Description and Introduction

1/2 Watt ZENER DIODES (2.28V to 50V) WIDE VOLTAGE RANGE The part **ZMM55-C2V4** is a Zener diode with the following specifications, descriptions, and features:  

### **Manufacturer Specifications:**  
- **Zener Voltage (Vz):** 5.5V  
- **Power Dissipation (P):** 500mW  
- **Tolerance:** ±5%  
- **Forward Voltage (Vf):** 1.2V (max)  
- **Reverse Leakage Current (Ir):** 5μA (max)  
- **Operating Temperature Range:** -65°C to +150°C  
- **Package:** DO-35 (Glass)  

### **Descriptions:**  
- The **ZMM55-C2V4** is a **5.5V 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 **low-power applications** such as voltage clamping, reference voltage generation, and surge protection.  

### **Features:**  
- **Precise voltage regulation** at 5.5V.  
- **Low leakage current** in the off state.  
- **Compact DO-35 package** for easy PCB mounting.  
- **Reliable performance** across a wide temperature range.  

This information is based strictly on the part's technical specifications. Let me know if you need further details.

Application Scenarios & Design Considerations

1/2 Watt ZENER DIODES (2.28V to 50V) WIDE VOLTAGE RANGE

Alternative Part Number

  • BZX55C2V4 --: Same 2.4V zener voltage in a DO-35 axial package, widely available and a common cross for ZMM55 series.
  • 1N5221B --: 2.4V zener diode with similar tolerance and power rating, standard DO-35 part often used as a substitute.
  • MMSZ5221B --: 2.4V surface-mount zener in SOD-123, suitable when a smaller SMD package is acceptable.
  • BZX79-C2V4 --: 2.4V zener in DO-35 package with tight tolerance and good availability, suitable functional substitute for the ZMM55-C2V4.
