Description and Introduction

BIDIRECTIONAL TRANSIL" ARRAY FOR DATALINE PROTECTION The **ITA18B3RL** is a **STMicroelectronics (STM)** component, specifically a **thyristor** (also known as a **SCR - Silicon Controlled Rectifier**). Below are its key specifications, descriptions, and features based on available data:

### **Specifications:**
- **Type:** Thyristor (SCR)  
- **Voltage Rating (VDRM/VRRM):** 800V (Peak Repetitive Off-State Voltage)  
- **Current Rating (IT(RMS)):** 18A (RMS On-State Current)  
- **Gate Trigger Current (IGT):** 5mA (Typical)  
- **Gate Trigger Voltage (VGT):** 1.5V (Typical)  
- **Holding Current (IH):** 5mA (Typical)  
- **Non-Repetitive Surge Current (ITSM):** 180A (Peak, 10ms)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-220AB (Through-Hole Mount)  

### **Descriptions:**
- Designed for **high-voltage switching applications** in AC power control.  
- Suitable for **motor control, lighting systems, and industrial automation**.  
- Features **high surge current capability** for robust performance.  

### **Features:**  
- **High voltage and current handling** (800V, 18A).  
- **Low gate trigger current** for easy control.  
- **Isolated tab** (TO-220AB insulated version available).  
- **Reliable switching performance** in harsh environments.
