Product Description
Vishay SFH610A-1 DC Input Optocoupler is a reliable 4-Pin DIP device designed for signal transmission between electrically isolated circuits with a through-hole mounting format.
The device integrates a gallium arsenide (GaAs) infrared diode emitter, optically coupled to a silicon planar phototransistor detector, ensuring efficient and precise electrical isolation. It supports a maximum forward voltage of 1.65 V and can handle input currents up to 60 mA, suitable for various electronic and industrial applications.
The optocoupler exhibits a high isolation voltage rating of 5300 VRMS, providing robust protection in industrial, laboratory, and electronic power supply systems. It operates reliably in temperature ranges between -55°C and 100°C, catering to demanding environmental conditions.
With typical rise and fall times of 2 μs and 11 μs respectively, the SFH610A-1 ensures fast response times critical for digital signal transmission. The current transfer ratio (CTR) ranges from as low as 0.13% up to 80%, maintaining good linearity based on forward current, which contributes to stable performance.
This optocoupler complies with multiple international standards including DIN EN 60747-5-5 (VDE 0884), CSA 93751, UL1577, IEC 60065, and BSI IEC 60950, demonstrating its safety and quality certifications. It is ideal for use in industrial automation, control systems, electronic components for power and connectors, and signal isolation applications.
The coupler’s through-hole DIP package facilitates straightforward PCB assembly. It features end-stackable design with 2.54 mm pin spacing and ensures creepage and clearance distances above 8.0 mm in certain options. High collector-emitter voltage rating of 70 V supports a wide range of operating voltages.
Manufactured in Malaysia, the SFH610A-1 combines quality with durability. It is a versatile solution for electrical isolation needs in electronics and industrial sectors. Browse Vishay products and related Optocouplers at EnvMart for more options and technical support.
