• Forward Voltage (VF): 1.65 V (typical at IF = 10 mA)
• Reverse Voltage (VR): 6 V
• Switching Time (Turn-on/turn-off): 3 µs / 4 µs (typical)
• Operating Temperature Range: -55°C to +100°C

Description:

The SFH600-1 is a high-reliability optocoupler designed for signal isolation in industrial and automotive applications. It consists of an infrared LED optically coupled to a silicon phototransistor, providing electrical isolation between input and output circuits.

Features:

• High isolation voltage (5300 Vrms)
• Fast switching response
• Wide operating temperature range
• High current transfer ratio (CTR)
• Compact DIP-6 package
• Suitable for harsh environments

This optocoupler is commonly used in power supplies, motor control, and digital logic isolation applications.

(Note: Since SIEMENS' optoelectronics division was acquired by Infineon, newer versions or replacements may exist under Infineon branding.)
