Description and Introduction

600W SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR The SMBJ50CA is a bidirectional TVS (Transient Voltage Suppressor) diode manufactured by Vishay. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 50V  
- **Voltage - Breakdown (V_BR):** 55.5V (Min), 61.4V (Typ), 67.4V (Max)  
- **Voltage - Clamping (V_CL):** 81.4V (Max) @ 10A (I_PP)  
- **Peak Pulse Current (I_PP):** 10A (8/20μs)  
- **Power - Peak Pulse (P_PP):** 600W (8/20μs)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** SMB (DO-214AA)  

### **Description:**  
The SMBJ50CA is designed to protect sensitive electronics from voltage transients, such as ESD (Electrostatic Discharge), lightning, and inductive load switching. It is bidirectional, meaning it clamps both positive and negative transients.  

### **Features:**  
- **Bidirectional TVS Diode**  
- **Low Clamping Voltage**  
- **Fast Response Time**  
- **High Surge Capability**  
- **RoHS Compliant**  
- **Lead-Free & Halogen-Free**  

This diode is commonly used in power supplies, communication systems, and automotive applications for transient protection.

Application Scenarios & Design Considerations

600W SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR

Alternative Part Number

  • P6SMB56CA --: Bidirectional 600W SMB TVS diode with comparable standoff voltage and clamping performance, direct drop-in replacement in the same SMB package.
  • 1SMB58CA --: Bidirectional 600W SMB transient voltage suppressor with similar breakdown voltage range, widely available and electrically compatible.
  • SMAJ58CA --: Bidirectional 400W SMA TVS diode offering similar clamping voltage; lower power rating but suitable for many protection designs, with a different series naming for easy distinction.
