Description and Introduction

Optocouplers The SFH6156-2 is an optocoupler manufactured by Vishay Semiconductors. Below are its key specifications, descriptions, and features:

### **Manufacturer:**  
Vishay Semiconductors  

### **Description:**  
The SFH6156-2 is a high-reliability optocoupler with a GaAs infrared LED optically coupled to a phototransistor detector. It is designed for signal isolation in electronic circuits, providing electrical isolation between input and output.  

### **Features:**  
- **Isolation Voltage:** 5300 Vrms (min)  
- **Current Transfer Ratio (CTR):** 50% (min) at IF = 5 mA, VCE = 5 V  
- **High-Speed Switching:** Rise time (tr) = 4 μs (max), Fall time (tf) = 3 μs (max)  
- **Low Input Current Requirement:** Forward current (IF) = 1.6 mA (max) for logic-level compatibility  
- **Operating Temperature Range:** -55°C to +100°C  
- **Package Type:** DIP-6 (Dual Inline Package, 6-pin)  
- **Compliance:** UL, CSA, and VDE safety approvals  

### **Applications:**  
- Signal isolation in industrial controls  
- Microprocessor system interfaces  
- Power supply feedback circuits  
- Digital logic isolation  

This optocoupler is widely used in applications requiring high-voltage isolation and reliable signal transmission.

Application Scenarios & Design Considerations

Optocouplers

Alternative Part Number

  • PC817X2NSZ0F --: Standard through-hole optocoupler with CTR rank comparable to the SFH6156-2; widely available and pin-compatible in most circuits.
  • LTV-817S --: SMD optocoupler with similar CTR and isolation ratings, suitable drop-in replacement for many SFH6156-2 applications.
  • EL817S1 --: Low-cost SMD optocoupler with comparable current transfer ratio and 5 kV isolation, good second-source option.
