Description and Introduction

IRed & photo−transistor, for programmable controllers, AC / DC−input module and solid state relay The TLP531GB is an optocoupler manufactured by **TOSHIBA**. Below are its specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Type**: Photocoupler (Optocoupler) with a **GaAs infrared LED** and a **phototransistor**.  
- **Isolation Voltage**: **5000 Vrms** (min).  
- **Collector-Emitter Voltage (VCEO)**: **80 V** (max).  
- **Collector Current (IC)**: **50 mA** (max).  
- **Current Transfer Ratio (CTR)**: **50% min** (at IF = 5 mA, VCE = 5 V).  
- **Response Time**: **Turn-on time (ton) = 3 μs max**, **Turn-off time (toff) = 4 μs max**.  
- **Operating Temperature Range**: **-55°C to +110°C**.  
- **Package**: **DIP6 (6-pin Dual In-line Package)**.  

### **Descriptions:**  
- The **TLP531GB** is designed for **high-speed signal transmission** while maintaining **electrical isolation** between circuits.  
- It is commonly used in **industrial control systems, communication interfaces, and power supply feedback circuits**.  
- The device ensures **high reliability** and **long-term stability** due to TOSHIBA’s optoelectronic technology.  

### **Features:**  
- **High isolation voltage (5000 Vrms)** for safe signal transfer.  
- **Fast switching speed** (microsecond response time).  
- **High current transfer ratio (CTR ≥ 50%)** for efficient signal transmission.  
- **Wide operating temperature range** (-55°C to +110°C).  
- **Compact DIP6 package** for easy PCB mounting.  

For exact datasheet details, refer to **TOSHIBA’s official documentation** for the TLP531GB.

Application Scenarios & Design Considerations

IRed & photo−transistor, for programmable controllers, AC / DC−input module and solid state relay

Alternative Part Number

  • PC817X2NSZ0F --: Standard 4-pin DIP photocoupler with CTR rank comparable to the GB grade, widely available and pin-compatible replacement.
  • EL817(C) --: Popular 4-pin DIP optocoupler with similar CTR binning and isolation ratings, good second-source option.
  • LTV-817S-TA1 --: Equivalent 4-pin DIP phototransistor optocoupler with matching CTR range, suitable drop-in alternative.
  • LTV-817S --: DIP-4 phototransistor optocoupler with equivalent CTR range and 5 kV isolation, a cost-effective drop-in alternative for TLP531GB.
