Description and Introduction

TVS Diode Array The part **SM15.TCT** is manufactured by **SEMTECH**. Below are the specifications, descriptions, and features based on the available knowledge:  

### **Specifications:**  
- **Type:** TVS Diode (Transient Voltage Suppressor)  
- **Configuration:** Unidirectional  
- **Peak Pulse Power:** 1500W (8/20µs)  
- **Breakdown Voltage (VBR):** Typically 18.7V (min 17.4V, max 20.0V)  
- **Clamping Voltage (VC):** 29.2V at 1A  
- **Standoff Voltage (VRWM):** 15V  
- **Reverse Leakage Current (IR):** 1µA (max at VRWM)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AA (SMB)  

### **Descriptions:**  
- Designed for **ESD (Electrostatic Discharge) protection** and **surge suppression** in electronic circuits.  
- Protects sensitive components from **transient voltage spikes** in applications like power lines, data lines, and communication interfaces.  
- **Unidirectional** operation means it clamps voltage spikes in one polarity while acting as a regular diode in the reverse direction.  

### **Features:**  
- **Low clamping voltage** for effective protection.  
- **Fast response time** (sub-nanosecond) to suppress transients.  
- **High surge capability** (1500W peak pulse power).  
- **RoHS compliant** and halogen-free.  
- Suitable for **automotive, industrial, and consumer electronics** applications.  

For exact values and application-specific details, always refer to the **official SEMTECH datasheet**.

Application Scenarios & Design Considerations

TVS Diode Array

Alternative Part Number

  • SMAJ15A --: Unidirectional TVS diode in SMA package with 15V standoff voltage, matching the SM15.TCT's clamping role and drop-in compatible footprint.
  • P4SMA15A --: SMA-packaged 400W unidirectional TVS with 15V working voltage, offering similar surge protection and pin-compatible layout.
  • SMBJ15A --: SMB-packaged 600W TVS diode with 15V standoff, providing higher surge capability as a robust alternative if board space allows.
