Description and Introduction

LOW INPUT CURRENT PHOTOTRANSISTOR OPTICALLY COUPLED ISOLATORS The **SFH610-4** is an optocoupler manufactured by **SIEMENS** (now part of **Infineon Technologies**). Below are its specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Type:** Optocoupler (Phototransistor Output)  
- **Isolation Voltage:** 5300 Vrms (min)  
- **Collector-Emitter Voltage (VCEO):** 70 V  
- **Emitter-Collector Voltage (VECO):** 7 V  
- **Collector Current (IC):** 50 mA (max)  
- **Current Transfer Ratio (CTR):** 20% to 100% (at IF = 5 mA, VCE = 5 V)  
- **Response Time (tON / tOFF):** 3 µs / 4 µs (typical)  
- **Operating Temperature Range:** -55°C to +100°C  
- **Package:** DIP-6 (Dual In-line Package, 6-pin)  

### **Description:**  
The **SFH610-4** is a high-reliability optocoupler designed for signal isolation in industrial and consumer applications. It consists of an infrared LED optically coupled to a phototransistor, providing electrical isolation between input and output circuits.  

### **Features:**  
- **High Isolation Voltage:** Ensures safety in high-voltage applications.  
- **Wide CTR Range:** Provides flexibility in circuit design.  
- **Fast Switching Speed:** Suitable for digital signal transmission.  
- **Low Power Consumption:** Efficient for battery-operated devices.  
- **Reliable Performance:** Long-term stability in harsh environments.  

This optocoupler is commonly used in power supplies, industrial controls, and communication interfaces where electrical isolation is required.  

(Note: Since SIEMENS' semiconductor division was acquired by Infineon, some datasheets may reference Infineon as the current manufacturer.)
