High-Quality Zener Diodes for Power and Voltage Control

Zener diodes are crucial components in electronic circuits, specifically designed for voltage regulation. These diodes are engineered to maintain a constant voltage across circuits, even when variations in input voltage or load occur. At Evelta, we offer a wide range of Zener diodes from leading manufacturers such as Nexperia, Diodes Incorporated, and Vishay Semiconductors. Our catalog includes Zener diodes suited for applications ranging from low-voltage regulation to high-power circuits, ensuring reliable performance and precise voltage control.

Types of Zener Diodes Available

  1. Low Voltage Zener Diodes These diodes are designed for applications requiring lower voltage regulation, typically under 10V. A standout product in this category is the BZT52C4V7-7-F - 4.7V 500mW Zener Diode 2-Pin SOD123, which is ideal for protecting low-power circuits from voltage fluctuations. With a breakdown voltage of 4.7V and compact SOD123 packaging, this diode is perfect for use in mobile devices, sensors, and other portable electronics.
  2. Medium Voltage Zener Diodes Medium voltage Zener diodes are suitable for more robust applications that require higher voltage regulation. An example is the BZV55-C5V1 - 5.1V 5% 500mW Voltage Regulator Zener Single Diode SOD80C, offering a breakdown voltage of 5.1V with 5% tolerance. It ensures precision in circuit regulation while minimizing power dissipation, making it an ideal choice for power supply circuits and signal processing.
  3. High Voltage Zener Diodes For applications requiring higher voltage regulation, such as industrial and automotive electronics, high voltage Zener diodes like the SML4749A-E3/61 - SML4749 Series 24V 1W 5% Zener Diode SMA 2Pin DO-214AC provide the perfect solution. This diode is designed to handle up to 24V and 1W of power, making it suitable for protecting circuits from overvoltage conditions in high-power applications.

Key Features and Benefits

  • Precise Voltage Regulation: Zener diodes are specifically designed to maintain a constant voltage across various load conditions, ensuring the protection and stability of sensitive components in electronic circuits.
  • Low Power Dissipation: Many Zener diodes, like the BZT52C4V7-7-F, are optimized for efficiency, minimizing power loss even in low-voltage applications. This makes them perfect for battery-powered devices where conserving power is essential.
  • Reliable Performance in High-Temperature Environments: Zener diodes are built to perform reliably, even in challenging environments with high temperatures, making them suitable for industrial and automotive applications.
  • Compact Designs: Zener diodes come in various surface-mount packages, such as the SOD123 and SOD80C, ensuring easy integration into space-constrained designs without sacrificing performance.

Applications of Zener Diodes

Zener diodes are used in a wide range of electronic applications, from consumer electronics to industrial systems. Their ability to provide precise voltage regulation makes them indispensable for protecting and stabilizing sensitive components.

  • Voltage Regulation in Power Supplies: Zener diodes are commonly used in power supply circuits to provide a stable output voltage, protecting sensitive components from voltage spikes and fluctuations. The BZV55-C5V1, for example, is perfect for use in voltage regulation circuits in power supplies for small electronic devices.
  • Overvoltage Protection: In automotive and industrial systems, high-voltage Zener diodes like the SML4749A-E3/61 help prevent overvoltage damage by clamping excess voltage and dissipating it safely.
  • Signal Conditioning: Zener diodes are used to protect and regulate signal levels in communication and data transmission systems, ensuring that signals remain within defined voltage limits.
  • Battery Protection Circuits: In battery-operated devices, low-power Zener diodes like the BZT52C4V7-7-F ensure that overvoltage conditions do not damage the battery or connected circuits, extending the life of the device and preventing potential failures.
