Description and Introduction

Silicon Avalanche Diodes - 400W Surface Mount Transient Voltage Supressors The SMAJ220A is a Transient Voltage Suppressor (TVS) diode manufactured by LITTELFUSE. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Peak Pulse Power (10/1000μs):** 400W  
- **Standoff Voltage (VWM):** 220V  
- **Breakdown Voltage (VBR):** 244V (min)  
- **Clamping Voltage (VC):** 357V at 1A  
- **Maximum Reverse Leakage Current (IRM):** 1μA at VWM  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AC (SMA)  

### **Descriptions:**
- Designed to protect sensitive electronics from high-voltage transients.  
- Bi-directional TVS diode for AC or DC circuits.  
- RoHS compliant and halogen-free.  

### **Features:**
- Fast response time (typically <1ps).  
- Low incremental surge resistance.  
- High reliability and surge capability.  
- Meets IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge) standards.
