Product Description

Renesas Electronics PS9821-1-F3-AX is a high-speed DC input photocoupler designed for surface mounting in electronic assemblies. It features an active-low operation mode, combining a GaAlAs light-emitting diode on the input side and a photodetector IC with photodiode and signal processing circuitry on the output side within the same package.

This photocoupler is engineered for applications demanding high common mode transient immunity and low pulse width distortion, ideal for high density electronic circuits. The device offers an isolation voltage of 566V which enhances electrical separation between the input and output circuits, ensuring safety and reducing noise interference.

The PS9821-1-F3-AX comes in an 8-pin small-outline (SO) surface-mount package, with specifications supporting a maximum forward voltage of 1.8V and a maximum input current of 12.5mA. Typical switching speeds are 20 microseconds rise time and 5 microseconds fall time, enabling efficient signal transfer in various industrial and electronic control systems.

Operating temperature ranges from -40°C to 85°C making it suitable for industrial environments. The product is UL approved but is not rated for automotive standard compliance. Packaged in tape and reel format, it facilitates automated manufacturing processes.

High common mode transient immunity for noise-sensitive environments. Compact surface mount design reduces PCB space. Low power consumption supports efficient circuit design. Open collector output for flexible interfacing.

High isolation voltage ensures safety and noise reduction. Fast switching speeds support dynamic applications. Wide operating temperature range suits industrial use cases. UL approval certifies compliance with safety standards.

Packaged for automated assembly processes.
