A 3EZ15DE3/TR12 is a single Zener diode, used for voltage regulation, that can handle up to 150 milliwatts (mW) of power without extra heat sinking. This diode is often used as an integrated circuit (IC) protection device, regulating the voltage to less than or equal to the zener breakdown voltage. Additionally, this model is suitable for general electronic applications due to its capability to handle higher voltages than other available zener diodes.

A Zener diode is a two-terminal semiconductor device that allows voltage to flow in the reverse direction when it reaches the Zener breakdown voltage. This assists in the regulation of a given voltage when there are fluctuations on the input voltage. When the parameters are set properly, the output voltage will remain as close as possible to the set voltage. The capacity of the diode will only allow flow up to a certain amount of current.

A 3EZ15DE3/TR12 includes a unidirectional zener element, with a mini SOD package (surface mounted device). It also has an extended- temperature range of up to 150 °C and is ideal for telecommunication, industrial and consumer applications. This type of diode is designed to handle up to 150mW, making it usable in junction circuits, such as motor controllers and power supplies.

When the diode’s reverse-Bias Voltage increases up to a particular point, the diode starts to conduct electricity in the reverse direction. This is known as the breakdown voltage of the diode. This breakdown voltage is usually written on the diode itself. This Voltage is known as the Zener Voltage and it remains the same, regardless of the amount of current is passing through the diode. This Voltage can be changed by changing the doping level of the semiconductor material which is inside the diode.

The Zener diode works on the principle of the junction diode, where it has two terminals – Anode and Cathode. When the Anode is connected to positive Voltage and the Cathode is connected to the negative Voltage, we are applying a forward Voltage. As a result, current starts to pass through the diode and we can achieve the Voltage stabilization of the system. After the breakdown Voltage is reached, the diode starts to conduct reverse voltage and the current starts to flow from the Cathode to Anode. If the Voltage reaches a certain level, the diode will conduct more current and the system will be stabilized.

The 3EZ15DE3/TR12 Zener diode is a highly reliable and durable device, capable of withstanding extreme temperature changes. It is designed to supply stable and consistent voltage regulation, which makes it perfect for protecting ICs and other semiconductor components in consumer and industrial applications. By utilizing this device, voltage levels in controllers and power supplies can be maintained and protected from unexpected voltage fluctuations.
