It features inverse parallel LED configuration accepting both positive and negative input currents for AC signal detection. Provides 5000Vrms isolation voltage certified to UL1577 and high VCEO of 80V. The X1 suffix denotes A-grade current transfer ratio of 50-150% at IF=1mA, VCE=5V.","working_principle":"The PC814X1CSZ9F operates as an AC-input phototransistor coupler. (1) The input uses two inverse-parallel GaAs LEDs that emit infrared light when current flows in either direction, enabling AC signal detection. (2) The output silicon phototransistor is mounted opposite the LEDs with transparent insulation providing 5000Vrms isolation. The phototransistor generates collector current proportional to LED current with A-grade CTR of 50-150%. (3) The phototransistor operates in common-emitter with VCEO of 80V. The 18us rise\/fall time and 200mV VCE(sat) suit medium-speed signal isolation.","pin_description":"
