Description and Introduction

Surface mount Silicon Planar Zener Diodes The part **ZMM4.7** is a Zener diode manufactured by **DIODES**. Below are its key specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Zener Voltage (Vz):** 4.7V  
- **Power Dissipation (Pd):** 500mW  
- **Tolerance:** ±5%  
- **Forward Voltage (Vf):** 1.2V (typical)  
- **Maximum Reverse Leakage Current (Ir):** 5µA (at 1V)  
- **Operating Temperature Range:** -65°C to +150°C  
- **Package Type:** DO-35 (Glass)  

### **Descriptions:**  
- The **ZMM4.7** is a **4.7V 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.  
- Suitable for **general-purpose applications**, including voltage clamping, regulation, and transient suppression.  

### **Features:**  
- **Low impedance** in the Zener breakdown region.  
- **High reliability** with glass encapsulation.  
- **Compact size** (DO-35 package) for space-constrained designs.  
- **RoHS compliant** (lead-free).  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Surface mount Silicon Planar Zener Diodes

Alternative Part Number

  • BZX55C4V7 --: 4.7V 500mW zener diode in a DO-35 package, a widely available industry-standard equivalent to the ZMM4.7 with similar voltage tolerance and power rating.
  • 1N4732A --: 4.7V 1W zener diode in DO-41 package, offers higher power margin and is a very common cross-reference for 4.7V zener applications.
  • MMSZ4688T1G --: 4.7V zener diode in SOD-123 surface-mount package, suitable when a smaller SMD form factor is acceptable and provides good voltage regulation.
  • BZT52C4V7 --: 4.7V zener in the SOD-123 surface-mount package with similar tolerance and power rating, widely available and a common drop-in substitute for leaded zener diodes.
  • MMSZ5230B --: 4.7V zener diode in SOD-123 package with 500mW rating, matching voltage and tolerance class, suitable for voltage regulation and clamping applications.
