Description and Introduction

400W SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR The **SMAJ51A-13-F** is a **Transient Voltage Suppressor (TVS) Diode** manufactured by **DIODES Incorporated**.  

### **Specifications:**  
- **Voltage - Reverse Standoff (Vrwm):** 51V  
- **Voltage - Breakdown (Vbr):** 56.7V (Min)  
- **Voltage - Clamping (Vc):** 82.1V at 10A (Typ)  
- **Peak Pulse Current (Ipp):** 10A (8/20µs)  
- **Power - Peak Pulse (Ppp):** 400W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package/Case:** SMA (DO-214AC)  
- **Mounting Type:** Surface Mount  
- **Polarity:** Unidirectional  

### **Descriptions:**  
- Designed for **ESD and surge protection** in sensitive electronics.  
- Provides **high surge capability** for transient voltage suppression.  
- **Low clamping voltage** for effective circuit protection.  

### **Features:**  
- **Fast response time** (typically <1ps).  
- **High reliability** and **low leakage current**.  
- **RoHS compliant** and **halogen-free**.  
- **Unidirectional** for protection against positive transients.  

This TVS diode is commonly used in **telecommunications, automotive, and industrial applications** for protecting circuits from voltage spikes and transients.
