Description and Introduction

TECHNICAL SPECIFICATIONS OF SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR The SMCJ75A is a transient voltage suppressor (TVS) diode manufactured by **Fairchild Semiconductor**. Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Voltage Rating (Vrwm):** 75V  
- **Breakdown Voltage (Vbr):** 83.3V (min), 92.4V (max)  
- **Peak Pulse Power (Pppm):** 1500W (10/1000μs waveform)  
- **Maximum Clamping Voltage (Vc):** 121V at 10A  
- **Peak Pulse Current (Ipp):** 12.4A  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Descriptions:**  
- Designed to protect sensitive electronics from high-voltage transients.  
- Bi-directional TVS diode (clamps both positive and negative surges).  
- Low incremental surge resistance for effective clamping.  

### **Features:**  
- **High Power Handling:** 1500W peak pulse power capability.  
- **Fast Response Time:** Reacts quickly to transient events (picosecond range).  
- **RoHS Compliant:** Meets environmental standards.  
- **Reliable Protection:** Safeguards circuits against ESD, lightning, and other transients.

Application Scenarios & Design Considerations

Alternative Part Number

  • 1SMC75AT3G --: Same 1500W unidirectional TVS class with 75V standoff voltage, from the successor of Fairchild's discrete portfolio, so electrical behavior and package are directly compatible.
  • P6SMB75A --: 600W SMB TVS with matching 75V standoff and unidirectional clamping, suitable when lower surge rating is acceptable and a different series naming is preferred.
  • SMAJ75A --: 400W SMA TVS with the same 75V standoff voltage and unidirectional configuration, a good drop-in for space-constrained or lower-energy clamping needs.
  • 1.5SMC75A --: Same 1500W peak pulse power, 75V standoff unidirectional TVS in the SMC (DO-214AB) package, directly interchangeable with equivalent or better clamping performance.
