Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMAJ30A is a transient voltage suppressor (TVS) diode manufactured by **FAIRCHILD**. 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):** 30V  
- **Breakdown Voltage (VBR):** 33.3V (min), 36.8V (max)  
- **Clamping Voltage (VC):** 48.4V at 1A  
- **Maximum Reverse Leakage Current (IR):** 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 electrostatic discharge (ESD).  
- Bi-directional TVS diode for AC or DC circuits.  
- Low incremental surge resistance for effective clamping.  

### **Features:**  
- **Fast Response Time:** Typically less than 1ps.  
- **High Surge Capability:** Withstands high transient currents.  
- **RoHS Compliant:** Lead-free and environmentally friendly.  
- **Low Clamping Voltage:** Provides effective protection for downstream components.  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS

Alternative Part Number

  • P6SMB30A --: Same 30V standoff unidirectional TVS in SMB package with comparable clamping voltage and power rating, widely available from a major supplier.
  • SMBJ30A --: Direct SMB-package 30V unidirectional TVS with 600W peak pulse power, matching the SMAJ30A electrical role and footprint.
  • 1SMB30AT3G --: SMB 30V unidirectional TVS diode with similar surge capability, offered by a well-established manufacturer as a functional substitute.
  • SMAJ30A-E3/61 --: Same SMAJ series 30V unidirectional TVS with identical 400W peak pulse rating and SMA package, widely available from Vishay as a direct form-fit-function substitute.
  • P4SMA30A --: 400W unidirectional TVS diode in SMA package with 30V standoff voltage, matching the SMAJ30A electrical characteristics and footprint.
  • SMA6J30A --: 600W unidirectional TVS in SMA package with 30V standoff; higher surge rating provides extra margin while remaining pin-compatible with SMAJ30A.
