Description and Introduction

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR The SMDJ78CA is a Transient Voltage Suppressor (TVS) Diode manufactured by LITTELFUSE.  

### **Specifications:**  
- **Part Number:** SMDJ78CA  
- **Manufacturer:** LITTELFUSE  
- **Type:** Bidirectional TVS Diode  
- **Peak Pulse Power (10/1000μs):** 1500W  
- **Breakdown Voltage (VBR):** 86.5V (Min), 95.8V (Max)  
- **Standoff Voltage (VRWM):** 78V  
- **Clamping Voltage (VC):** 125V at 10A  
- **Maximum Reverse Leakage Current (IR):** 1μA at VRWM  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Descriptions and Features:**  
- Designed to protect sensitive electronics from voltage transients and surges.  
- Bidirectional configuration for clamping both positive and negative transients.  
- Low incremental surge resistance for effective clamping.  
- RoHS compliant and halogen-free.  
- Suitable for high-speed data line protection, power supplies, and industrial applications.  

For detailed technical information, refer to the official LITTELFUSE datasheet.

Application Scenarios & Design Considerations

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR

Alternative Part Number

  • 5.0SMDJ78CA --: Same 78V bidirectional TVS in the 5.0SMDJ series with higher 5000W peak pulse rating, drop-in SMC footprint and widely available.
  • SMCJ78CA --: 1500W bidirectional TVS with identical 78V standoff voltage in an SMC package, suitable when lower surge rating is acceptable.
  • 1.5SMC78CA --: 1500W bidirectional transient voltage suppressor with matching 78V working voltage and SMC outline, a common cross-reference for SMDJ78CA.
  • SMDJ78A --: Unidirectional 78V TVS from the same SMDJ family with identical 3000W rating and package; usable if the application can tolerate unidirectional clamping instead of bidirectional.
