Description and Introduction

LOW CURRENT / HIGH GAIN OPTOCOUPLER The part **SFH6319T** is manufactured by **SIEMENS** (now under **OSRAM Opto Semiconductors**). Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Type:** Optocoupler / Phototransistor Output Optoisolator  
- **Input Type:** Infrared LED  
- **Output Type:** Phototransistor with Base Connection  
- **Isolation Voltage:** 5.3 kV (RMS)  
- **Current Transfer Ratio (CTR):** 50% (min) at 5mA input current  
- **Forward Current (IF):** 60 mA (max)  
- **Collector-Emitter Voltage (VCEO):** 70 V  
- **Operating Temperature Range:** -55°C to +100°C  
- **Package:** DIP-6 (Dual Inline Package)  

### **Descriptions:**  
- The SFH6319T is a high-reliability optocoupler designed for signal isolation in industrial and automotive applications.  
- It provides galvanic isolation between input and output circuits.  
- The phototransistor output includes a base pin for improved switching speed.  

### **Features:**  
- High isolation voltage (5.3 kV)  
- Fast switching response  
- Low CTR degradation over time  
- Wide operating temperature range  
- Compliant with industrial and automotive standards  

This part is commonly used in power supplies, motor controls, and communication interfaces requiring signal isolation.  

(Note: SIEMENS' optoelectronics division was acquired by OSRAM, so this part may now be listed under OSRAM.)
