Description and Introduction

Low Voltage Unit for Gigabit Ethernet protection The SLVU2.8-4A1 is a transient voltage suppressor (TVS) diode manufactured by STMicroelectronics (STM). Below are the factual details about the component:

### **Manufacturer:**  
STMicroelectronics (STM)  

### **Specifications:**  
- **Type:** Bidirectional TVS Diode  
- **Working Voltage (Vrwm):** 2.8 V  
- **Breakdown Voltage (Vbr):** 3.1 V (min), 3.5 V (typ), 3.9 V (max)  
- **Clamping Voltage (Vc):** 9.2 V (at 1 A)  
- **Peak Pulse Current (Ipp):** 4 A (8/20 µs pulse)  
- **Maximum Reverse Leakage Current (Ir):** 1 µA (at Vrwm)  
- **Capacitance (Ct):** 50 pF (typ)  
- **Package:** SOD-323 (SC-76)  

### **Descriptions:**  
- Designed for ESD (electrostatic discharge) and transient overvoltage protection.  
- Protects sensitive electronics from voltage spikes in applications such as USB, HDMI, and other high-speed data lines.  
- Bidirectional configuration allows protection against both positive and negative voltage transients.  

### **Features:**  
- Low clamping voltage for effective protection.  
- Fast response time (<1 ns).  
- RoHS compliant and halogen-free.  
- Suitable for high-speed data line protection (e.g., USB 2.0, HDMI).  

For additional details, refer to the official STMicroelectronics datasheet.
