Diodes - Zener - Single

ZPY20-TR is a single-package zener diode widely used in voltage regulation, particularly in the protection of circuits against transient over-voltage. This diode serves to limit the voltage by providing a controlled path for any excess voltage that might be encountered. It has a relatively low maximum breakdown voltage (20 V) and a fairly low maximum current (1.4A) that are suitable for many applications.The ZPY20-TR is a three terminal device, with an anode (bulk region) connected to a cathode (collector region) via a junction region, and a third terminal (zener region) connected to the anode via a junction region. The zener region acts as a resistor that controls the voltage flow between the other two terminals. A zener diode is usually used in a reverse-biased (reverse polarity) configuration, meaning that the anode is connected to the negative side of the voltage source and the cathode is connected to the positive side. The voltage across the diode increases until the breakdown voltage is reached, at which point current begins to flow.When the ZPY20-TR is operating correctly, voltage will remain at or below 20V regardless of the input voltage, keeping other components of the circuit at a safe level of current. A minimum load power of 1/8W must be applied to the ZPY20-TR, otherwise it could be damaged by overcurrent or overvoltage.In addition to voltage regulation, the ZPY20-TR can be used for voltage sensing and as a switching device. When a voltage is applied to the zener region, a current flows through the whole device, which can be used to detect changes in the input voltage. The diode can also be used as a switch when a voltage threshold is reached. These functions can be used in voltage control system applications such as motor control, over-voltage protection, lighting control, and switching power supplies.The ZPY20-TR is able to withstand 1000V surge and pulse voltages, as well as temperatures ranging from -55 to 150 degrees Celsius. This makes it suitable for use in a wide variety of environments. The diode also has a low impedance and a fast response time, making it suitable for applications where high frequency response is necessary.The ZPY20-TR is a reliable and versatile diode and is a popular choice for many applications that require voltage regulation and protection. Its low cost and reliable performance make it ideal for small, medium, and large-scale operations. Its wide range of voltage and temperature ratings make it suitable for a variety of applications, and its low impedance and fast response time make it suitable for use in high-frequency applications. The ZPY20-TR is a cost-effective, yet reliable solution for voltage regulation and protection.
