1EZ150D5/TR12

The 1EZ150D5/TR12 is a single Zener diode that is used in a variety of applications. Zener diodes have a unique characteristic, whereby the diode allows current to flow in one direction only, but will also allow current to flow the opposite way if the voltage is exceeded. This device is often used as a form of voltage regulation, or as a form of protection from overvoltage conditions.

General Information

The 1EZ150D5/TR12 is manufactured using a Silicon domed X1 die assembly, with a maximum operating temperature of 175°C. The device features a 2-pin package and is rated for a maximum voltage of 150V. The diode features a standard Zener voltage range of 5.1V, with 1% tolerance and an operating current of 5mA.

Application Fields

Zener diodes are commonly used in devices such as TV sets, computers, and communication equipment, where they are used to protect the device from overvoltage conditions. They are also used in automotive and aviation applications, where the use of a Zener diode can prevent damage from voltage spikes and surges. Additionally, Zener diodes can be used to regulate the output of a device, ensuring that a constant voltage is provided.

Working Principle

When a current passes through a Zener diode, the diode will ensure that the voltage across it remains constant. This is achieved through the movement of electrons between the N and P type semiconductor layers. When the voltage across the diode exceeds the Zener voltage, the N-type layer will become electrically neutral, allowing current to flow in the opposite direction. This will ensure that the voltage across the diode remains the same, no matter what external voltage is applied.

Conclusion

The 1EZ150D5/TR12 is a single Zener diode used in a variety of applications. It can be used for a range of purposes, from protecting devices from overvoltage conditions, to voltage regulation. The diode works by allowing current to flow in one direction only, but allowing current to flow the other way when the voltage exceeds the Zener voltage.
