Renesas Electronics DC Input Photocoupler Surface Mount 8-Pin SO Package PS9821-1-F3-AX

Renesas Electronics PS9821-1-F3-AX is a high-speed DC input photocoupler designed as an active-low type optocoupler integrating a GaAlAs light-emitting diode and a photodetector IC which combines a photodiode and signal processor on a single chip. This device is optimized for applications requiring high common mode transient immunity and minimal pulse width distortion, making it well-suited for dense electronic circuits.

The photocoupler’s surface mount 8-pin SO package facilitates compact PCB assembly with a 40% reduction in mounting area, aiding in space-constrained designs. It features a maximum forward voltage of 1.8 V and operates with an input current up to 12.5 mA. The device exhibits typical rise and fall times of 20 μs and 5 μs respectively, ensuring rapid signal transition and responsive operation.

With an isolation voltage rating of 566 V, the PS9821-1-F3-AX provides excellent electrical isolation between input and output, critical for protecting sensitive equipment and ensuring signal integrity in industrial and communication systems. The operating temperature range from -40°C to 85°C supports usage in harsh environments.

This device includes features such as low power consumption and an open collector output configuration, supporting flexible interfacing options. It is compliant with UL standards, assuring reliability and safety in a wide range of industrial applications. The component is supplied in tape and reel packaging suitable for automated pick-and-place assembly lines.

Typical applications include industrial automation controls, signal isolation in power supplies, telecommunications, and other high-density electronic systems that demand reliable and fast optoelectronic coupling.
