Description and Introduction

Photocoupler GaAs IRed & Photo -Transistor The TLP731 is an optocoupler (optical isolator) manufactured by Toshiba. Below are its key specifications, descriptions, and features:  

### **Manufacturer:** Toshiba  
### **Part Number:** TLP731  

### **Description:**  
The TLP731 is a high-speed photocoupler (optocoupler) that consists of a GaAlAs infrared LED optically coupled to a high-speed photodetector. It is designed for applications requiring electrical isolation and signal transmission.  

### **Key Features:**  
- **High-speed response:** Typical propagation delay time (tpHL) of 0.5 μs  
- **High isolation voltage:** 3750 Vrms (min)  
- **Low input current:** Forward current (IF) of 5 mA (typical)  
- **Compact package:** 4-pin DIP (Dual In-line Package)  
- **Wide operating temperature range:** -40°C to +85°C  
- **Open-collector output**  

### **Electrical Specifications:**  
- **Forward Current (IF):** 50 mA (max)  
- **Reverse Voltage (VR):** 5 V  
- **Output Collector-Emitter Voltage (VCEO):** 30 V  
- **Output Collector Current (IC):** 8 mA (max)  
- **Current Transfer Ratio (CTR):** 50% (min) at IF = 5 mA  

### **Applications:**  
- Digital signal isolation  
- Industrial control systems  
- Communication interfaces  
- Microprocessor system isolation  

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