Description and Introduction

TRANSIL The SMBJ12CA-TR is a surface-mount bidirectional TVS diode manufactured by STMicroelectronics (ST).  

### **Specifications:**  
- **Voltage - Reverse Standoff (Typ):** 12V  
- **Voltage - Breakdown (Min):** 13.3V  
- **Voltage - Clamping (Max) @ Ipp:** 19.9V (at 10A)  
- **Current - Peak Pulse (10/1000µs):** 10A  
- **Power - Peak Pulse:** 600W  
- **Operating Temperature:** -55°C to +150°C  
- **Package / Case:** DO-214AA (SMB)  
- **Mounting Type:** Surface Mount  
- **Polarity:** Bidirectional  

### **Descriptions:**  
The SMBJ12CA-TR is designed to protect sensitive electronics from voltage transients and surges. It offers bidirectional clamping, meaning it can suppress both positive and negative voltage spikes.  

### **Features:**  
- **High Surge Capability:** Handles high transient currents.  
- **Low Clamping Voltage:** Provides effective protection for sensitive circuits.  
- **Fast Response Time:** Reacts quickly to transient events.  
- **RoHS Compliant:** Meets environmental standards.  
- **Automotive Grade:** Suitable for automotive applications.  

This component is commonly used in power supplies, communication systems, and industrial electronics for ESD and surge protection.

Application Scenarios & Design Considerations

TRANSIL

Alternative Part Number

  • P6SMB12CA --: Same SMB (DO-214AA) package and 12V bidirectional TVS function with comparable 600W peak pulse power, widely available drop-in replacement.
  • 1SMB12CA --: Bidirectional 12V TVS diode in SMB package with similar clamping characteristics, suitable electrical alternative from a different series.
  • SMAJ12CA --: Bidirectional 12V TVS in SMA package; slightly lower 400W rating but usable in lower-surge applications and clearly different series naming.
  • 1SMB12CAT3G --: Bidirectional 12V SMB TVS diode with similar surge rating and clamping voltage, direct functional equivalent from a major supplier.
