and transients. Bypassing the spiking voltage around the part helps to prevent permanent damage to the circuit, thus allowing the circuit to continue to perform its intended function.The 1EZ180D2/TR12 is most often used as a voltage regulator, providing a reliable power source to a circuit. When placed between the power source and the circuit, the 1EZ180D2/TR12 helps to prevent uncontrolled voltage fluctuations and power spikes that may disrupt the circuit’s function. This is especially helpful when the circuit is vulnerable due to low-quality power sources or fluctuations.The 1EZ180D2/TR12 is also widely used as a bypass in various applications. Placing the diode in parallel with a circuit can provide the circuit with an alternate current path if the main path is blocked orfails. The 1EZ180D2/TR12 can also be used to protect against electromagnetic interference (EMI). By connecting the diode between the EMI source and the vulnerable circuit, the diode helps to absorb the interference and prevent it from damaging the targeted circuit.The 1EZ180D2/TR12 is also used in general circuit designs, such as providing additional protection for microcontroller-based applications. When the device is connected at the microcontroller’s power supply, it helps to protect the microcontroller from voltage transients and spiking currents. This ensures that the microcontroller can regulate the flow of correct current to the other components connected in the design and operate smoothly.Overall, the 1EZ180D2/TR12 diode is a versatile and reliable single zener diode that can be used in virtually any circuit design. Its wide range of applications, along with its easy installation and ability to protect components from voltage spikes and transients, make it an invaluable addition to any circuit.
