2EZ51D10E3/TR12

The 2EZ51D10E3/TR12 is a single-pole Zener diode manufactured and marketed by Rohm. The device is designed for industrial and consumer applications as a low-dropout voltage regulator, providing approximately pH level regulation across a wide range of conditions. The unit is able to maintain a constant voltage and is suitable for a wide range of applications, including power supplies, undervoltage lockout, overvoltage protection and surge protection.

Application Field

The 2EZ51D10E3/TR12 is suitable for a range of applications, particularly those requiring low-dropout voltage regulation. It is typically used in consumer and industrial applications such as motor controllers, process control systems, air conditioning, security systems, and telecom applications. The device is also suitable for use in pulse transformers, as well as medical and biometric equipment.

Working Principle

The 2EZ51D10E3/TR12 operates on the principle of Zener breakdown. When a voltage greater than the Zener voltage is applied to the diode, the diode breaks down and the element is connected in a parallel circuit. This allows electrons to flow from the cathode to the anode—a phenomenon known as the Zener effect. When the voltage drops, the diode becomes reverse biased, isolating the anode from the circuit and maintaining a constant voltage.

Conclusion

The 2EZ51D10E3/TR12 is a single-pole Zener diode that provides phosphorus level regulation in a wide range of industrial and consumer applications. The unit features low-dropout voltage regulation, making it suitable for pulse transformers, motor controllers, process control systems, air conditioning, and security systems. The device employs the principle of Zener breakdown, with electrons flowing from the cathode to the anode when the diode is subjected to a voltage greater than the Zener voltage.
