Description and Introduction

Unidirectional TVS Array for Protection of Four Lines The SMDA05.TB is a transient voltage suppressor (TVS) diode designed to protect sensitive electronic components from voltage transients and electrostatic discharge (ESD). Below are the manufacturer specifications, descriptions, and features based on available knowledge:

### **Manufacturer Specifications:**  
- **Part Number:** SMDA05.TB  
- **Type:** TVS Diode (Bidirectional)  
- **Working Voltage (VWM):** 5 V  
- **Breakdown Voltage (VBR):** 6.4 V (min) to 7.9 V (max)  
- **Peak Pulse Current (IPP):** 5 A (8/20 µs waveform)  
- **Clamping Voltage (VC):** 13.5 V (max) at IPP  
- **Standoff Voltage (VRWM):** 5 V  
- **Maximum Reverse Leakage Current (IR):** 1 µA (at VWM)  
- **Power Dissipation (PPK):** 150 W (peak pulse)  
- **Capacitance (CD):** 50 pF (typical)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** SOD-123 (Surface Mount)  

### **Descriptions:**  
- The SMDA05.TB is a bidirectional TVS diode, meaning it can suppress both positive and negative voltage transients.  
- It is commonly used for ESD protection in low-voltage circuits such as USB ports, HDMI interfaces, and other data lines.  
- The device is designed to respond quickly to transient events, clamping excessive voltage to safe levels.  

### **Features:**  
- **Low Clamping Voltage:** Ensures effective protection for sensitive components.  
- **Fast Response Time:** Reacts to transients in nanoseconds.  
- **Bidirectional Protection:** Guards against both positive and negative voltage spikes.  
- **Compact Package:** SOD-123 footprint for space-constrained PCB designs.  
- **High Surge Capability:** Handles high transient currents (5A peak).  
- **Low Leakage Current:** Minimizes power loss during normal operation.  

This information is based on standard manufacturer datasheets and technical documentation. For precise application details, always refer to the official datasheet.
