Description and Introduction

Optocouplers The TCDT1102G is a phototransistor coupler manufactured by Toshiba. Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Type:** Phototransistor Output Optocoupler  
- **Isolation Voltage (Vrms):** 5000V  
- **Collector-Emitter Voltage (VCEO):** 80V  
- **Emitter-Collector Voltage (VECO):** 5V  
- **Collector Current (IC):** 50mA  
- **Power Dissipation (PC):** 100mW  
- **Current Transfer Ratio (CTR):** 50% (Min) at IF=5mA, VCE=5V  
- **Response Time (tPLH/tPHL):** 3µs (Typ)  
- **Operating Temperature Range:** -55°C to +110°C  

### **Description:**  
The TCDT1102G is a high-reliability optocoupler designed for signal isolation in electronic circuits. It consists of an infrared LED optically coupled to a phototransistor, providing electrical isolation between input and output.  

### **Features:**  
- High isolation voltage (5000Vrms)  
- Fast response time (3µs typical)  
- Compact 4-pin DIP package  
- Wide operating temperature range (-55°C to +110°C)  
- High current transfer ratio (CTR) for efficient signal transmission  

This optocoupler is commonly used in power supply feedback, industrial controls, and communication interfaces where electrical isolation is required.
