Description and Introduction

High Speed Optocoupler, 100 kBd, Low Input Current, High Gain The SFH6138 is an optocoupler manufactured by Vishay. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Isolation Voltage:** 5300 Vrms  
- **Current Transfer Ratio (CTR):** 50% to 600% (at IF = 5 mA, VCE = 5 V)  
- **Input Forward Current (IF):** 60 mA (maximum)  
- **Reverse Voltage (VR):** 6 V  
- **Collector-Emitter Voltage (VCEO):** 70 V  
- **Emitter-Collector Voltage (VECO):** 7 V  
- **Operating Temperature Range:** -55°C to +110°C  
- **Switching Time (Turn-on/turn-off):** 3 µs / 4 µs (typical)  
- **Package Type:** DIP-6  

### **Descriptions:**  
- The SFH6138 is a high-speed optocoupler with a GaAs infrared LED optically coupled to a phototransistor detector.  
- It provides electrical isolation between input and output circuits.  
- Suitable for applications requiring high-speed signal transmission and noise immunity.  

### **Features:**  
- High isolation voltage (5300 Vrms)  
- High current transfer ratio (CTR)  
- Fast switching speed  
- Wide operating temperature range  
- Compact DIP-6 package  

This information is based solely on the manufacturer's datasheet for the SFH6138 optocoupler.

Application Scenarios & Design Considerations

High Speed Optocoupler, 100 kBd, Low Input Current, High Gain

Alternative Part Number

  • HCPL-2631 --: Dual-channel high-speed optocoupler with similar logic output and speed, widely used as a drop-in functional replacement for the SFH6138.
  • 6N137 --: Single-channel high-speed 10 MBd optocoupler from the same manufacturer with comparable propagation delay and open-collector output.
  • TLP2361 --: High-speed logic-output optocoupler with similar CTR-independent operation and speed, suitable alternative when SFH6138 is unavailable.
