Description and Introduction

Unidirectional TVS Array for Protection of Four Lines The SMDA12 is a transient voltage suppressor (TVS) diode manufactured by Microsemi. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Peak Pulse Power (PPP):** 1500W (10/1000μs waveform)  
- **Standoff Voltage (VWM):** 10.7V  
- **Breakdown Voltage (VBR):** 11.9V (min) to 13.2V (max) at IT  
- **Clamping Voltage (VC):** 19.9V at IPP  
- **Peak Pulse Current (IPP):** 75.8A  
- **Leakage Current (IR):** 1μA (max) at VWM  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AC (SMA)  

### **Descriptions:**  
- The SMDA12 is a unidirectional TVS diode designed to protect sensitive electronics from voltage transients and surges.  
- It is compliant with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge) standards.  
- Suitable for applications requiring high surge protection in a compact SMA package.  

### **Features:**  
- **Low Clamping Voltage:** Provides effective protection for sensitive components.  
- **Fast Response Time:** Responds quickly to transient events (sub-nanosecond).  
- **High Surge Capability:** Handles large transient currents.  
- **RoHS Compliant:** Meets environmental standards.  

This information is strictly based on the manufacturer's data for the SMDA12 TVS diode.
