Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The **SMAJ64CA** is a **Transient Voltage Suppressor (TVS) Diode** manufactured by **Microsemi**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Voltage - Reverse Standoff (V_RWM):** 64V  
- **Voltage - Breakdown (V_BR):** 71.2V (min)  
- **Voltage - Clamping (V_C):** 103V @ 16.7A (I_PP)  
- **Peak Pulse Current (I_PP):** 16.7A (8/20μs waveform)  
- **Power - Peak Pulse (P_PP):** 1717W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package / Case:** DO-214AC (SMA)  
- **Mounting Type:** Surface Mount  
- **Polarity:** Bidirectional  

### **Descriptions:**
- Designed for **transient voltage suppression** in sensitive electronics.  
- Protects circuits from **ESD, lightning, and other voltage transients**.  
- **Bidirectional** operation allows clamping of both positive and negative voltage spikes.  
- **Low leakage current** in standby mode.  

### **Features:**
- **Fast response time** (typically <1ns).  
- **High surge capability**.  
- **RoHS compliant**.  
- **AEC-Q101 qualified** for automotive applications.  
- **Reliable performance** in harsh environments.  

This TVS diode is commonly used in **telecommunications, automotive, industrial, and consumer electronics** for overvoltage protection.

Application Scenarios & Design Considerations

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS

Alternative Part Number

  • SMBJ64CA --: Same 64V bidirectional TVS diode in a larger SMB package, offering higher surge rating and a different series name for easy distinction.
  • P6SMB68CA --: Bidirectional TVS with a close standoff voltage (68V) in SMB package, suitable as a functional replacement with a different series prefix.
  • 1.5SMC68CA --: Bidirectional 1500W TVS diode with 68V standoff in SMC package, providing comparable clamping performance under a clearly different part series.
  • 1SMB64CAT3G --: SMB bidirectional TVS diode with matching 64V standoff and comparable peak pulse power, suitable drop-in replacement.
  • 1SMB64CA --: Bidirectional 600W SMB TVS with 64V standoff, same package and clamping characteristics, suitable alternative.
  • 1KSMB64CA --: Bidirectional TVS diode with matching 64V standoff in SMB package, suitable as a functional replacement with similar clamping characteristics.
