Procurement Notes

Verify the specific manufacturer part number 1F2 against official SMC Diode Solutions documentation to confirm active status and exact pinout compatibility. Ensure that the R-1 package dimensions match your PCB footprint requirements. Cross-reference datasheet parameters such as peak repetitive reverse voltage and forward current ratings with your circuit design constraints before finalizing procurement decisions.

Selection Notes

Select this component when a low-cost, through-hole standard diode is required for voltages up to 100 V. Consider thermal management capabilities if operating near the upper limit of the junction temperature range. Verify that the 1 A average current rating meets the continuous load requirements of the application without exceeding safe operating area limits defined in the official specifications.
