### **Descriptions and Features:**  
- High-efficiency Schottky barrier rectifier  
- Low forward voltage drop for reduced power loss  
- High surge current capability  
- Lead-free and RoHS compliant  
- Surface mount package (SMP/DO-220AA) for compact PCB designs  
- Suitable for high-frequency switching applications  

This diode is commonly used in power supplies, DC-DC converters, and reverse polarity protection circuits.

Application Scenarios & Design Considerations

TRISIL

Alternative Part Number

  • P6SMB120A --: SMB-packaged transient voltage suppressor with 120V standoff voltage, similar clamping performance and drop-in footprint.
  • SMAJ120A --: SMA TVS diode rated 120V standoff, unidirectional, suitable replacement where slightly lower power rating is acceptable.
  • SMBJ120A --: SMB unidirectional TVS with 120V standoff and 600W peak pulse power, close electrical match to the SMP30 series.
