Description and Introduction

LED DISPLAY The TLS346T is a photocoupler (optocoupler) manufactured by **TOSHIBA**. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Type**: Photocoupler with Phototransistor Output  
- **Isolation Voltage**: 5000Vrms (min)  
- **Collector-Emitter Voltage (VCEO)**: 80V (max)  
- **Emitter-Collector Voltage (VECO)**: 5V (max)  
- **Collector Current (IC)**: 50mA (max)  
- **Current Transfer Ratio (CTR)**: 50% (min) at IF = 5mA, VCE = 5V  
- **Input Forward Current (IF)**: 60mA (max)  
- **Reverse Input Voltage (VR)**: 5V (max)  
- **Operating Temperature Range**: -55°C to +110°C  
- **Package**: DIP4 (4-pin Dual In-line Package)  

### **Descriptions:**
- The **TLS346T** is a high-reliability photocoupler designed for signal isolation in electronic circuits.  
- It consists of a **GaAs infrared LED** optically coupled to a **silicon phototransistor**.  
- Suitable for applications requiring high-voltage isolation and noise immunity.  

### **Features:**
- **High Isolation Voltage**: 5000Vrms ensures reliable electrical isolation.  
- **Compact DIP4 Package**: Space-efficient and easy to mount on PCBs.  
- **Wide Operating Temperature Range**: Functions reliably in harsh environments.  
- **High CTR (Current Transfer Ratio)**: Ensures efficient signal transmission.  
- **Fast Response Time**: Suitable for high-speed switching applications.  

This information is based on TOSHIBA's official datasheet for the TLS346T photocoupler.
