2EZ170D5

The 2EZ170D5 is a single Zener diode, ideal for use in low-power, low-voltage applications. It has a wide operating temperature range, making it well-suited for a variety of applications, including electronic medical and industrial controls, regulators and voltage references, and consumer electronics. Its low profile enables it to be mounted easily in confined spaces.

The 2EZ170D5 is a general-purpose, bilateral component that maintains a constant voltage on the anode regardless of variations in the cathode voltage. As with all Zener diodes, the 2EZ170D5 responds to both AC and DC signals and has two primary applications: voltage limiting and voltage regulation.

The 2EZ170D5 can be used for voltage limiting in a variety of circuits, including overvoltage protection, circuit-shutdown circuits, and inrush or overcurrent limiting. In voltage limiting applications, it can be used to protect sensitive components from high voltage spikes or to prevent overvoltage when connecting two incompatible power sources.

In voltage regulation applications, the 2EZ170D5 is used to create a reference voltage or to provide a stable power source for sensitive electronic components. It can be used in a voltage divider circuit to create a stable reference voltage or in a series-regulated power supply circuit to provide a constant output voltage.

The basic working principle of the 2EZ170D5 is based on the Zener diode\'s reverse-bias characteristics. A Zener diode is reverse-biased when the applied voltage is more negative than the diode\'s threshold voltage, also known as the Zener voltage. When reverse-biased, the diode exhibits a negative temperature coefficient, meaning that its threshold voltage decreases as the temperature increases. This allows the 2EZ170D5 to maintain a steady reference voltage across a wide range of operating temperatures.

In addition to its two primary applications, the 2EZ170D5 can also be used to create a semi-averaging reference voltage or protect against reverse current in switching power supplies. Its 7 mm x 4.5 mm surface mount package make it a popular choice for space-constrained applications.

In summary, the 2EZ170D5 is a versatile single Zener diode with a wide range of applications in low-power, low-voltage circuits. It can be used for voltage limiting, voltage regulation, or reverse current protection and its low profile surface mount package enables its use in confined spaces.
