Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMAJ100A is a transient voltage suppressor (TVS) diode manufactured by Microsemi.  

### **Specifications:**  
- **Peak Pulse Power (PPP):** 400W (8/20μs waveform)  
- **Standoff Voltage (VWM):** 100V  
- **Breakdown Voltage (VBR):** 111V (min) – 123V (max)  
- **Clamping Voltage (VC):** 162V (max) at 1A  
- **Maximum Reverse Leakage Current (IRM):** 1μA at VWM  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AC (SMA)  

### **Descriptions and Features:**  
- Designed to protect sensitive electronics from voltage transients and surges.  
- Fast response time (typically <1ps).  
- Low incremental surge resistance.  
- RoHS compliant.  
- Bi-directional (available in both unidirectional and bidirectional versions).  
- Meets IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge) standards.  

This diode is commonly used in telecommunications, industrial controls, and power supply protection circuits.

Application Scenarios & Design Considerations

Alternative Part Number

  • P6SMB100A --: Same 100V standoff unidirectional TVS in SMB package with comparable clamping and power rating, widely available and pin-compatible.
  • SMBJ100A --: Direct SMB-package 100V unidirectional TVS with similar surge capability, a common cross for SMAJ series parts.
  • 1SMB100AT3G --: SMB 100V unidirectional TVS diode with equivalent standoff voltage and power handling, suitable drop-in replacement.
