Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMAJ11A is a transient voltage suppressor (TVS) diode manufactured by Microsemi (now part of Microchip Technology). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Peak Pulse Power (PPP):** 400W (10/1000µs waveform)  
- **Standoff Voltage (VWM):** 11V  
- **Breakdown Voltage (VBR):** 12.2V (min), 13.5V (max) at IT = 1mA  
- **Clamping Voltage (VC):** 19.9V at IPP = 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, including ESD, lightning, and inductive switching.  
- Bidirectional configuration (clamps 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.  

This information is sourced from Microsemi's official datasheets.

Application Scenarios & Design Considerations

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS

Alternative Part Number

  • P4SMAJ11A --: Same SMA package unidirectional 400W TVS with 11V standoff voltage, direct electrical equivalent from a major supplier.
  • SMAJ11A-E3/61 --: Vishay's SMAJ series 400W TVS diode with matching 11V working voltage and SMA footprint, widely available and reliable.
  • 1SMA11AT3G --: 400W unidirectional TVS in SMA package with 11V standoff, suitable drop-in replacement with similar clamping characteristics.
  • P4SMA11A --: Same SMA package, 400W peak pulse power, 11V standoff unidirectional TVS; direct functional equivalent from the same vendor.
  • SMAJ11A-TR --: ST SMAJ 400W 11V unidirectional TVS in SMA package; matches clamping voltage and surge rating for drop-in replacement.
  • SMBJ11A --: 600W SMB unidirectional TVS with the same 11V standoff voltage; higher surge rating and a different package/series, widely available.
