Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm package type and tape/reel specifications. Ensure the ordering part number matches the required insulation voltage and data rate for your circuit design. Cross-reference the manufacturer number with authorized distributors to confirm availability and authenticity before placing orders.

Selection Notes

Select this component when a single-channel high-speed isolator with 1 Mb/s data rate is required. Consider the 5000 Vrms insulation rating for safety-critical applications. Verify that the 16 mA forward current and 8 mA output current meet the drive requirements of the connected logic or power stages within the specified temperature range.

Part Context

This part belongs to the PS8502L series of high-speed optocouplers from Renesas Electronics. The series is designed for applications demanding fast signal transmission and strong isolation. The L2 variant typically denotes specific pinout or packaging configurations within the family, distinct from other variants like PS8502L1.

Replacement Considerations

Check for direct substitutes such as PS8502L1-AX if package or minor parameter differences are acceptable. Verify compatibility with existing PCB footprints and electrical characteristics before substituting.
