Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMAJ8.0A is a transient voltage suppressor (TVS) diode manufactured by Microsemi. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Voltage - Reverse Standoff (Vrwm):** 8.0V  
- **Voltage - Breakdown (Vbr):** 8.9V (min) @ 1mA  
- **Voltage - Clamping (Vc):** 12.9V @ 5A  
- **Peak Pulse Current (Ipp):** 5A (8/20µs)  
- **Power - Peak Pulse (Pppm):** 400W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** SMA (DO-214AC)  

### **Descriptions:**
- The SMAJ8.0A is designed to protect sensitive electronics from voltage transients and surges.  
- It provides unidirectional protection, meaning it clamps positive voltage spikes.  
- Compliant with RoHS standards.  

### **Features:**
- Low clamping voltage for effective transient suppression.  
- Fast response time (typically <1ps).  
- High surge capability.  
- Suitable for applications requiring ESD, lightning, and inductive load protection.  

For detailed datasheet information, refer to Microsemi’s official documentation.

Application Scenarios & Design Considerations

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS

Alternative Part Number

  • P6SMBJ8.0A --: Same 8.0V standoff unidirectional TVS in a comparable SMB package with similar clamping voltage and peak pulse power, widely available from a major TVS supplier.
  • SMBJ8.0A --: Industry-standard 8.0V unidirectional SMB TVS with equivalent 600W peak pulse rating and similar breakdown/clamping characteristics, easy drop-in replacement.
  • TPSMBJ8.0A --: Automotive-grade 8.0V unidirectional SMB TVS offering comparable surge capability and clamping performance, suitable when higher reliability or AEC-Q101 qualification is desired.
  • P6SMB10A --: Same manufacturer, similar SMB package unidirectional TVS with 10V standoff that safely covers the 8V working voltage and provides comparable surge protection.
  • 1SMB8.0AT3G --: SMB-packaged unidirectional TVS with matching 8.0V standoff and 400W surge capability, offering a distinct part series as a cross-vendor alternative.
  • P6SMB8.0A --: Same 8.0V standoff unidirectional TVS in a comparable SMB package with similar clamping performance, widely available from a major supplier.
  • TPSMB8.0A --: Automotive-grade 8.0V unidirectional TVS in SMB with equivalent standoff voltage and clamping characteristics, suitable drop-in replacement.
  • TPSMB10A --: Automotive-grade SMB unidirectional TVS with similar clamping and 600W pulse rating, offering higher reliability for the same circuit position.
  • 1SMB10AT3G --: SMB-packaged unidirectional TVS with similar clamping and surge capability, offering a distinct series name and good second-source availability.
