Single Diodes Procurement Notes

Verify the specific ordering suffix '-7' corresponds to the 3000-unit tape and reel packaging configuration. Confirm that the component meets RoHS compliance requirements and holds Halogen-free status as defined by the manufacturer's green product definitions. Ensure the procurement channel is authorized to guarantee valid PPAP capability documentation for automotive integration.

Single Diodes Selection Notes

Select this component when a low-profile surface mount Schottky rectifier is required for automotive circuits. The 40 V reverse voltage rating suits low-voltage DC systems. Consider the thermal resistance values relative to the PCB material, such as FR-4 or polyimide, to ensure adequate heat dissipation under continuous load conditions without exceeding junction temperature limits.

Single Diodes Part Context

This part belongs to the PD3S series of Schottky barrier rectifiers manufactured by Diodes Incorporated. The series is characterized by its use in demanding automotive environments where space constraints and reliability are critical. The POWERDI323 package offers a balance between current handling capacity and minimal footprint compared to larger through-hole alternatives.

Single Diodes Replacement Considerations

Direct substitutes must match the 40 V reverse voltage, 1.0 A forward current, and POWERDI323 package dimensions. Verify that any replacement also holds AEC-Q101 qualification if used in automotive contexts. Check forward voltage and leakage current specifications to ensure compatibility with existing circuit performance requirements.
