Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMBJ8.0A is a transient voltage suppressor (TVS) diode manufactured by **FAIRCHILD**. Below are its specifications, descriptions, and features based on factual data:  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 8.0V  
- **Voltage - Breakdown (V_BR):** 8.9V (Min)  
- **Voltage - Clamping (V_C):** 12.9V at 1A  
- **Peak Pulse Current (I_PP):** 1A (8/20µs)  
- **Power - Peak Pulse (P_PP):** 600W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** SMB (DO-214AA)  
- **Polarity:** Unidirectional  

### **Descriptions:**  
- The **SMBJ8.0A** is designed to protect sensitive electronics from voltage transients, including ESD, lightning, and inductive switching.  
- It is a **unidirectional** TVS diode, meaning it clamps positive transients only.  
- The diode is **RoHS compliant** and **halogen-free**.  

### **Features:**  
- **Low Clamping Voltage** for effective transient suppression.  
- **Fast Response Time** (typically <1ps).  
- **High Surge Capability** (600W peak pulse power).  
- **SMB Package** for space-saving PCB mounting.  
- **Reliable Protection** against ESD, lightning, and other transient events.  

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

  • P6SMB8.0A --: Same SMB package unidirectional TVS with 8.0V standoff and 600W peak pulse rating, widely available and drop-in compatible.
  • 1SMB8.0AT3G --: SMB-packaged 8.0V unidirectional TVS diode with 600W surge capability, a common cross for SMBJ8.0A.
  • SMAJ8.0A --: Similar 8.0V unidirectional TVS in SMA package; lower 400W rating but usable where surge requirements are relaxed and board space allows SMA footprint.
