Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The **SMAJ16A** is a **transient voltage suppressor (TVS) diode** manufactured by **Fairchild Semiconductor** (now part of **ON Semiconductor**). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Part Number:** SMAJ16A  
- **Manufacturer:** Fairchild Semiconductor (now ON Semiconductor)  
- **Type:** Uni-directional TVS Diode  
- **Peak Pulse Power (PPP):** 400W (10/1000μs waveform)  
- **Standoff Voltage (VWM):** 16V  
- **Breakdown Voltage (VBR):** 17.8V (min) – 19.7V (max)  
- **Clamping Voltage (VC):** 25.7V at 1A (IPP)  
- **Peak Pulse Current (IPP):** 15.6A (8/20μs waveform)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** SMA (DO-214AC)  

### **Descriptions:**  
- Designed to protect sensitive electronics from voltage transients and surges.  
- Provides **ESD protection** and **lightning surge suppression**.  
- **Uni-directional** (polarized) operation for positive voltage transients.  

### **Features:**  
- **Low clamping voltage** for effective transient suppression.  
- **Fast response time** (typically <1ns).  
- **RoHS compliant** (lead-free).  
- **High surge capability** for robust protection.  
- **Reliable performance** in harsh environments.  

This diode is commonly used in **power supplies, communication systems, automotive electronics, and industrial applications** for transient protection.

Application Scenarios & Design Considerations

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS

Alternative Part Number

  • P4SMA16A --: Same SMA package unidirectional TVS with 16V standoff voltage and comparable clamping, direct functional drop-in replacement.
  • SMBJ16A --: Unidirectional 16V standoff TVS with similar surge rating; SMB package is slightly larger but electrically compatible and widely available.
  • 1SMA16AT3G --: SMA-packaged 16V unidirectional TVS diode with equivalent clamping characteristics, suitable alternative from a different series.
  • TPSMA16A --: SMA-package 16V unidirectional TVS diode offering equivalent standoff and clamping characteristics as a direct functional substitute.
  • SMAJ16A-E3/61 --: Equivalent 400W SMA unidirectional TVS diode with matching 16V standoff voltage and clamping characteristics.
  • SMAJ16A-TR --: Pin-compatible 400W SMA TVS diode with identical 16V working voltage, suitable alternative from a major supplier.
