Description and Introduction

Optocouplers Here is the factual information about the part TCET1108G from the manufacturer SI:  

### **Manufacturer:** SI (Siliconix or Vishay Siliconix)  

### **Specifications:**  
- **Type:** Optocoupler / Optoisolator  
- **Input Type:** LED (Infrared)  
- **Output Type:** Phototransistor  
- **Isolation Voltage:** Typically 5000Vrms  
- **Current Transfer Ratio (CTR):** Minimum 20% (varies by batch)  
- **Forward Current (IF):** 60mA (max)  
- **Reverse Voltage (VR):** 5V (max)  
- **Collector-Emitter Voltage (VCEO):** 30V (max)  
- **Operating Temperature Range:** -55°C to +100°C  
- **Package Type:** DIP-4 (Dual In-line Package, 4-pin)  

### **Descriptions:**  
The TCET1108G is an optocoupler that provides electrical isolation between input and output circuits using an infrared LED and a phototransistor. It is commonly used for signal isolation, noise suppression, and interfacing in digital and analog circuits.  

### **Features:**  
- High isolation voltage (5000Vrms)  
- Compact DIP-4 package  
- Fast switching response  
- Reliable performance in harsh environments  
- Compatible with standard PCB assembly processes  

This information is based on available datasheets and manufacturer specifications. For precise details, always refer to the official datasheet.
