Description and Introduction

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR The SMDJ70CA is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by LITTELFUSE.  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 70V  
- **Voltage - Breakdown (V_BR):** 77.8V (Min)  
- **Voltage - Clamping (V_C):** 112V (Max) at 47.1A  
- **Peak Pulse Current (I_PP):** 47.1A (8/20µs)  
- **Power - Peak Pulse (P_PP):** 600W (10/1000µs)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Descriptions:**  
- Designed for high-speed overvoltage protection in sensitive electronics.  
- Bidirectional TVS diode for AC or DC circuits.  
- Low clamping voltage for effective transient suppression.  

### **Features:**  
- **High Surge Capability:** Handles large transient currents.  
- **Fast Response Time:** Reacts quickly to voltage spikes.  
- **RoHS Compliant:** Meets environmental standards.  
- **Automotive Grade:** Suitable for automotive applications.

Application Scenarios & Design Considerations

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR

Alternative Part Number

  • 5.0SMDJ70CA --: Same manufacturer and same 70V bidirectional TVS family, but the 5.0SMDJ series offers higher peak pulse power (5000W vs 3000W) and is a drop-in upgrade in the same SMC package.
  • SMCJ70CA --: Same SMC package and 70V bidirectional clamping voltage, lower 1500W rating but widely available and electrically compatible for lower-surge applications.
  • SMDJ70CA-T7 --: Bourns equivalent 3000W bidirectional TVS in SMC with matching 70V standoff voltage, suitable as a cross-manufacturer replacement.
  • 1.5SMC70CA --: 1500W bidirectional 70V TVS in SMC outline, offering a cost-effective alternative when full 3000W surge performance is not required.
