#### **Descriptions:**  
- The ZMM22 is a 22V Zener diode designed for voltage regulation and protection in electronic circuits.  
- It provides stable voltage clamping when operated in the reverse breakdown region.  
- Suitable for general-purpose applications in power supplies, voltage references, and surge protection.  

#### **Features:**  
- **Precision Voltage Regulation:** Maintains a stable 22V output within a ±5% tolerance.  
- **Low Leakage Current:** Ensures minimal power loss in standby conditions.  
- **High Reliability:** Robust glass DO-35 package for durability.  
- **Wide Temperature Range:** Operates effectively in harsh environments.  

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