Description and Introduction

Silicon Avalanche Diodes - 400W Surface Mount Transient Voltage Supressors The SMAJ180A is a transient voltage suppressor (TVS) diode manufactured by FAIRCHILD. Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Peak Pulse Power (PPP):** 400W (8/20µs waveform)  
- **Standoff Voltage (VWM):** 180V  
- **Breakdown Voltage (VBR):** 200V (min), 222V (max)  
- **Clamping Voltage (VC):** 292V at 1A  
- **Maximum Reverse Leakage Current (IRM):** 1µA at VWM  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AC (SMA)  

### **Descriptions:**  
- Designed to protect sensitive electronics from voltage transients and surges.  
- Bi-directional (can suppress both positive and negative transients).  
- Low incremental surge resistance for effective clamping.  

### **Features:**  
- Fast response time (typically <1ps).  
- High surge capability.  
- RoHS compliant.  
- Meets IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge) standards.

Application Scenarios & Design Considerations

Silicon Avalanche Diodes - 400W Surface Mount Transient Voltage Supressors

Alternative Part Number

  • P6SMB200A --: SMB-packaged unidirectional TVS diode with comparable 200V standoff and 600W peak pulse rating, suitable drop-in for SMAJ180A in most clamping applications.
  • SMBJ180A --: Same SMB footprint and 180V standoff unidirectional TVS with 600W surge capability, direct functional equivalent from a different series.
  • 1SMB180AT3G --: SMB unidirectional TVS diode rated 180V standoff and 600W peak pulse power, widely available alternative with similar clamping characteristics.
  • 1SMB200AT3G --: SMB-package unidirectional TVS with matching working voltage and power rating, a common cross for SMAJ180A.
