The 3EZ30DE3/TR8 is a diode in a 3mm long surface mount package. The device has a voltage range of 15V to 200V, with an ESD rating of 3500V. It is designed for applications where the current handling is low, such as in Zener references, load switches, and feedback elements.

Applications

The 3EZ30DE3/TR8 is mainly used as a Zener reference and load switch. Its low current consumption and wide voltage range make it suitable for applications that require performance from a small physical size. It can also be used in voltage regulator circuits and feedback applications, either as a stand-alone device or as part of an integrated circuit.

Working Principle

The 3EZ30DE3/TR8 is a Zener diode, which is designed to behave like a variable resistor when reverse-biased. When the applied voltage is below the Zener voltage, the diode acts as an open circuit, and no current flows. When the voltage exceeds the Zener voltage, the diode becomes forward-biased and begins to conduct. This makes the diode behave like a variable resistor, allowing current to flow when the voltage exceeds the Zener voltage. The Zener voltage can be adjusted by adjusting the diode\'s reverse-bias voltage.

Conclusion

The 3EZ30DE3/TR8 is a Zener diode designed for applications where current handling is low. It can be used as a Zener reference and load switch, a voltage regulator, or as a feedback element. The diode operates by acting as a variable resistor when reverse-biased, which allows current to flow when the applied voltage exceeds the Zener voltage. This makes it suitable for a variety of applications, including low-current applications.
