Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMAJ17A is a transient voltage suppressor (TVS) diode manufactured by FAIRCHILD. Below are its specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Peak Pulse Power (PPP):** 400W (8/20μs waveform)  
- **Breakdown Voltage (VBR):** 19V (min) – 21.1V (max)  
- **Standoff Voltage (VRWM):** 17V  
- **Clamping Voltage (VC):** 27.6V (at IPP = 1A)  
- **Maximum Reverse Leakage Current (IR):** 1μA (at VRWM)  
- **Junction Capacitance (CJ):** 500pF (typical)  
- **Operating Temperature Range:** -55°C to +150°C  

### **Descriptions:**  
- The SMAJ17A is a unidirectional TVS diode designed to protect sensitive electronics from voltage transients and electrostatic discharge (ESD).  
- It is compliant with **IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge)** standards.  
- The device is housed in a **DO-214AC (SMA) package**, making it suitable for surface-mount applications.  

### **Features:**  
- **Low Clamping Voltage** for effective transient suppression.  
- **Fast Response Time** (typically <1ps) to quickly divert transient surges.  
- **High Surge Capability** for robust protection.  
- **Unidirectional Polarity** for protection against positive transients.  
- **RoHS Compliant** for environmental safety.  

This information is strictly based on manufacturer datasheets and technical documentation.

Application Scenarios & Design Considerations
