### **Descriptions:**
- The **SMCJ17A** is a **unidirectional** TVS diode designed to protect sensitive electronics from voltage transients and surges.  
- It is part of Vishay’s **SMCJ series**, offering high surge capability in a compact **DO-214AB (SMC)** package.  
- Suitable for **ESD protection, surge suppression, and transient voltage clamping** in various applications.  

### **Features:**
- **High power handling (1500W peak pulse power)**  
- **Low clamping voltage** for effective protection  
- **Fast response time** to transients  
- **RoHS compliant**  
- **AEC-Q101 qualified** (for automotive applications)  
- **UL recognized** (File E52744)  

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

Alternative Part Number

  • 1SMC17AT3G --: Same 1500W unidirectional TVS diode with 17V standoff voltage in the SMC package, directly interchangeable.
  • SMDJ17A --: 3000W SMC TVS diode with identical 17V standoff and clamping characteristics, offers higher surge rating as a drop-in upgrade.
  • P6SMB17A --: 600W SMB TVS diode with same 17V standoff voltage; lower power rating but suitable for less demanding clamping applications.
  • SMAJ17A --: 400W unidirectional TVS with identical 17V standoff voltage in SMA package; a compact alternative for lower-energy clamping applications.
  • 1SMB17AT3G --: Same 17V standoff unidirectional TVS in SMB package with 600W peak pulse rating; direct functional equivalent from a major supplier.
  • SMBJ17A --: Widely available 600W 17V unidirectional TVS in SMB package, electrically compatible drop-in replacement for the SMCJ17A.
