The 3EZ170D2E3/TR8 is a single Zener diode, designed to provide voltage regulation. It is commonly used in power supplies, DC/DC converters, and other applications covering a wide variety of areas, including automotive, instrumentation, and communication equipment. The diode operates in an avalanche mode, meaning that when it is exposed to a high enough voltage, the diode will “break down,” allowing current to flow. This breakdown voltage is consistent and reliable, making it ideal for a variety of different applications.

The 3EZ170D2E3/TR8 comes in a tiny SOT-23 package, making it extremely small and easy to work with. It has a maximum voltage rating of 170 volts and a maximum reverse current rating of 1.0 mA. It also has a wide temperature range, making it suitable for use in a wide range of environments. Additionally, the 3EZ170D2E3/TR8 has a very low general capacitance of 4.5 pF, making it suitable for high-speed applications such as communications and data transmission.

When used as a voltage regulator, the 3EZ170D2E3/TR8 works by limiting the maximum voltage output to its breakdown voltage (which is marked on the datasheet as VZ). When the output voltage reaches VZ, the diode begins to break down, allowing current to “leak” through it and reducing the output voltage to VZ. This limits the maximum voltage output to VZ, protecting any other components connected to the output from damage due to excessive voltage.

The 3EZ170D2E3/TR8 can also be used in reverse bias applications, where it acts as a current limiter. In this application, the diode is connected in reverse and when the voltage reaches the breakdown voltage, the current is limited to a safe value. This prevents current damaging any sensitive components, and protecting things such as transistors and integrated circuits.

In addition to voltage and current regulation applications, the 3EZ170D2E3/TR8 can also be used as a simple on/off switch. In this application, the diode is connected in series with a load, and when a voltage source is applied, the diode breaks down, allowing current to flow through the load. This makes the diode ideal for applications such as DC motor control, where the diode can be used to turn a motor on and off quickly.

The 3EZ170D2E3/TR8 is an excellent choice for any application requiring reliable and consistent voltage and/or current regulation. Its small package size, wide temperature range, and low capacitance make it ideal for a variety of applications, from power supplies and DC/DC converters to motor control and data transmission. No matter the application, the 3EZ170D2E3/TR8 is sure to provide reliable and consistent performance.
