Description and Introduction

TRANSIL The SMCJ30A-TR is a surface-mount transient voltage suppressor (TVS) diode manufactured by STMicroelectronics.  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 30V  
- **Voltage - Breakdown (V_BR):** 33.3V (min)  
- **Voltage - Clamping (V_CL):** 48.4V at 10A  
- **Peak Pulse Current (I_PP):** 10A (8/20µs)  
- **Power - Peak Pulse (P_PP):** 600W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  
- **Mounting Type:** Surface Mount  

### **Descriptions and Features:**  
- Designed to protect sensitive electronics from high-voltage transients.  
- Low clamping voltage for effective protection.  
- Fast response time to transient events.  
- RoHS compliant and halogen-free.  
- Suitable for applications like power supplies, data lines, and telecommunications.  

For detailed electrical characteristics, refer to the official ST datasheet.

Application Scenarios & Design Considerations

Alternative Part Number

  • 1SMC30AT3G --: Same 1500W unidirectional TVS diode with 30V standoff voltage in SMC package, direct functional equivalent.
  • SMDJ30A --: 3000W SMC TVS diode with 30V standoff, higher surge rating but same footprint and clamping behavior.
  • P6SMB30A --: 600W SMB TVS diode with 30V standoff, lower power rating but suitable for lower-surge applications and smaller package.
