Description and Introduction

Photocoupler (photo-IC output) The TLP351F is a photocoupler (or optocoupler) manufactured by **TOSHIBA**. Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Isolation Voltage:** 3750 Vrms (min)  
- **Collector-Emitter Voltage (VCEO):** 80 V (max)  
- **Collector Current (IC):** 50 mA (max)  
- **Current Transfer Ratio (CTR):** 100% (min) at IF = 5 mA  
- **Input Forward Current (IF):** 25 mA (max)  
- **Forward Voltage (VF):** 1.3 V (typ) at IF = 5 mA  
- **Turn-On Time (ton):** 0.5 μs (max)  
- **Turn-Off Time (toff):** 0.5 μs (max)  
- **Operating Temperature Range:** -40°C to +110°C  

### **Description:**  
The TLP351F is a high-speed **photocoupler** with a **GaAs infrared LED** optically coupled to a **phototransistor**. It is designed for **high-voltage isolation** and **fast switching** in applications such as **IGBT/MOSFET gate driving, industrial automation, and power supply control**.  

### **Features:**  
- **High-speed response** (0.5 μs max for both turn-on/off)  
- **High current transfer ratio (CTR ≥ 100%)**  
- **Wide operating temperature range** (-40°C to +110°C)  
- **Compact and surface-mount package (SO6L)**  
- **High isolation voltage (3750 Vrms)**  
- **Low input current requirement**  

The TLP351F is commonly used in **inverters, motor drives, and switching power supplies** due to its reliability and fast switching performance.
