Diodes - Zener - Single

The SZ1SMB5946BT3G is part of a family of Zener products manufactured by NXP Semiconductors. It is a low-voltage Zener Single Diode designed for use in both commercial and industrial applications. The product is provided in a SMB surface mount package.

The diode provides stabilized, regulated low voltage and is useful for maintaining low output voltage levels in circuits, such as protection and stabilization applications. It can also be used as a voltage reference in between other components on a board or mobile device. The diode is packaged in a standard SOT363 body type that includes a 3 pad configuration, allowing for easier assembly and improved short-term operation. The product is also very robust, with an operating temperature range of -55 C up to 125 C.

Application fields

The SZ1SMB5946BT3G Zener Single Diode is commonly used in the following types of applications:

• Mobile / Cell Phones
• Computer Motherboards
• Automotive Electronic Control Units (ECUs)
• MRI and High Efficiency Power Supplies
• Battery Chargers
• Industrial Applications
• High Speed Networking Equipment

Some of the advantages of using this product for these types of applications are its low leakage current, small capacitance values, and high performance.

Working principle

This Zener Single Diode works through a reverse-polarity process, where the voltage of the input is lower than the break-down voltage. This process takes place as a result of the diode’s ability to allow an electrical current to pass through the diode in one direction, while preventing current from flowing in the opposite direction. The current flowing through the diode reaches a maximum value for the specified voltage, allowing the diode to regulate a steady voltage output. This process is also known as Zener breakdown.

The diode also uses a temperature coefficient that helps maintain the diode’s low current reversible behavior. The temperature coefficient, also known as the TK or temperature coefficient delta, is a factor that tells us how the value of the diode’s output voltage changes with a certain increase or decrease in temperature.

Since the SZ1SMB5946BT3G is a Zener Single Diode, it is specifically designed to prevent high voltage transients from passing through the diode, while still maintaining a steady output voltage.

Conclusion

The SZ1SMB5946BT3G Zener Single Diode is an excellent solution for a variety of applications where a low voltage and stable output is required. The product is designed to provide efficient voltage regulation and protection against high voltage transients. It is also provided in a small package and has a wide operating temperature range, allowing it to be used in many different environments and applications.
