Description and Introduction

PHOTO-INTERRUPTER INFRARED LED + PHOTOTRANSISTOR The TLP814 is an optocoupler manufactured by Toshiba. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
Toshiba  

### **Part Number:**  
TLP814  

### **Description:**  
The TLP814 is a photocoupler (optocoupler) that consists of a GaAlAs infrared LED optically coupled to a phototransistor. It is designed for signal transmission between circuits with different voltage levels while maintaining electrical isolation.  

### **Key Features:**  
- **Isolation Voltage:** 5000 Vrms (min)  
- **Current Transfer Ratio (CTR):** 50% (min) at IF = 5 mA, VCE = 5 V  
- **High-Speed Response:**  
  - Turn-on time (ton): 4 μs (max)  
  - Turn-off time (toff): 3 μs (max)  
- **Operating Temperature Range:** -55°C to +110°C  
- **Package Type:** DIP4 (4-pin Dual In-line Package)  
- **Input-Output Isolation:** AC and DC isolation  

### **Electrical Specifications:**  
- **Forward Current (IF):** 50 mA (max)  
- **Reverse Voltage (VR):** 5 V (max)  
- **Collector-Emitter Voltage (VCEO):** 80 V (min)  
- **Emitter-Collector Voltage (VECO):** 7 V (max)  

### **Applications:**  
- Signal isolation in industrial controls  
- Digital logic interfacing  
- Power supply feedback circuits  
- Microprocessor system interfaces  

This information is based on Toshiba's official datasheet for the TLP814 optocoupler.
