Description and Introduction

TVS Diode Array For ESD and Latch-Up Protection The **SMS12C** is a **surge protection device (SPD)** manufactured by **PROTEK**. Below are the specifications, descriptions, and features based on available information:

### **Specifications:**
- **Type:** Secondary surge protector  
- **Voltage Rating:** 12V DC  
- **Max Continuous Operating Voltage (MCOV):** 15V DC  
- **Surge Current Rating:** 5kA (8/20µs waveform)  
- **Clamping Voltage:** <40V  
- **Response Time:** <1 nanosecond  
- **Connection Type:** Screw terminals  
- **Housing Material:** Flame-retardant thermoplastic  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- Designed to protect **low-voltage DC circuits** (such as **12V systems**) from transient voltage surges.  
- Suitable for **telecommunications, security systems, automotive electronics, and industrial control systems**.  
- Provides **fast-acting protection** against lightning-induced surges and switching transients.  

### **Features:**
- **Solid-state surge suppression technology** for reliable performance.  
- **Fail-safe design** – fails to a short circuit to protect downstream equipment.  
- **Compact and lightweight** for easy installation.  
- **UL 1449 Listed** (if applicable, verify with manufacturer).  
- **High surge current handling** for robust protection.  

For exact compliance and certifications, refer to the **official PROTEK datasheet**.

Application Scenarios & Design Considerations

TVS Diode Array For ESD and Latch-Up Protection

Alternative Part Number

  • SM12C --: Same 12V bidirectional TVS diode function in a similar SMB package, widely available and electrically compatible.
  • P6SMB12CA --: 600W bidirectional TVS with 12V standoff voltage, suitable drop-in protection replacement with higher surge rating.
  • SMBJ12CA --: Standard 600W bidirectional TVS in SMB package with 12V standoff, common cross-reference for SMS12C.
  • SM12.TCT --: Same manufacturer TVS diode in the SM series with similar 12V standoff and clamping performance, widely available and pin-compatible for ESD/transient protection.
  • PESD12VS1UB --: Single-line 12V ESD protection diode with comparable working voltage and low capacitance, suitable drop-in replacement for general transient suppression.
  • SD12C.TCT --: Semtech 12V TVS diode offering similar bidirectional clamping characteristics and package options, a practical alternate for circuit protection.
