Single Diodes Procurement Notes

Verify the exact part number suffix, as 'BAS70B5003' may refer to the BAS70-05 variant or similar family members. Confirm availability status, as some BAS70 series variants are marked obsolete. Ensure the supplier provides official Infineon documentation to validate the specific electrical characteristics and package type before procurement.

Single Diodes Selection Notes

Select this component when a small-signal Schottky diode array is required for high-speed applications. The 70V rating suits low-voltage DC circuits. Consider the SOT-23-3 footprint for space-constrained designs. Verify thermal management requirements, as the junction temperature limit is 150°C. Ensure the application does not exceed the 70mA average forward current per diode.

Single Diodes Part Context

This component belongs to the BAS70 series of silicon Schottky diodes designed for high-speed switching. The series offers various voltage ratings and configurations. The BAS70B5003 specifically denotes a common cathode pair in an SOT-23 package, widely used in consumer and automotive electronics for signal processing and protection tasks.

Single Diodes Replacement Considerations

Direct substitutes include BAS7004E6433HTMA1. Verify pinout compatibility and electrical parameters such as reverse voltage and forward current when selecting alternatives. Check if the substitute meets the same AEC-Q101 automotive qualification if required for the application.
