Description and Introduction

Zener TVSs The SMCJ54CA is a bidirectional transient voltage suppressor (TVS) diode manufactured by Fairchild Semiconductor (now part of ON Semiconductor).  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 54V  
- **Voltage - Breakdown (V_BR):** 60V (min)  
- **Peak Pulse Power (P_PPM):** 1500W (10/1000μs)  
- **Clamping Voltage (V_C):** 87.1V (at 10A)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Descriptions:**  
- Designed to protect sensitive electronics from voltage transients and ESD events.  
- Bidirectional configuration allows clamping of both positive and negative voltage spikes.  
- Low incremental surge resistance for effective clamping.  

### **Features:**  
- High surge capability (1500W peak pulse power).  
- Fast response time (typically <1ps).  
- RoHS compliant.  
- Low leakage current.  

This device is commonly used in power supplies, communication systems, and automotive applications for transient voltage suppression.  

(Note: Fairchild Semiconductor is now part of ON Semiconductor, and product availability may vary.)

Application Scenarios & Design Considerations

Zener TVSs

Alternative Part Number

  • 1.5SMC54CA --: Same 1500W bidirectional TVS class with 54V standoff, widely available and electrically equivalent for most clamping applications.
  • P6SMB54CA --: 600W bidirectional TVS with matching 54V standoff voltage; suitable when lower surge rating is acceptable and a smaller package is preferred.
  • SMAJ54CA --: 400W bidirectional TVS in SMA with 54V standoff; a compact lower-power alternative for space-constrained designs with reduced surge requirements.
