Description and Introduction

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR The SMDJ51CA is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by LITTELFUSE.  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 51V  
- **Voltage - Breakdown (V_BR):** 56.7V (Min)  
- **Voltage - Clamping (V_C):** 82.1V at 28.9A (Peak Pulse Current)  
- **Peak Pulse Current (I_PP):** 28.9A (8/20µs)  
- **Power - Peak Pulse (P_PP):** 600W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Descriptions and Features:**  
- **Bidirectional TVS Diode:** Protects against both positive and negative transient voltage spikes.  
- **High Surge Capability:** Designed to handle high transient currents.  
- **Low Clamping Voltage:** Provides effective protection for sensitive electronics.  
- **RoHS Compliant:** Meets environmental standards.  
- **Applications:** Used in surge protection for communication equipment, power supplies, and industrial electronics.

Application Scenarios & Design Considerations

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR

Alternative Part Number

  • 5.0SMDJ51CA --: Same 5000W bidirectional TVS in the 5.0SMDJ series with identical 51V standoff and SMC package, offering higher surge rating as a direct upgrade.
  • SMCJ51CA --: 1500W bidirectional TVS with the same 51V standoff voltage and SMC footprint, suitable when lower power rating is acceptable.
  • SMDJ51A --: Same SMDJ series 3000W SMC package and 51V standoff but unidirectional; usable if only unidirectional clamping is needed.
