Description and Introduction

TRANSIL The SM4T18CA is a Transil™ diode manufactured by STMicroelectronics. Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Type:** Transient Voltage Suppressor (TVS) Diode  
- **Voltage - Reverse Standoff (V_RWM):** 18V  
- **Voltage - Breakdown (V_BR):** 20.1V (Min)  
- **Voltage - Clamping (V_CL):** 29.2V at 1A  
- **Peak Pulse Current (I_PP):** 1A (8/20µs)  
- **Power - Peak Pulse (P_PP):** 400W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AC (SMA)  

### **Descriptions:**  
- Designed for surge protection in electronic circuits.  
- Bidirectional TVS diode for ESD and transient overvoltage protection.  
- Low clamping voltage for effective circuit protection.  

### **Features:**  
- **High Surge Capability:** Handles transient events effectively.  
- **Fast Response Time:** Reacts quickly to overvoltage transients.  
- **Low Leakage Current:** Minimizes power loss in standby mode.  
- **Bidirectional Protection:** Guards against both positive and negative voltage spikes.  
- **RoHS Compliant:** Meets environmental standards.  

This diode is commonly used in automotive, industrial, and consumer electronics for protecting sensitive components from voltage surges.
