3EZ200D10/TR8 Application Field and Working Principle

Introduction

3EZ200D10/TR8 is a diode designed for its use in the fields of general electronics and power circuitry. It is a series of Zeners with a wide range of voltages and current ratings. This series of Zeners is especially useful for voltage regulation, power conversion, fail-safe protection, and interference suppression.

Application Field

This particular series of Zeners are ideal for use in communications equipment, control systems, automotive electronics, and consumer electronics. 3EZ200D10/TR8 is suitable for wide temperature range use in temperatures of up to 150°C. It can also be used as a constant voltage source, as well as current regulator, in high frequency circuits. Additionally, it can be used as a voltage limiter, in protection circuits, etc.

Features

3EZ200D10/TR8 has several important features. First, it is capable of handling continuous power up to 350 mW. It is also very compact with a maximum total device thickness of 0.5 mm. Additionally, this diodes employs thin (0.8 mm) lead design better suited for auto insertion processes.

Working Principle

Zener diodes, like 3EZ200D10/TR8, are designed to conduct current in both a forward and reverse or “Zener” direction. In the forward direction, a consecutive and regulated flow of current exits the diode. In the reverse direction, current flow is usually very low and is determined by the Zener voltage. The Zener voltage is the voltage that must be applied across the diode in order to produce Zener current, which is a small current that is necessary to maintain a constant voltage across the diode.

The number of volts that must be applied to the diode in order to create the Zener current depends on the type of diode and the amount of current that is needed. In the case of the 3EZ200D10/TR8, the Zener volts will be 10V. In the reverse direction, it is possible that the diode with conduct a significant amount of current, depending on the voltage applied. As the applied voltage is increased, the diode will start to conduct a greater amount of current as defined by the Zener diode’s voltage-current characteristics.

When the voltage applied to the diode is equal to the Zener voltage, the Zener current will be achieved and the voltage across the diode will equal the Zener voltage. This “breakdown” voltage is determined by the Zener voltage. As the voltage across the diode increases from the Zener voltage, the current through the diode increases exponentially. The diode will continue to operate at a constant voltage until the power rating of the diode is exceeded, at which point the diode will be destroyed.

Conclusion

3EZ200D10/TR8 is a Zener diode primarily used in general electronics, power circuitry, communications equipment, control systems, automotive electronics and consumer electronics. It has several features, such as its use in wide temperature ranges, capable of handling continuous power up to 350 mW, and having a maximum total device thickness of 0.5 mm. Its working principle describes how the diode’s current is determined by its Zener voltage, which is the voltage that must be applied across the diode in order to produce a small current necessary to maintain a constant voltage across the diode.
