Description and Introduction

Optocoupler, Phototransistor Output The TCDT1100G is a reflective optical sensor manufactured by Vishay. Here are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Vishay  
- **Type:** Reflective Optical Sensor  
- **Package:** 4-Pin DIP  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Type:** Phototransistor  
- **Wavelength of Peak Sensitivity:** 950 nm (Infrared)  
- **Forward Current (IF):** 60 mA (Max)  
- **Reverse Voltage (VR):** 5 V (Max)  
- **Power Dissipation (PD):** 100 mW (Max)  
- **Collector-Emitter Voltage (VCEO):** 30 V (Max)  
- **Emitter-Collector Voltage (VECO):** 5 V (Max)  
- **Collector Current (IC):** 50 mA (Max)  

### **Descriptions:**  
- The TCDT1100G consists of an infrared emitting diode paired with a phototransistor in a reflective housing.  
- It detects objects by reflecting infrared light off a surface and measuring the intensity of the returned light.  
- Designed for applications requiring non-contact sensing, such as position detection, object counting, and encoder systems.  

### **Features:**  
- Compact 4-pin DIP package for easy integration.  
- High sensitivity to infrared light (950 nm peak).  
- Reliable performance across a wide temperature range (-40°C to +85°C).  
- Suitable for industrial and consumer electronics applications.  
- RoHS compliant.  

This information is strictly based on the manufacturer's datasheet. For detailed application notes or further technical support, refer to Vishay's official documentation.
