Description and Introduction

Optocoupler, Phototriac Output, High dV/dt, Very Low Input Current The IL4218 is a phototriac driver optocoupler designed for interfacing between low-voltage control circuits and high-voltage AC loads.  

### **Manufacturer Specifications:**  
- **Isolation Voltage:** 5300 Vrms  
- **Peak Off-State Voltage (VDRM):** 600 V  
- **Peak Repetitive Surge Current (ITSM):** 1 A (for 10 ms)  
- **Trigger Current (IFT):** 5 mA (max)  
- **Output Current (IT(RMS)):** 300 mA  
- **Operating Temperature Range:** -40°C to +100°C  
- **Package Type:** DIP-6 (Dual In-Line Package)  

### **Descriptions:**  
- The IL4218 is a zero-crossing optocoupler, meaning it triggers the triac near the zero-crossing point of the AC waveform, reducing EMI and inrush current.  
- It consists of an infrared LED optically coupled to a phototriac, providing electrical isolation between input and output.  
- Suitable for driving resistive, inductive, or capacitive loads in AC mains applications.  

### **Features:**  
- **Zero-Crossing Detection:** Reduces switching noise and stress on the load.  
- **High Isolation Voltage:** Ensures safety in high-voltage applications.  
- **Low Trigger Current:** Compatible with low-power control circuits.  
- **Compact DIP-6 Package:** Easy to integrate into PCB designs.  
- **High Noise Immunity:** Suitable for industrial environments.
