onsemi Optocoupler Surface Mount, 6-Pin SOP Package, CMOS Output, Max Forward Voltage 1.8V, 20mA Input Current, FOD8173T

onsemi FOD8173T is a high-performance optocoupler featuring a surface mount 6-pin small outline plastic package (SOP) designed for electrical isolation in complex systems. The device combines an aluminium gallium arsenide (AlGaAs) LED and CMOS detector IC integrating a photodiode, a high-speed transimpedance amplifier, and a voltage comparator with a totem-pole output driver enabling CMOS output.

This optocoupler guarantees operational stability across an industrial temperature range of -40°C to 100°C and supports supply voltages between 3 V and 5.5 V. The FOD8173T offers a maximum forward voltage of 1.8 V on the input LED and a maximum input current of 20 mA. It features fast switching with a typical rise time and fall time of 7 ns, and a maximum pulse width distortion of 20 ns, making it ideal for high-speed digital isolation tasks.

Its insulation characteristics include an 8 mm creepage and clearance distance and 0.4 mm insulation distance, which provide robust protection against electrical hazards. The device is rated for a minimum common mode transient immunity (CMTI) of 20 kV/μs and supports data rates up to 20 Mbit/sec (non-return-to-zero format).

Typical applications of the FOD8173T include microprocessor system interfaces, industrial communication protocols such as fieldbus systems, programmable logic controller interfaces, isolated data acquisition systems, and voltage level translators. The device’s compliance to DIN-EN/IEC60747-5-5 and UL1577 standards underscores its reliability and safety in industrial and commercial use cases.

Surface mount 6-pin SOP construction ensures compact size and ease of assembly. AlGaAs LED and CMOS detector with integrated photodiode enhances signal integrity. Guaranteed operation from -40°C to 100°C suits demanding industrial environments.

Creepage and clearance distances meet industrial isolation requirements. High-speed output compatible with 3.3 V and 5 V CMOS logic. Data rate support of 20 Mbit/sec enables modern digital communication standards. Applications cover microprocessor interfaces, industrial control, and data acquisition.
