Types of Zener Diodes Available
- 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.
- 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.
- 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.
