Description and Introduction

TVS Diode Arrays - Surface Mount TVS Avalanche Diode Array The part **SP0505BAJT** is manufactured by **SP** (likely referring to **STMicroelectronics** or another semiconductor manufacturer, as "SP" is sometimes used as a prefix for their parts). Below are the factual details about this component:

### **Specifications:**
1. **Type:** TVS Diode (Transient Voltage Suppressor)  
2. **Configuration:** Bidirectional  
3. **Working Voltage (Vrwm):** 5V  
4. **Breakdown Voltage (Vbr):** Typically 6.4V (minimum)  
5. **Clamping Voltage (Vc):** ~9.2V at 1A (typical)  
6. **Peak Pulse Current (Ipp):** 5A (8/20μs waveform)  
7. **Power Dissipation:** High surge capability  
8. **Package:** SOD-323 (SC-76)  

### **Descriptions:**
- Designed for **ESD (Electrostatic Discharge) and surge protection** in low-voltage circuits.  
- Used in **high-speed data lines (USB, HDMI, Ethernet)** and **sensitive electronics** to suppress transient voltage spikes.  
- **Bidirectional** clamping ensures protection for both positive and negative voltage transients.  

### **Features:**
- **Low Clamping Voltage:** Provides effective protection for sensitive ICs.  
- **Fast Response Time:** Reacts quickly to transient events (nanosecond range).  
- **Compact Package:** SOD-323 footprint for space-constrained designs.  
- **RoHS Compliant:** Meets environmental standards.  

For exact parameters, refer to the **official datasheet** from the manufacturer.
