Overview

3EZ150DE3/TR12 is a single Zener diode. It is a three-terminal electronically active device which is intended for use in applications that involve both power and signal level shifting. It is specifically designed to provide the specified voltage level shifting and provide isolation between circuits. Its operating characteristics and specifications depend on the specific application, that is, whether it is used as a power regulator, signal isolation device or in some other use.

Application Fields

3EZ150DE3/TR12 can be effectively used in a wide range of applications, including communications and consumer electronic products, such as modems, routers, digital cameras, televisions, and other consumer devices. It can also be used for Audio/visual equipment and access control systems, specifically to ensure signal isolation and voltage level shifting between various circuits. It is also suitable for use in various AC/DC switching power supplies. Additionally, this diode is equipped with an avalanche energy rating of 200mJ, and a peak pulses power dissipation rating of 10kW, making it suitable for emergency applications.

Working Principle

3EZ150DE3/TR12 is a three-terminal, electronically active device that uses the same basic principle as other Zener diodes: operation by diffusion of charge carriers, which occur when electrons and holes move across junctions in a circuit. Its operating characteristics and specifications depend on several factors: voltage level, current density, temperature, and junction material.

When a current is applied to the diode, it starts to conduct, creating an electric field in a depletion region, cutting off any voltage sources connected in parallel. At a certain point, the current density reaches a value that is defined by the breakdown voltage of the diode. At this point, the diode begins to break down, allowing for the voltage to be fixed at a value that is determined by the breakdown voltage. This allows for the predetermined voltage level to remain over a wide range of currents, temperatures, and junction materials.

Upon the application of a voltage, the 3EZ150DE3/TR12 is designed to regulate the voltage at the predetermined level, regardless of the current, temperature, or junction material. The voltage remains constant until the current density reaches a point that exceeds the breakdown voltage, at which point the diode will stop regulating the voltage.

Conclusion

3EZ150DE3/TR12 is a single Zener diode that is specifically designed to provide noise isolation, power regulation, and voltage level shift between different circuits. It is suitable for use in a wide range of applications, including communications and consumer electronics, Audio/visual equipment, and access control systems. Due to its avalanche energy rating of 200mJ, and peak pulses power dissipation rating of 10kW, it can also suitably for emergency applications. It operates based on the principle of charge carriers diffusion, creating an electric field in the depletion region, which cuts off any parallel voltage sources.
