Description and Introduction

Surface mount Silicon Planar Zener Diodes Here are the factual details about part **ZMM3.3** from Ic-phoenix technical data files:

### **Manufacturer Specifications**  
- **Part Number:** ZMM3.3  
- **Type:** Zener Diode  
- **Zener Voltage (Vz):** 3.3V  
- **Power Dissipation (Pd):** 500mW  
- **Forward Voltage (Vf):** 1.2V (typical)  
- **Maximum Reverse Leakage Current (Ir):** 5μA  
- **Operating Temperature Range:** -65°C to +150°C  
- **Package:** DO-35 (Glass Axial Lead Package)  

### **Descriptions**  
- The ZMM3.3 is a **3.3V Zener diode** designed for voltage regulation and protection in electronic circuits.  
- It operates in the **reverse breakdown region** to maintain a stable voltage across its terminals.  
- Commonly used in **voltage clamping, voltage reference, and surge suppression** applications.  

### **Features**  
- **Precise Voltage Regulation:** Maintains a stable 3.3V output under specified current conditions.  
- **Low Impedance:** Provides effective voltage clamping with minimal resistance.  
- **Reliable Performance:** Suitable for **low-power circuits** and general-purpose voltage stabilization.  
- **Axial Lead Package:** Easy to mount on PCBs or breadboards.
