Description and Introduction

Silicon Avalanche Diodes - 600W Surface Mount Transient Voltage Supressors The SMBJ440A is a transient voltage suppressor (TVS) diode designed to protect sensitive electronic components from voltage transients and electrical overstress.  

### **Manufacturer:**  
The SMBJ440A is manufactured by multiple semiconductor companies, including:  
- **Littelfuse**  
- **Vishay**  
- **STMicroelectronics**  
- **ON Semiconductor**  
- **Diodes Incorporated**  

### **Specifications:**  
- **Peak Pulse Power (10/1000μs):** 600W  
- **Standoff Voltage (V_RWM):** 440V  
- **Breakdown Voltage (V_BR):** 488V (min) to 539V (max)  
- **Clamping Voltage (V_C):** 712V at 1A  
- **Maximum Reverse Leakage Current (I_R):** 1μA at V_RWM  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** SMB (DO-214AA)  

### **Descriptions & Features:**  
- **Bidirectional TVS Diode** – Protects against both positive and negative voltage transients.  
- **Fast Response Time** – Responds to transients in nanoseconds.  
- **Low Clamping Voltage** – Limits voltage to safe levels for downstream components.  
- **RoHS Compliant** – Meets environmental standards.  
- **High Surge Capability** – Handles high transient energy.  
- **Applications:** Used in power supplies, communication systems, industrial controls, and automotive electronics for ESD and surge protection.
