DZ2W30000L application field and working principle

Diodes’ Zener diodes are unidirectional devices used to ensure that the voltage levels remain within required limits. Zener diode DZ2W30000L is a voltage regulator diode designed for general-purpose use. It has a very low leakage current and high reverse current capabilities. With a maximum of 30V, maximum power this diode offers reasonable heat dissipation and better protection.

Introduction

Zener diodes are widely used in electronics applications where a stabilized voltage is needed, either as a reference or as an active element. Zener diode DZ2W30000L incorporates all the features of a bidirectional diode device with a single junction. Its high reverse current capabilities make it particularly suitable for applications where high currents are likely to be encountered.

Application fields

The application fields of this voltage regulator diode are mainly:

• Voltage regulation
• EMI/RFI filters
• Clipping and clamping circuits
• Voltage stabilization for AC/DC power systems
• Biasing amplifiers, converters, and oscillators
• Switching and logic circuits
• Clocks and timer circuits

Working principle

The working principle of Zener diode DZ2W30000L is based on the principle of breakdown due to electric field. When the reverse bias is applied to the diode, the electric field strength increases and reaches a level at which it causes the rapid breakdown of the reverse current. As a result, the reverse current increases, limiting the voltage across the diode and thus providing voltage regulation.

Benefits

• Robust resistance to high-frequency noise and EMI
• High thermal stability and high reliability
• Very low leakage current
• Low forward voltage drop
• Low thermal resistance and good total power dissipation
• Low reverse saturation voltage

The DZ2W30000L is a great choice for applications where a steady voltage is required, such as in power supplies, motor drives, and communication systems. It offers good heat dissipation, relatively low cost, and high reliability.
