Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMAJ7.0CA is a transient voltage suppressor (TVS) diode manufactured by Microsemi. Here are its specifications, descriptions, and features:

### **Specifications:**
- **Voltage - Reverse Standoff (V_RWM):** 7.0V  
- **Voltage - Breakdown (V_BR):** 7.78V (min)  
- **Voltage - Clamping (V_C) @ I_PP:** 12.1V (max) at 10A  
- **Current - Peak Pulse (I_PP):** 10A (8/20µs)  
- **Power - Peak Pulse (P_PP):** 400W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** SMA (DO-214AC)  

### **Descriptions:**
- **Type:** Bidirectional TVS Diode  
- **Application:** Protects sensitive electronics from voltage transients, ESD, and lightning-induced surges.  
- **Compliance:** RoHS compliant.  

### **Features:**
- **Low Clamping Voltage:** Provides effective protection for sensitive circuits.  
- **Fast Response Time:** Responds quickly to transient events (picosecond range).  
- **High Surge Capability:** Handles high peak pulse currents.  
- **Bidirectional Operation:** Protects against both positive and negative voltage transients.  
- **Reliable Performance:** Robust construction for industrial and automotive applications.  

This diode is commonly used in power supplies, communication systems, and consumer electronics for surge protection.

Application Scenarios & Design Considerations

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS

Alternative Part Number

  • P6SMB7.0CA --: Same 7.0V bidirectional TVS in a similar SMB package with comparable peak pulse power, widely available and a direct functional substitute.
  • SMBJ7.0CA --: Bidirectional 7.0V TVS diode in SMB package with matching standoff voltage and clamping characteristics, a common cross-reference for SMAJ series.
  • 1SMB7.0CA --: Bidirectional 7.0V SMB TVS diode with equivalent surge rating and electrical parameters, suitable drop-in replacement.
  • 1.5SMC7.0CA --: Higher 1500W peak pulse power bidirectional TVS with 7.0V standoff in SMC package, offering extra surge margin where board space allows.
