Description and Introduction

Zener TVSs The SMBJ54CA is a bidirectional TVS (Transient Voltage Suppressor) diode designed to protect sensitive electronics from voltage transients and surges.  

### **Manufacturer:**  
The SMBJ54CA is manufactured by multiple semiconductor companies, including:  
- **Littelfuse**  
- **Vishay**  
- **ON Semiconductor**  
- **STMicroelectronics**  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 54V  
- **Voltage - Breakdown (V_BR):** 60V (min)  
- **Voltage - Clamping (V_C):** 87.4V at 10A (typical)  
- **Peak Pulse Current (I_PP):** 10A (8/20µs)  
- **Power - Peak Pulse (P_PP):** 600W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package / Case:** SMB (DO-214AA)  

### **Descriptions & Features:**  
- **Bidirectional TVS Diode:** Protects against both positive and negative voltage transients.  
- **Low Clamping Voltage:** Provides effective protection for sensitive circuits.  
- **Fast Response Time:** Reacts quickly to transient events (typically in picoseconds).  
- **RoHS Compliant:** Meets environmental standards.  
- **Applications:** Used in power supplies, communication lines, automotive systems, and industrial electronics for surge protection.  

This information is based on standard datasheets from major manufacturers. For exact specifications, refer to the specific manufacturer's documentation.

Application Scenarios & Design Considerations

Zener TVSs

Alternative Part Number

  • P6SMB54CA --: Same 600W bidirectional TVS with 54V standoff in the SMB package, widely available and a direct functional drop-in.
  • 1SMB54CAT3G --: 600W bidirectional TVS diode with 54V working voltage in SMB, electrically equivalent and from a major supplier.
  • SMAJ54CA --: Bidirectional 400W TVS with 54V standoff in SMA; lower power rating but usable as a substitute where surge energy is modest.
