Description and Introduction

Photocoupler Infrared LED + Photo IC The TLP550 is an optocoupler manufactured by Toshiba. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Manufacturer:**  
- **Toshiba**  

### **Description:**  
- The TLP550 is a photocoupler (optocoupler) that consists of a GaAlAs infrared LED optically coupled to a high-speed phototransistor.  
- It is designed for high-speed signal transmission in digital and analog circuits while providing electrical isolation.  

### **Key Features:**  
- **High-speed response:**  
  - Propagation delay time (tPLH): 3 µs (max)  
  - Propagation delay time (tPHL): 3 µs (max)  
- **High isolation voltage:**  
  - 3750 Vrms (min) between input and output  
- **Operating temperature range:**  
  - -55°C to +110°C  
- **Current Transfer Ratio (CTR):**  
  - 50% (min) at IF = 5 mA, VCE = 5 V  
- **Low input current requirement:**  
  - Forward current (IF): 20 mA (max)  
- **Output transistor collector-emitter voltage (VCEO):**  
  - 30 V (min)  

### **Applications:**  
- High-speed digital signal isolation  
- Industrial control systems  
- Communication interfaces  
- Power supply feedback circuits  

### **Package Type:**  
- **DIP (Dual In-line Package), 6-pin**  

This information is based on Toshiba's official datasheet for the TLP550. For detailed electrical characteristics and performance graphs, refer to the manufacturer's documentation.
