PC814X is listed in the Transistor, Photovoltaic Output Optoisolators range at ChipApex. The manufacturer field lists Sharp Microelectronics. Its product description is OPTOISOLATOR 5KV 1CH TRANS 4-DIP. Review the specifications below when checking this part for your BOM.
The PC814X is a single-channel optocoupler featuring an infrared LED coupled to a phototransistor. It utilizes a 4-pin DIP package, with surface-mount鸥翼 variants available. The device provides high isolation voltage of 5.0kVrms between input and output. Key electrical parameters include a collector-emitter voltage of 80V and a current transfer ratio (CTR) ranging from 20% to 300%. It operates within a temperature range of -30°C to 100°C.
Verify the specific suffix code (e.g., X1, XPJ000F) to confirm package type and CTR rank. Ensure compliance with UL1577 or VDE certification requirements if applicable to the target market. Confirm that the selected variant matches the required isolation voltage and operating temperature range for the specific application environment.
Select based on the required current transfer ratio range and package style. The standard DIP version suits through-hole assembly, while SMD versions are for surface mount. Verify that the 80V collector-emitter voltage meets the load requirements. Check for specific certification needs such as UL or VDE before finalizing the part number.
The PC814X belongs to Sharp's PC814 series of optocouplers. It is designed for general-purpose isolation applications where reliable signal transmission across potential barriers is required. The series includes various package options and CTR grades to accommodate different design constraints.
