Description and Introduction

Zener TVSs The SMBJ75CA is a bidirectional TVS (Transient Voltage Suppressor) diode manufactured by FAIRCHILD. Below are its specifications, descriptions, and features based on available information:  

### **Specifications:**  
- **Voltage - Reverse Standoff (VRWM):** 75V  
- **Voltage - Breakdown (VBR):** 83.3V (min)  
- **Voltage - Clamping (VC):** 121V at 10A (IPP)  
- **Peak Pulse Current (IPP):** 10A (8/20µs)  
- **Power - Peak Pulse (PPP):** 600W  
- **Operating Temperature:** -55°C to +150°C  
- **Package:** SMB (DO-214AA)  

### **Descriptions:**  
- Designed to protect sensitive electronics from voltage transients and ESD (Electrostatic Discharge).  
- Bidirectional polarity, meaning it can suppress both positive and negative voltage spikes.  
- RoHS compliant.  

### **Features:**  
- Low clamping voltage.  
- Fast response time.  
- High surge capability.  
- Meets IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge) standards.  

For exact application details, refer to the official datasheet from FAIRCHILD.

Application Scenarios & Design Considerations

Zener TVSs

Alternative Part Number

  • P6SMB75CA --: Same SMB package bidirectional 75V TVS diode with comparable clamping voltage and peak pulse power, direct functional drop-in from a different series.
  • 1SMB75CAT3G --: Bidirectional 75V TVS in SMB footprint with similar surge rating, widely available and electrically compatible.
  • SMAJ75CA --: Bidirectional 75V TVS with matching standoff voltage; SMA package is smaller than SMB so verify power dissipation, but it is a common lower-cost alternative.
