Product Description
Renesas Electronics PS9821-1-F3-AX is a high-speed DC input photocoupler designed as an active-low type with superior electrical characteristics. It incorporates a gallium aluminum arsenide (GaAlAs) light-emitting diode on the input side and a photodetector IC combining a photodiode and signal processor on the output side in a single 8-pin small outline (SO) surface mount package. This integration reduces mounting area by 40%, enabling compact high density circuit designs.
The device delivers high common mode transient immunity of up to 566V isolation voltage and low pulse width distortion, making it ideal for industrial, construction, laboratory, HVAC, manufacturing, and automation applications requiring robust electrical isolation and signal integrity. Its maximum forward voltage is 1.8V with a maximum DC input current of 12.5mA. The typical signal rise time is 20μs, and fall time is 5μs, ensuring high-speed operation.
The operational temperature range from -40°C to 85°C provides reliability in harsh environments. This photocoupler is UL approved, meets the PS series standards, and is not designed for automotive standard compliance. Packaged in tape and reel, it supports automated assembly and improved production throughput.
Key benefits include low power consumption and an open collector output, suitable for interfacing in a variety of electronic control systems. Its compact surface mount format optimizes board space and contributes to enhanced overall device performance.
