Description and Introduction

Programmable Controllers AC / DC?Input Module Telecommunication The TLP620-4GB is a photocoupler (optoisolator) manufactured by Toshiba. Below are its specifications, descriptions, and features based on available factual information:  

### **Specifications:**  
- **Type:** Photocoupler (Optocoupler)  
- **Package:** DIP4 (Dual In-line Package, 4-pin)  
- **Isolation Voltage:** 5,000Vrms (min)  
- **Input Current (IF):** 50mA (max)  
- **Output Type:** Phototransistor  
- **Collector-Emitter Voltage (VCEO):** 55V (min)  
- **Current Transfer Ratio (CTR):** 50% (min at IF = 10mA, VCE = 5V)  
- **Switching Speed:**  
  - Turn-on time (ton): 3μs (max)  
  - Turn-off time (toff): 4μs (max)  
- **Operating Temperature Range:** -55°C to +110°C  

### **Descriptions:**  
- The TLP620-4GB is a high-speed photocoupler with a GaAs infrared LED and a phototransistor detector.  
- It provides electrical isolation between input and output circuits, making it suitable for noise suppression and signal transmission in industrial and consumer electronics.  

### **Features:**  
- **High Isolation Voltage:** 5,000Vrms ensures reliable insulation.  
- **High-Speed Switching:** Fast response time for digital signal transmission.  
- **Compact DIP4 Package:** Space-efficient design.  
- **Wide Operating Temperature Range:** Suitable for harsh environments.  
- **Compliant with Safety Standards:** Meets international safety and reliability requirements.

Application Scenarios & Design Considerations

Programmable Controllers AC / DC?Input Module Telecommunication

Alternative Part Number

  • PC817C --: Widely available single-channel phototransistor optocoupler with similar CTR and isolation ratings; use four devices to replace the quad-channel part.
  • LTV-847 --: Quad-channel phototransistor optocoupler in DIP-16, a common drop-in style replacement for TLP620-4 series.
  • PC847 --: Quad-channel phototransistor optocoupler with comparable CTR and isolation, suitable as a functional substitute.
  • PC817 --: Widely available general-purpose optocoupler with similar CTR and isolation ratings; single-channel so four units needed for quad applications, but a proven, low-cost substitute.
