Single Diodes Procurement Notes

Verify the specific suffix (e.g., RHG) to confirm packaging details such as tape and reel configuration. Ensure the component meets RoHS compliance requirements if mandated by your design specifications. Cross-reference the datasheet version to confirm electrical characteristics match your system constraints before finalizing procurement.

Single Diodes Selection Notes

Select this component when a compact Schottky diode with low forward voltage is required for high-frequency switching or power efficiency. The SOD-123 package offers space savings compared to larger through-hole alternatives. Consider the 30V reverse voltage limit and 200mA current rating to ensure adequate headroom for the intended circuit operation.

Single Diodes Part Context

This part belongs to the BAT42W-BAT43W series of small signal Schottky diodes from Taiwan Semiconductor. These devices are engineered for general-purpose switching and rectification tasks where speed and low loss are critical. The series utilizes silicon technology optimized for surface-mount manufacturing processes.

Single Diodes Replacement Considerations

Check for direct pin-compatible substitutes within the same manufacturer's portfolio that share identical voltage and current ratings. Verify that any alternative component maintains the same SOD-123 footprint and thermal characteristics to ensure seamless integration without redesigning the PCB layout.
