Description and Introduction

Unidirectional TVS Array for Protection of Four Lines The SMDA05TB is a transient voltage suppressor (TVS) diode manufactured by SEMTECH. Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Voltage - Reverse Standoff (V_RWM):** 5V  
- **Voltage - Breakdown (V_BR):** 6.4V (Min)  
- **Voltage - Clamping (V_C):** 14.5V (Max) at 1A  
- **Peak Pulse Current (I_PP):** 1A (8/20µs)  
- **Power - Peak Pulse (P_PP):** 14.5W  
- **Operating Temperature Range:** -55°C to +150°C  

### **Description:**
- The SMDA05TB is a unidirectional TVS diode designed to protect sensitive electronics from voltage transients and electrostatic discharge (ESD).  
- It is housed in a SOD-123 package, making it suitable for space-constrained applications.  

### **Features:**
- **Low Clamping Voltage:** Provides effective protection for sensitive components.  
- **Fast Response Time:** Reacts quickly to transient voltage spikes.  
- **Unidirectional Polarity:** Designed for DC circuits where the voltage polarity is known.  
- **Compact SOD-123 Package:** Ideal for high-density PCB layouts.  
- **RoHS Compliant:** Meets environmental standards.  

This information is based solely on SEMTECH's datasheet for the SMDA05TB.
