Single Diodes Procurement Notes

Verify the specific HE3 suffix indicates RoHS compliance and AEC-Q101 qualification status directly from the manufacturer datasheet. Confirm the SOD-123 package dimensions match your PCB footprint requirements. Ensure the operating temperature range aligns with your system's thermal environment. Check for any recent product change notices regarding material categorization or manufacturing location changes.

Single Diodes Selection Notes

Select this component when a small form factor Schottky diode with integrated ESD protection is required. The SOD-123 package offers space efficiency compared to larger through-hole options. Consider the 50 V reverse voltage limit and 200 mA current rating to ensure adequate headroom for your circuit design. Verify compatibility with automated assembly processes given the tape and reel packaging options available.

Single Diodes Part Context

This part belongs to Vishay's BAT43 series of small signal Schottky diodes designed for high-speed switching. The HE3 designation signifies lead-free construction with halogen-free molding compound. The WS suffix typically denotes the specific SOD-123 case style with enhanced mechanical stability. This series is widely used in consumer and automotive electronics where compact size and reliable performance are critical.

Single Diodes Replacement Considerations

BAT46W-HE3-08: Offers higher reverse voltage (100V) but lower forward current (150mA). BAT54W-HE3-08: Provides similar current handling (200mA) with 30V reverse voltage. Verify pinout compatibility and thermal characteristics before substitution.
