Data rate of 15 Mbps supports Profibus, DeviceNet, and other industrial fieldbuses running at 12 Mbps or lower. Isolation rating of 2500 Vrms covers basic insulation for 240 VAC mains-powered equipment. The 15 kV/µs CMTI ensures the output stays clean when the input side experiences fast voltage transients from IGBT switching or relay coil kickback — a common failure point in motor drives and inverters. Forward voltage (Vf) typical 1.65 V with a 20 mA max forward current means the LED side can be driven directly from a 3.3 V logic output through a current-limiting resistor. Rise/fall times of 20 ns and 5 ns respectively, combined with the 75 ns propagation delay, give enough timing margin for most 15 Mbps NRZ serial links. ## Active lifecycle — no EOL risk for new designs","metaTitle":"PS9821-1-F3-AX Optoisolator, 15Mbps, Open Collector, 8-SSOP","metaDescription":"PS9821-1-F3-AX NEPOC series 1-channel optocoupler: 15Mbps data rate, 2500Vrms isolation, 15kV/µs CMTI, open-collector output.
