Description and Introduction

TRANSIL The SM4T12A is a Transil™ diode manufactured by STMicroelectronics, designed for surge protection applications. Below are the factual details from Ic-phoenix technical data files:

### **Manufacturer:**  
STMicroelectronics  

### **Specifications:**  
- **Type:** Transil™ diode (TVS - Transient Voltage Suppressor)  
- **Peak Pulse Power (PPP):** 400W (8/20μs)  
- **Breakdown Voltage (VBR):** 13.3V (min) to 14.7V (max)  
- **Clamping Voltage (VC):** 19.9V (at IPP = 1A)  
- **Standoff Voltage (VRWM):** 12V  
- **Reverse Leakage Current (IR):** 1μA (max at VRWM)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AC (SMA)  

### **Descriptions:**  
- Designed for **transient overvoltage protection** in electronic circuits.  
- Suitable for **ESD (Electrostatic Discharge) and surge protection** in low-voltage applications.  
- **Bidirectional** configuration, protecting against both positive and negative transients.  
- Compliant with **IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge)** standards.  

### **Features:**  
- **Low clamping voltage** for effective protection.  
- **Fast response time** (typically <1ns).  
- **High surge capability** (400W peak pulse power).  
- **RoHS compliant** and halogen-free.  
- **Automotive-grade** options available (AEC-Q101 qualified).  

This information is strictly based on the manufacturer's datasheet and technical documentation.
