Description and Introduction

TRANSIL The SMBJ40A-TR is a surface-mount transient voltage suppressor (TVS) diode manufactured by STMicroelectronics.  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 40V  
- **Voltage - Breakdown (V_BR):** 44.4V (min)  
- **Voltage - Clamping (V_CL):** 64.4V at 10A (I_PP)  
- **Peak Pulse Current (I_PP):** 10A (8/20µs)  
- **Power - Peak Pulse (P_PPM):** 400W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package / Case:** SMB (DO-214AA)  
- **Mounting Type:** Surface Mount  
- **Polarity:** Unidirectional  

### **Descriptions:**  
The SMBJ40A-TR is designed to protect sensitive electronics from voltage transients and surges, such as ESD, lightning, and inductive load switching. It provides fast response times and high surge capability.  

### **Features:**  
- **Low Clamping Voltage:** Ensures effective protection for sensitive circuits.  
- **High Surge Capability:** Can handle high transient currents.  
- **Fast Response Time:** Reacts quickly to transient events.  
- **RoHS Compliant:** Meets environmental standards.  
- **Unidirectional Protection:** Suitable for DC applications.  

This device is commonly used in power supplies, communication equipment, and automotive electronics for overvoltage protection.
