Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMAJ64A is a Transient Voltage Suppressor (TVS) diode manufactured by Microsemi (now part of Microchip Technology). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Peak Pulse Power (PPP):** 400W (10/1000μs waveform)  
- **Breakdown Voltage (VBR):** 71.2V (min) to 78.8V (max) at IT = 1mA  
- **Standoff Voltage (VRWM):** 64V  
- **Maximum Clamping Voltage (VC):** 103.4V at IPP = 1A  
- **Peak Pulse Current (IPP):** 3.88A (8/20μs waveform)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AC (SMA)  

### **Descriptions:**  
- The SMAJ64A is a unidirectional TVS diode designed to protect sensitive electronics from voltage transients, including ESD, lightning, and inductive load switching.  
- It is part of the SMAJ series, which offers high surge capability in a compact SMA package.  

### **Features:**  
- **Low Clamping Voltage:** Provides effective protection for sensitive components.  
- **Fast Response Time:** Responds quickly to transient events (typically <1ps).  
- **High Surge Capability:** Can handle large transient currents.  
- **RoHS Compliant:** Meets environmental standards.  
- **Unidirectional Operation:** Protects against positive voltage transients only.  

For bidirectional protection, the equivalent part would be the **SMAJ64CA**.  

This information is based on Microsemi's datasheet and product documentation.
