Description and Introduction

Zener TVSs The SMBJ43A is a Transient Voltage Suppressor (TVS) diode manufactured by Vishay. Here are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Peak Pulse Power (PPP):** 600 W (10/1000 µs waveform)  
- **Breakdown Voltage (VBR):** 47.8 V (min), 52.9 V (max)  
- **Standoff Voltage (VRWM):** 43 V  
- **Clamping Voltage (VC):** 69.4 V at 1 A  
- **Maximum Reverse Leakage Current (IR):** 1 µA at VRWM  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** SMB (DO-214AA)  

### **Descriptions:**
- The SMBJ43A is a unidirectional TVS diode designed to protect sensitive electronics from voltage transients and surges.  
- It is compliant with RoHS standards and halogen-free.  
- Suitable for high-speed data lines and power supply protection.  

### **Features:**
- **Low Clamping Voltage:** Provides effective transient suppression.  
- **Fast Response Time:** Reacts quickly to transient events (picosecond range).  
- **High Surge Capability:** Can handle large transient currents.  
- **Unidirectional Polarity:** Protects against positive transients only.  
- **Surface-Mount Package (SMB):** Compact and suitable for automated assembly.  

This information is strictly based on Vishay's datasheet for the SMBJ43A TVS diode.

Application Scenarios & Design Considerations

Zener TVSs

Alternative Part Number

  • P6SMB43A --: Same 600W SMB unidirectional TVS with 43V standoff, drop-in form factor and equivalent clamping performance.
  • 1SMB43AT3G --: SMB-packaged 400W-class unidirectional TVS with 43V standoff, widely available and electrically compatible for most surge protection designs.
  • SMAJ43A --: SMA-packaged 400W unidirectional TVS with 43V standoff; lower power rating but suitable as a smaller-footprint alternative where 600W is not mandatory.
