Description and Introduction

TRANSIL The SMBJ5.0A-TR is a surface-mount TVS (Transient Voltage Suppressor) diode manufactured by STMicroelectronics (ST).  

### **Specifications:**  
- **Voltage - Reverse Standoff (Vr):** 5V  
- **Voltage - Breakdown (Vbr):** 6.4V (min) to 7.07V (max)  
- **Voltage - Clamping (Vc):** 9.2V at 1A  
- **Peak Pulse Current (Ipp):** 4.6A (8/20µs)  
- **Power - Peak Pulse:** 400W (8/20µs)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package / Case:** SMB (DO-214AA)  
- **Mounting Type:** Surface Mount  
- **Polarity:** Unidirectional  

### **Descriptions:**  
The SMBJ5.0A-TR is designed to protect sensitive electronics from voltage transients, including ESD (Electrostatic Discharge), lightning, and other surge events. It provides fast response times and high surge capability.  

### **Features:**  
- Low clamping voltage  
- High surge capability  
- Fast response time  
- RoHS compliant  
- AEC-Q101 qualified (for automotive applications)  

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

Application Scenarios & Design Considerations

TRANSIL

Alternative Part Number

  • P6SMB6.8A --: Unidirectional SMB TVS diode with similar 600W peak pulse power and a slightly higher standoff voltage, suitable as a robust drop-in replacement for 5V rail protection.
  • SMAJ5.0A --: Unidirectional 400W TVS in SMA package with the same 5.0V standoff and clamping behavior; lower power rating but pin-compatible footprint for many designs.
  • 1SMB5.0AT3G --: Unidirectional 600W SMB TVS with identical 5.0V standoff voltage and similar clamping characteristics, from a different series and manufacturer.
