Description and Introduction

TECHNICAL SPECIFICATIONS OF SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR The SMBJ64A is a transient voltage suppressor (TVS) diode manufactured by MICROSEMI. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Voltage - Reverse Standoff (VRWM):** 64V  
- **Voltage - Breakdown (VBR):** 71.2V (Min), 78.8V (Max)  
- **Voltage - Clamping (VC):** 103V at 10A (IPP)  
- **Peak Pulse Current (IPP):** 10A (8/20µs)  
- **Power - Peak Pulse (PPP):** 600W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** SMB (DO-214AA)  

### **Descriptions:**  
- The SMBJ64A is designed to protect sensitive electronics from high-voltage transients, such as ESD, lightning, and inductive load switching.  
- It is a bidirectional TVS diode, meaning it can suppress both positive and negative voltage spikes.  
- The device meets the requirements of various industry standards for surge protection.  

### **Features:**  
- **Low Clamping Voltage:** Provides effective protection for sensitive components.  
- **High Surge Capability:** Can handle large transient currents.  
- **Fast Response Time:** Reacts quickly to transient events (typically in picoseconds).  
- **RoHS Compliant:** Meets environmental standards.  
- **Bidirectional Operation:** Protects against voltage spikes in both polarities.  

This information is based on MICROSEMI's official datasheet for the SMBJ64A TVS diode.

Application Scenarios & Design Considerations

Alternative Part Number

  • P6SMB68A --: Same SMB (DO-214AA) package unidirectional TVS with a close standoff voltage (58.1V vs 64V) and comparable 600W peak pulse rating, widely available from a major TVS supplier.
  • 1SMB64AT3G --: SMB-packaged 600W unidirectional TVS diode with matching 64V standoff voltage, direct functional equivalent from a well-established manufacturer.
  • SMAJ64A --: Same 64V standoff unidirectional TVS in the smaller SMA (DO-214AC) package; usable where board space is tight and 400W peak pulse power is sufficient.
