Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMAJ40A is a unidirectional TVS (Transient Voltage Suppressor) diode manufactured by CONCORD.  

### **Specifications:**  
- **Voltage - Reverse Standoff (VRWM):** 40V  
- **Voltage - Breakdown (VBR):** 44.4V (min)  
- **Voltage - Clamping (VC):** 64.5V at 10A (IPP)  
- **Peak Pulse Current (IPP):** 10A (8/20µs)  
- **Power - Peak Pulse (PPP):** 400W  
- **Package:** SMA (DO-214AC)  
- **Operating Temperature Range:** -55°C to +150°C  

### **Descriptions:**  
The SMAJ40A is designed to protect sensitive electronics from voltage transients, such as ESD (Electrostatic Discharge), lightning, and inductive load switching. It provides fast response to transient overvoltage events.  

### **Features:**  
- Low clamping voltage  
- Fast response time  
- High surge capability  
- RoHS compliant  
- Unidirectional polarity  

This information is based on the manufacturer's datasheet. For detailed performance characteristics, refer to the official CONCORD documentation.

Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMAJ40A is a transient voltage suppressor (TVS) diode manufactured by Fairchild Semiconductor (now part of ON Semiconductor). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Peak Pulse Power (PPP):** 400W (8/20μs waveform)  
- **Standoff Voltage (VWM):** 40V  
- **Breakdown Voltage (VBR):** 44.4V (min), 49.2V (max)  
- **Clamping Voltage (VC):** 64.5V at 1A (IPP)  
- **Maximum Reverse Leakage Current (IRM):** 1μA at VWM  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AC (SMA)  

### **Descriptions:**  
- The SMAJ40A is designed to protect sensitive electronics from voltage transients, including ESD, lightning, and inductive load switching.  
- It is a unidirectional TVS diode, meaning it clamps positive voltage spikes.  
- It meets IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge) standards.  

### **Features:**  
- Low incremental surge resistance for effective clamping.  
- Fast response time (<1ps).  
- RoHS compliant.  
- High reliability and surge capability.  

This information is strictly factual from the manufacturer's datasheet. No additional recommendations are provided.
