Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Comchip Technology or authorized distributors before integration. Confirm that the SOT-23 package dimensions match your PCB footprint requirements. Ensure the automotive qualification meets your system's specific reliability standards. Check for any recent product change notices (PCNs) that might affect performance or packaging.

Selection Notes

Select this component when a common anode switching diode with high reverse voltage tolerance is required in a compact SOT-23 package. The low capacitance value makes it suitable for high-frequency switching tasks. Consider the 350 mW power dissipation limit for thermal management. Verify that the 225 mA current rating exceeds the maximum expected load current in your circuit design.

Part Context

This part belongs to Comchip Technology's automotive diode portfolio, designed for robust performance in vehicle electronics. It complements other general-purpose and power diodes offered by the manufacturer. The SOT-23 form factor allows for space-efficient board layouts compared to larger through-hole alternatives. It is distinct from their rectifier and TVS diode lines.
