Procurement Notes

Verify the specific manufacturer designation when sourcing, as multiple entities produce this part number. Confirm the package type matches the required PCB layout, typically DO-35 for this variant. Ensure the ordering suffix aligns with the desired packaging format. Cross-reference datasheets from authorized distributors to confirm electrical tolerances and thermal ratings before integration into final designs.

Selection Notes

Select this component for applications requiring rapid switching speeds and moderate current handling in a standard through-hole form factor. The 75 V reverse voltage rating suits low-voltage DC circuits. Consider thermal management requirements given the 500 mW power dissipation limit. Verify compatibility with operating temperature ranges specified in the official documentation.

Part Context

This component belongs to the standard 1N series of silicon rectifier diodes. It serves as a common replacement for legacy general-purpose diodes in consumer electronics and industrial control systems. The DO-35 package provides reliable axial lead mounting for automated or manual assembly processes.
