The **MAZ21300AG** is a specific type of **Zener Diode** manufactured by Panasonic. It is part of the MAZ2xxx series, designed for voltage regulation and surge protection in electronic circuits. --- ### 1. Technical Specifications The core characteristics of the MAZ21300AG define its performance in a circuit: | Parameter | Value / Range | | :--- | :--- | | **Zener Voltage ($V_z$)** | 13.0V (Typical) | | **Power Dissipation ($P_d$)** | 200 mW | | **Zener Voltage Range** | 12.4V to 13.7V | | **Package Type** | Mini2-G3 (SMD/SMT) | | **Configuration** | Single Diode | | **Material** | Silicon (Planar Type) | --- ### 2. Key Features * **Small Footprint:** The Mini2-G3 package is designed for high-density surface mounting, making it ideal for compact consumer electronics. * **Voltage Regulation:** It provides a stable reference voltage of approximately 13V. * **Reliability:** It is built using silicon planar technology, which ensures low noise and high reliability over time. --- ### 3. Pinout and Internal Structure In its standard SMT package, the device typically has two terminals: 1. **Anode:** The positive side during forward bias. 2. **Cathode:** Marked with a band; in Zener mode (reverse bias), this is where the positive voltage is applied to achieve regulation. ```mermaid graph LR A[Anode] ---|>|--- K[Cathode / Band] ``` --- ### 4. Typical Applications The MAZ21300AG is commonly found in the following circuit types: * **Voltage Limiting:** Protecting sensitive integrated circuits (ICs) from voltage spikes that exceed 13V. * **Constant Voltage Sources:** Providing a steady 13V reference for sensors or analog-to-digital converters. * **Waveform Clipping:** Used in signal processing to "clip" the peaks of an electrical waveform. ---
