Description and Introduction

Photocoupler GaAlAs Ired & Photo IC The TLP251 is an optocoupler manufactured by Toshiba. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Manufacturer:** Toshiba  

### **Description:**  
The TLP251 is a photocoupler (optocoupler) that consists of a GaAlAs light-emitting diode (LED) optically coupled to a high-speed integrated photodetector. It is designed for high-speed signal transmission while providing electrical isolation between input and output circuits.  

### **Key Features:**  
- **High-speed response:** Typical propagation delay time (tpHL/tpLH) of 0.5 µs.  
- **High isolation voltage:** 5,000 Vrms (min) between input and output.  
- **Low input current:** Forward current (IF) of 5 mA (max) for reliable operation.  
- **Wide operating temperature range:** -40°C to +100°C.  
- **Compact package:** Available in a 6-pin DIP (Dual In-line Package).  
- **Output type:** Open-collector output with a built-in pull-up resistor.  
- **Supply voltage (VCC):** 10 V to 30 V for the output side.  

### **Applications:**  
- Isolated signal transmission in industrial controls.  
- Switching power supplies.  
- Inverter circuits.  
- Microprocessor system interfaces.  

This information is strictly based on the manufacturer's datasheet and technical documentation. No additional recommendations or interpretations are included.
