Description and Introduction

5 Line Transient Voltage Suppressor Array The SMF05C is a transient voltage suppressor (TVS) diode array designed to protect sensitive electronics from electrostatic discharge (ESD), electrical fast transients (EFT), and lightning-induced surges. Below are the manufacturer specifications, descriptions, and features:

### **Manufacturer Specifications:**
- **Voltage Rating (Working Peak Reverse Voltage):** 5V  
- **Breakdown Voltage (Min):** 6.4V  
- **Breakdown Voltage (Max):** 7.5V  
- **Clamping Voltage (at 5A):** 9.2V  
- **Peak Pulse Current (8/20µs):** 5A  
- **ESD Protection (IEC 61000-4-2, Contact Discharge):** ±30kV  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package Type:** SOT-23-5  

### **Description:**
The SMF05C is a low-capacitance TVS diode array that provides robust protection for high-speed data lines, such as USB, HDMI, and Ethernet interfaces. It integrates multiple TVS diodes in a compact SOT-23-5 package, offering board space savings while ensuring reliable transient suppression.

### **Features:**
- **Low Clamping Voltage:** Ensures minimal voltage overshoot during transient events.  
- **Low Leakage Current:** Typically <1µA at working voltage.  
- **Fast Response Time:** Responds to transients in less than 1ns.  
- **Multi-Channel Protection:** Protects up to five lines in a single package.  
- **RoHS Compliant:** Meets environmental standards.  
- **IEC 61000-4-2 (ESD) Compliance:** Protects against ±30kV contact discharge.  

This information is based solely on the manufacturer's datasheet and product documentation.
