Description and Introduction

Surface mount transient voltage suppressor. 600 watts peak power. Reverse stand-off voltage VRWM = 120 V. Test current IT = 1 mA. The SMBJ120CA is a bidirectional TVS (Transient Voltage Suppressor) diode manufactured by CONCORD.  

### **Specifications:**  
- **Voltage - Reverse Standoff (VRWM):** 120V  
- **Voltage - Breakdown (VBR):** 133V (Min)  
- **Voltage - Clamping (VC):** 193V (Max) at 10A  
- **Peak Pulse Current (IPP):** 10A (8/20µs)  
- **Power - Peak Pulse (PPP):** 600W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** SMB (DO-214AA)  

### **Descriptions and Features:**  
- Designed for transient voltage suppression in electronic circuits.  
- Bidirectional polarity for protection against both positive and negative voltage transients.  
- Low clamping voltage for effective surge protection.  
- Fast response time to transient events.  
- RoHS compliant and lead-free.  
- Suitable for applications in telecommunications, automotive, and industrial systems.

Application Scenarios & Design Considerations

Surface mount transient voltage suppressor. 600 watts peak power. Reverse stand-off voltage VRWM = 120 V. Test current IT = 1 mA.

Alternative Part Number

  • P6SMB120CA --: Same SMB (DO-214AA) package, 600W bidirectional TVS with 120V standoff, widely available and pin-compatible drop-in replacement.
  • 1SMB120CA --: SMB-packaged 600W bidirectional transient voltage suppressor with matching 120V working voltage, suitable direct substitute.
  • SMAJ120CA --: Bidirectional 400W TVS in SMA package with 120V standoff; lower power rating but usable in less demanding clamping applications and from a different series.
  • 1SMB120CAT3G --: 600W bidirectional transient voltage suppressor with matching 120V standoff and SMB footprint, widely available.
