Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMAJ18A is a Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Part Number:** SMAJ18A  
- **Manufacturer:** Littelfuse  
- **Type:** Uni-directional TVS Diode  
- **Peak Pulse Power:** 400W (10/1000μs waveform)  
- **Breakdown Voltage (VBR):** 20.0V (min) – 22.2V (max)  
- **Standoff Voltage (VRWM):** 18V  
- **Clamping Voltage (VC):** 29.2V at 1A  
- **Peak Pulse Current (IPP):** 13.7A  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** SMA (DO-214AC)  

### **Descriptions:**  
- Designed to protect sensitive electronics from voltage transients and surges.  
- Provides high surge capability for robust circuit protection.  
- Suitable for applications requiring fast response to transient overvoltage events.  

### **Features:**  
- **Low Clamping Voltage:** Ensures effective protection for sensitive components.  
- **Fast Response Time:** Typically less than 1ps.  
- **High Surge Capability:** Withstands repetitive transients.  
- **RoHS Compliant:** Meets environmental standards.  
- **Agency Approvals:** UL Recognized, IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge) compliant.  

This information is based solely on Littelfuse's datasheet for the SMAJ18A TVS diode.

Application Scenarios & Design Considerations

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS

Alternative Part Number

  • P4SMA18A --: Same SMA package, 400W unidirectional TVS with 18V standoff, direct functional equivalent.
  • SMBJ18A --: SMB package 600W unidirectional TVS at 18V standoff; higher surge rating and widely available drop-in upgrade.
  • 1SMA18AT3G --: SMA package 400W unidirectional TVS with 18V standoff, same electrical role from a major alternate source.
  • TPSMA18A --: SMA-packaged 18V unidirectional TVS with equivalent electrical characteristics and good availability.
  • SMA6J18A --: 18V unidirectional TVS in SMA package with 600W rating; different series name and manufacturer, suitable when higher surge capability is acceptable.
