Description and Introduction

TRANSIL The SMBJ26A-TR is a surface-mount transient voltage suppressor (TVS) diode manufactured by STMicroelectronics (ST).  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 26V  
- **Voltage - Breakdown (V_BR):** 28.9V (min)  
- **Voltage - Clamping (V_C):** 41.4V (max) at 10A  
- **Peak Pulse Current (I_PP):** 10A (8/20μs)  
- **Power - Peak Pulse (P_PP):** 400W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** SMB (DO-214AA)  
- **Mounting Type:** Surface Mount  

### **Descriptions:**  
The SMBJ26A-TR is designed to protect sensitive electronics from voltage transients and surges. It provides fast response to overvoltage events, clamping excessive voltage to safe levels.  

### **Features:**  
- Low clamping voltage  
- Fast response time  
- High surge capability  
- RoHS compliant  
- Surface-mount package for automated assembly  

This diode is commonly used in applications such as power supplies, communication equipment, and automotive systems for ESD and surge protection.

Application Scenarios & Design Considerations

TRANSIL

Alternative Part Number

  • P6SMB27A --: Same SMB (DO-214AA) package unidirectional TVS with 26V standoff class; 27A clamping is close and widely available as a drop-in.
  • SMAJ26A --: Unidirectional 26V standoff TVS in SMA package; electrically equivalent for many clamp applications, though a smaller package requires layout check.
  • 1SMB26AT3G --: 26V standoff unidirectional TVS in SMB package from a major supplier, suitable as a functional replacement with similar surge rating.
