Description and Introduction

SMD Transient Voltage Suppressor The SMAJ190A is a transient voltage suppressor (TVS) diode manufactured by Microsemi. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Peak Pulse Power (10/1000μs):** 400W  
- **Standoff Voltage (VWM):** 171V  
- **Breakdown Voltage (VBR):** 190V (min)  
- **Clamping Voltage (VC):** 308V (max) at 10A  
- **Maximum Reverse Leakage Current (IR):** 1μA at VWM  
- **Operating Temperature Range:** -55°C to +150°C  
- **Junction Capacitance (CJ):** 50pF (typical)  
- **Package:** DO-214AC (SMA)  

### **Descriptions:**  
- The SMAJ190A is a unidirectional TVS diode designed to protect sensitive electronics from high-voltage transients.  
- It is compliant with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge) standards.  
- The device offers fast response time (typically <1ps) for overvoltage protection.  

### **Features:**  
- **High Surge Capability:** Handles transient surges up to 400W.  
- **Low Clamping Voltage:** Provides effective protection by limiting voltage spikes.  
- **RoHS Compliant:** Meets environmental standards.  
- **Unidirectional Operation:** Protects against positive voltage transients.  
- **SMA Package:** Compact surface-mount design for PCB applications.
