Key Specifications:

- Zener Voltage (VZ): 5.1V at a test current of 5mA.

- Power Dissipation (Ptot): 500mW.

- Maximum Reverse Leakage Current: 100nA.

- Operating Temperature Range: -65°C to +150°C.

- Excellent stability and reliability due to its glass package and metallurgical bonding.

Application Circuits:

1. Voltage Regulator:

The BZV55-C5V1 is commonly used in simple voltage regulator circuits to provide a stable 5.1V output from a higher input voltage. A series current-limiting resistor is essential to ensure the diode operates within its specified current range.

2. Overvoltage Protection:

This Zener diode can protect sensitive ICs from voltage spikes by shunting excess current to ground when the voltage exceeds 5.1V. It is often placed parallel to the load or across the power supply lines.

3. Voltage Reference:

Due to its stable breakdown characteristics, the BZV55-C5V1 serves as an affordable voltage reference in analog circuits, ADC modules, and sensor interfaces.

4. Signal Clipping:

In audio or signal processing circuits, it can be used to clip input signals at precisely ±5.1V (when used in a back-to-back configuration), preventing amplifier saturation.

ICGOODFIND: The NXP BZV55-C5V1 Zener diode is a versatile component offering precise voltage regulation, overvoltage protection, and signal conditioning in compact designs. Its 5.1V breakdown voltage, low leakage current, and 500mW power rating make it a reliable choice for low-power applications.
