Description and Introduction

TRANSIL The **SMAJ28A-TR** is a **transient voltage suppressor (TVS) diode** manufactured by **STMicroelectronics (ST)**.  

### **Specifications:**  
- **Voltage - Reverse Standoff (Vrwm):** 28V  
- **Voltage - Breakdown (Vbr):** 31.1V (min) to 34.4V (max)  
- **Voltage - Clamping (Vc):** 45.4V at 1A  
- **Peak Pulse Current (Ipp):** 24.2A (8/20μs pulse)  
- **Power - Peak Pulse (Ppp):** 1100W (10/1000μs pulse)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** **DO-214AC (SMA)**  
- **Mounting Type:** Surface Mount  
- **Polarity:** Unidirectional  

### **Descriptions & Features:**  
- Designed to protect sensitive electronics from **transient voltage spikes** (ESD, lightning, inductive switching).  
- **Low clamping voltage** for effective overvoltage protection.  
- **Fast response time** (typically <1ns).  
- **High surge capability** for robust protection.  
- **RoHS compliant** and halogen-free.  
- **Unidirectional TVS diode** (conducts in one direction only).  

This component is commonly used in **power supplies, communication systems, automotive electronics, and industrial applications** for transient suppression.
