3EZ130D10E3/TR12

Diodes - Zener - Single is generally used to regulate voltage. The 3EZ130D10E3/TR12 is a single zener diode with a break down voltage at 10 V. It is about 3.2 mm in length and has a power dissipation of 500 mW with a tolerance of 5%.

Application Field:

The 3EZ130D10E3/TR12 is generally used in audio and radio frequency amplification circuits, transistor radio applications, and rectification circuits. It can be used in the switching power supply circuits to protect against excessive voltage fluctuations. It is also ideal for use in electronic timers, digital integrated circuits, and analog integrated circuits.

Working Principle:

A zener diode as a voltage regulator works by allowing current to pass through it in the forward-biased direction like any typical diode. When it is subjected to a higher voltage above its breakdown voltage, it goes into reverse-biased. This causes a voltage drop across the diode. When the voltage cross the diode reaches its reverse breakdown voltage, the current through the diode increases drastically and the voltage across the diode remains constant (or slightly decreases).

This phenomenon is what enables the 3EZ130D10E3/TR12 to regulate the voltage and prevent any further increase in the voltage once it reaches its breakdown voltage. It is analogous to a voltage-controlled current source as the current through the diode is controlled by the applied voltage. The breakdown voltage of the 3EZ130D10E3/TR12 diode is stated at 10 V and it can handle 500 mW of power.

The 3EZ130D10E3/TR12 is also a popular choice for power-supply voltage and circuit protection due to its low forward voltage drop and relatively high power dissipation. It is also fairly resistant to humidity, vibration, and heat-cycling, making it suitable for use in applications that require a robust protection against voltage fluctuations.

In conclusion, the 3EZ130D10E3/TR12 zener diode is a single zener diode that can regulate voltage and provide circuit protection in various electronics applications. It has a break down voltage at 10 V and a power dissipation of 500 mW with a tolerance of 5%. Its low forward voltage drop and relatively high power dissipation make it an ideal choice for a variety of applications, including audio and radio frequency amplification, transistor radio applications, and rectification circuits.
