Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMAJ110A is a transient voltage suppressor (TVS) diode manufactured by **FAIRCHILD**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Voltage - Reverse Standoff (V₃₀):** 110V  
- **Voltage - Breakdown (Min):** 122V  
- **Voltage - Clamping (Max) @ Iₚₚ:** 176V at 10A  
- **Peak Pulse Current (Iₚₚ):** 10A (8/20µs waveform)  
- **Power - Peak Pulse (Pₚₚ):** 400W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package / Case:** DO-214AC (SMA)  

### **Descriptions:**
- 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.  

### **Features:**
- **Fast Response Time:** Typically less than 1ps.  
- **High Surge Capability:** Handles high transient currents.  
- **Low Leakage Current:** Ensures minimal power loss during normal operation.  
- **RoHS Compliant:** Meets environmental standards.  

This diode is commonly used in **telecommunications, automotive, and industrial applications** for ESD and surge protection.

Application Scenarios & Design Considerations

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS

Alternative Part Number

  • SMBJ110A --: Same 110V standoff unidirectional TVS diode in a larger SMB package, offering higher surge rating and widely available as a drop-in functional replacement.
  • P6SMB110A --: 600W unidirectional TVS with 110V standoff in SMB package, similar clamping characteristics and a common cross-reference for SMAJ110A.
  • 1.5SMC110A --: 1500W unidirectional TVS diode with 110V standoff, higher power handling in SMC package, suitable when extra surge margin is acceptable.
  • 1SMB110AT3G --: SMB-packaged 110V unidirectional transient voltage suppressor with equivalent electrical characteristics and strong availability.
