Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Sharp Microelectronics or authorized distributors before procurement. Confirm that the SMD-4 package dimensions match your PCB footprint requirements. Ensure that the operating temperature range meets your application's environmental conditions. Check for any recent product change notifications regarding manufacturing location or material composition updates.

Selection Notes

Select this component when high isolation voltage and moderate speed are required in a small form factor. The 70V output voltage rating suits low-to-medium voltage logic interfaces. Compare against similar Sharp models like PC123X1YIP1B if higher collector current or different packaging is needed. Ensure the 20 mA forward current capability aligns with your driving circuit design constraints.

Part Context

This part belongs to Sharp's PC123 series of transistor output optocouplers. The series offers various configurations including Darlington and standard transistor outputs with different isolation voltages and packages. The PC123P2J000F specifically targets applications requiring 5kV isolation in a surface-mount format, distinguishing it from through-hole variants in the same family.

Replacement Considerations
