Description and Introduction

Silicon Avalanche Diodes - 600W Surface Mount Transient Voltage Supressors The SMBJ220A is a Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse. Here are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Voltage - Reverse Standoff (VRWM):** 220V  
- **Voltage - Breakdown (VBR):** 244V (min)  
- **Voltage - Clamping (VC):** 355V at 10A (IPP)  
- **Peak Pulse Current (IPP):** 10A (8/20µs waveform)  
- **Power - Peak Pulse (PPP):** 600W  
- **Operating Temperature:** -55°C to +150°C  
- **Package:** SMB (DO-214AA)  

### **Descriptions:**  
- Designed to protect sensitive electronics from voltage transients and surges.  
- Bi-directional (can suppress both positive and negative voltage spikes).  
- RoHS compliant.  

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

This information is based on Littelfuse's official datasheet for the SMBJ220A.

Application Scenarios & Design Considerations

Alternative Part Number

  • P6SMB220A --: Same 220V standoff unidirectional TVS in a similar SMB package with comparable clamping and power rating, from the same manufacturer.
  • 1SMB220AT3G --: Unidirectional 220V SMB TVS diode with matching standoff voltage and surge capability, widely available second source.
  • SMAJ220A --: 220V unidirectional TVS in SMA package; slightly lower power rating but electrically compatible for many clamping applications.
