Description and Introduction

500mW SURFACE MOUNT ZENER DIODE The part **ZMM6V8** is a **Zener diode** manufactured by **STMicroelectronics (ST)**. Below are the key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Zener Voltage (Vz):** 6.8V  
- **Power Dissipation (Pd):** 500mW  
- **Forward Voltage (Vf):** 1.2V (typical at 200mA)  
- **Maximum Reverse Leakage Current (Ir):** 5µA (at 4V)  
- **Operating Temperature Range:** -65°C to +150°C  
- **Package:** DO-35 (Glass)  

### **Descriptions:**
- The **ZMM6V8** is a **6.8V 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, voltage reference, and surge suppression.  

### **Features:**
- **High reliability** with stable voltage regulation.  
- **Low impedance** under breakdown conditions.  
- **Glass package (DO-35)** for durability and compactness.  
- **RoHS compliant** (lead-free).  

This information is strictly based on the manufacturer's datasheet for the **ST ZMM6V8 Zener diode**.

Application Scenarios & Design Considerations

500mW SURFACE MOUNT ZENER DIODE

Alternative Part Number

  • BZX55C6V8 --: 6.8V zener diode in the same DO-35 package with comparable power rating, widely available and a common cross for ZMM series parts.
  • 1N4736A --: 6.8V 1W zener diode in DO-41 package, a standard industry part that can replace the ZMM6V8 in most applications with adequate board space.
  • BZX79C6V8 --: 6.8V zener diode in DO-35 package with similar voltage tolerance and power rating, suitable drop-in alternative for general-purpose regulation.
  • MMSZ5235B --: 6.8V 500mW zener diode in SOD-123 surface-mount package, suitable when a smaller SMD form factor is acceptable and offering comparable electrical characteristics.
  • BZT52C6V8 --: 6.8V zener diode in SOD-123 package with similar power rating and tolerance, widely available and electrically compatible.
