The PS2801-1-F3 is a high-isolation photocoupler manufactured by Renesas Electronics. It integrates a gallium arsenide (GaAs) infrared light-emitting diode and an NPN silicon phototransistor in a compact 4-pin SSOP package, providing electrical isolation between input and output circuits.
With an isolation voltage rating of 2,500Vrms, the PS2801-1-F3 is designed for electronic systems that require signal isolation to help reduce the risk of electrical interference and protect low-voltage control circuitry from higher-voltage sections.
The output phototransistor features a maximum collector-emitter voltage of 80V and a maximum collector current rating of 50mA. Its current transfer ratio (CTR) ranges from 80% to 600% under specified test conditions, with the applicable CTR rank depending on the ordering specification.
The device offers typical rise and fall times of 3μs and 5μs, respectively, making it suitable for general-purpose signal transmission and switching applications where galvanic isolation is required.
The PS2801-1-F3 uses a compact 4-pin SSOP surface-mount package with a 1.27mm lead pitch. Its package structure incorporates shielding against ambient light, helping maintain stable optocoupler operation in high-density electronic assemblies.
With an operating ambient temperature range of -55°C to +100°C, this photocoupler is suitable for a variety of industrial control, instrumentation, and power supply applications. The F3 ordering suffix identifies the embossed tape-and-reel packaging option, with 3,500 pieces per reel.
