Description and Introduction

TRANSIL The SMAJ15A-TR is a surface-mount transient voltage suppressor (TVS) diode manufactured by STMicroelectronics (ST).  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 15V  
- **Voltage - Breakdown (V_BR):** 16.7V (min)  
- **Voltage - Clamping (V_C):** 24.4V at 1A  
- **Peak Pulse Current (I_PP):** 1A (8/20μs pulse)  
- **Power - Peak Pulse (P_PP):** 400W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AC (SMA)  
- **Mounting Type:** Surface Mount  
- **RoHS Compliant:** Yes  

### **Descriptions:**  
The SMAJ15A-TR is designed to protect sensitive electronics from voltage transients, including electrostatic discharge (ESD), inductive load switching, and lightning-induced surges. It offers fast response times and low clamping voltage.  

### **Features:**  
- **Low Clamping Voltage:** Ensures effective protection for sensitive components.  
- **High Surge Capability:** Handles high transient currents.  
- **Fast Response Time:** Reacts quickly to transient events.  
- **Surface-Mount Package:** Suitable for automated assembly processes.  
- **RoHS Compliant:** Meets environmental standards.  

This diode is commonly used in telecommunications, automotive, and industrial applications for circuit protection.
