Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMAJ54CA is a bidirectional TVS (Transient Voltage Suppressor) diode manufactured by Fairchild Semiconductor (now part of ON Semiconductor).  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 54V  
- **Voltage - Breakdown (V_BR):** 60V (min)  
- **Voltage - Clamping (V_CL):** 87.4V at 10A (I_PP)  
- **Peak Pulse Current (I_PP):** 10A (8/20μs waveform)  
- **Power - Peak Pulse (P_PP):** 600W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AC (SMA)  

### **Descriptions and Features:**  
- **Bidirectional Protection:** Protects against both positive and negative transient voltages.  
- **Low Clamping Voltage:** Provides effective suppression of high-energy transients.  
- **Fast Response Time:** Responds quickly to transient events (typically <1ps).  
- **High Surge Capability:** Handles high peak pulse currents.  
- **RoHS Compliant:** Environmentally friendly, lead-free component.  

This TVS diode is commonly used for ESD (Electrostatic Discharge) and surge protection in applications such as power supplies, communication systems, and automotive electronics.

Application Scenarios & Design Considerations

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS

Alternative Part Number

  • SMBJ54CA --: Same 54V bidirectional TVS diode in a larger SMB package, offering higher surge power capability and widely available as a drop-in functional replacement.
  • P6SMB54CA --: 600W bidirectional transient voltage suppressor with matching 54V standoff voltage, suitable when higher peak pulse power is acceptable.
  • 1.5SMC54CA --: 1500W bidirectional TVS diode with the same 54V working voltage, providing a robust alternative for higher energy surge protection needs.
  • 1SMB54CAT3G --: Bidirectional 54V TVS in SMB package with comparable power handling, widely available and electrically compatible.
