Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMAJ130A is a transient voltage suppressor (TVS) diode manufactured by Fairchild Semiconductor (now part of ON Semiconductor). Below are its key specifications, descriptions, and features based on available data:  

### **Specifications:**  
- **Part Number:** SMAJ130A  
- **Manufacturer:** Fairchild Semiconductor (now ON Semiconductor)  
- **Type:** Unidirectional TVS Diode  
- **Peak Pulse Power (PPP):** 400W (10/1000µs waveform)  
- **Breakdown Voltage (VBR):** 143V (min) – 158V (max)  
- **Standoff Voltage (VRWM):** 130V  
- **Clamping Voltage (VC):** 208V (max) at Ipp = 1A  
- **Peak Pulse Current (IPP):** 1.93A (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 electrostatic discharge (ESD).  
- Unidirectional polarity means it clamps positive voltage spikes only.  
- Low incremental surge resistance for effective clamping.  

### **Features:**  
- **Fast Response Time:** Typically less than 1ps.  
- **High Surge Capability:** Handles high transient energy.  
- **RoHS Compliant:** Lead-free and environmentally friendly.  
- **Low Leakage Current:** Ensures minimal power loss in standby mode.  

This diode is commonly used in power supplies, communication systems, and industrial applications for overvoltage protection.  

(Note: Always refer to the latest datasheet for updated specifications.)

Application Scenarios & Design Considerations

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS

Alternative Part Number

  • P6SMB130A --: Same 130V standoff unidirectional TVS in SMB package with comparable clamping and power rating, widely available and pin-compatible.
  • SMBJ130A --: Direct SMB-package 130V unidirectional TVS with similar surge capability; different series naming makes it easy to distinguish from the source.
  • 1SMB130AT3G --: SMB 130V unidirectional TVS diode with equivalent standoff voltage and power handling, suitable drop-in replacement.
  • SMAJ130A-E3/61 --: Same SMAJ series TVS diode with identical 130V standoff voltage and 400W peak pulse power, supplied in the E3/61 packaging variant.
  • P4SMA130A --: Equivalent 400W unidirectional TVS diode in SMA package with 130V standoff voltage, suitable drop-in replacement from a different manufacturer.
  • SMAJ130A-TR --: Same 400W SMA TVS diode rating with 130V standoff voltage, offering a cross-manufacturer alternative with similar electrical characteristics.
  • P6SMB150A --: SMB-packaged unidirectional TVS diode with a comparable standoff voltage and clamping performance, widely available and a common drop-in substitute for SMAJ130A.
