### **Descriptions & Features:**  
- **Bidirectional TVS Diode** for surge protection in electronic circuits.  
- Designed to protect sensitive components from **ESD, lightning, and other transient voltage events**.  
- **Low clamping voltage** ensures effective protection.  
- **High surge capability** (1500W peak pulse power).  
- **RoHS compliant** and halogen-free.  
- Suitable for **automotive, industrial, and telecom applications**.  

For detailed datasheets, refer to **STMicroelectronics' official documentation**.

Application Scenarios & Design Considerations

TRANSIL

Alternative Part Number

  • 1SMC85CA --: Same 1500W bidirectional TVS diode with 85V standoff voltage in the SMC (DO-214AB) package, direct functional equivalent.
  • SMDJ85CA --: 3000W bidirectional TVS with 85V standoff in SMC package; higher surge rating provides margin while remaining drop-in compatible.
  • P6SMB85CA --: 600W bidirectional TVS with 85V standoff; lower power rating but suitable for less demanding clamping applications in a smaller SMB package.
  • 1SMC85CAT3G --: Same 1500W bidirectional TVS class with 85V standoff voltage, directly interchangeable for transient clamping.
  • SMBJ85CA --: Bidirectional 85V TVS diode with similar clamping performance; lower power rating (600W) so verify surge requirements.
