- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  
- **RoHS Compliant:** Yes  

### **Descriptions:**  
- Designed to protect sensitive electronics from voltage transients and surges.  
- Provides high surge capability in a compact SMC package.  
- Suitable for applications requiring robust overvoltage protection.  

### **Features:**  
- **Low Clamping Voltage:** Ensures effective protection for sensitive components.  
- **High Surge Capacity:** Capable of handling large transient currents.  
- **Fast Response Time:** Reacts quickly to transient events.  
- **Uni-directional Polarity:** Protects against positive transients only.  
- **Surface Mount Package:** Suitable for automated assembly processes.

Application Scenarios & Design Considerations

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR VOLTAGE-5.0 TO 170 Volts 3000 Watt Peak Pulse Power

Alternative Part Number

  • SMAJ45A --: Same 45V standoff unidirectional TVS in the SMAJ series; lower power rating (400W vs 3000W) but pin-compatible SMD package, suitable for lower-surge applications.
  • SMCJ45A --: 1500W unidirectional TVS with 45V standoff in SMC package; close electrical match with lower surge capability than the 3000W SMDJ45A.
  • 5.0SMDJ45A --: 5000W unidirectional TVS with 45V standoff in SMC package; higher surge rating than SMDJ45A and a direct functional upgrade for transient protection.
  • P6SMB45A --: 45V standoff unidirectional TVS with 600W rating in SMB package; a common cross-reference when lower surge power is acceptable.
