H11AA1
by VISHAY(威世)
The H11AA1 from Vishay is an AC input optocoupler commonly used for isolated AC sensing and zero-crossing detection. Its opposing input LEDs allow optical coupling with either input polarity, while a phototransistor provides the output signal. This record represents the through-hole PDIP-6 version. A free download supplies the KiCad symbol with 6 pins, the PDIP-6_L8.5-W6.5-P2.54-LS7.6-BL footprint with 6 pads, and a 3D model to support board visualization. In support of conversion verification, 3 ProtoFlow engineers have used these assets in real designs. The optocoupler can be opened directly in ProtoFlow to incorporate it into a project.
