Description and Introduction

TVS Diode Array For ESD and Latch-Up Protection The SMS12.TCT is a transient voltage suppressor (TVS) diode manufactured by SEMTECH.  

### **Specifications:**  
- **Voltage - Reverse Standoff (VRWM):** 12V  
- **Voltage - Breakdown (VBR):** 13.3V (Min), 14.7V (Max)  
- **Voltage - Clamping (VC):** 19.9V at 1A  
- **Peak Pulse Current (IPP):** 1A  
- **Power - Peak Pulse (PPP):** 200W (8/20µs)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AC (SMA)  

### **Descriptions:**  
The SMS12.TCT is designed to protect sensitive electronics from voltage transients and electrostatic discharge (ESD). It provides fast response to transient overvoltage events, clamping excessive voltage to safe levels.  

### **Features:**  
- Low clamping voltage  
- Fast response time  
- High surge capability  
- RoHS compliant  
- Lead-free and halogen-free  

This diode is commonly used in applications such as power supplies, communication ports, and automotive systems for transient voltage protection.

Application Scenarios & Design Considerations

TVS Diode Array For ESD and Latch-Up Protection

Alternative Part Number

  • SP0503BAHT --: TVS diode array with similar clamping performance for ESD protection, widely available and pin-compatible in many designs.
  • PESD12VS1UB --: Single-line ESD protection diode with 12V standoff voltage, close electrical match to the SMS12 in a small SOD-523 package.
  • ESD9B12ST5G --: 12V ESD protection device with low capacitance and fast response, suitable drop-in replacement for transient suppression applications.
  • SM12.TCT --: Same 12V unidirectional TVS diode family from the original Semtech design source, with matching SOT-23 package and electrical characteristics.
  • SD12.TCT --: 12V TVS diode in SOT-23 with comparable peak pulse power and clamping performance, suitable as a drop-in functional replacement.
