- Suitable for applications requiring precise voltage clamping or regulation.  

### **Features:**  
- High power dissipation capability (1.5W).  
- Compact SMA package for space-saving PCB designs.  
- Low reverse leakage current.  
- Reliable performance across a wide temperature range.  
- RoHS compliant.  

For detailed electrical characteristics and application notes, refer to the official DIOTEC datasheet.

Application Scenarios & Design Considerations

Surface mount Silicon-Zener Diodes (non-planar technology)

Alternative Part Number

  • SMAJ3.9A --: Same SMA package unidirectional TVS diode with 3.9V standoff, directly interchangeable for clamping applications.
  • P4SMA3.9A --: SMA-packaged 400W TVS diode with matching 3.9V working voltage, suitable drop-in replacement.
  • SMA5J3.9A --: SMA TVS diode with 3.9V standoff and similar surge rating, usable alternative when exact pulse rating is not critical.
