- General-purpose voltage regulation in high-reliability equipment
Procurement Notes
Verify the specific suffix HB0G confirms AEC-Q101 qualification and DO-204AL packaging when sourcing. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Ensure the procurement channel provides valid traceability documentation required for automotive or industrial supply chains. Cross-reference the full part number to distinguish from standard commercial grade variants lacking automotive certification.
Selection Notes
Select this component when automotive qualification and high-temperature operation are mandatory requirements. The 27 V breakdown voltage suits specific reference needs, while the 1 W rating allows handling moderate surge currents. Compare against standard 1N4750A parts if AEC-Q101 certification is not required for the application. Ensure the DO-204AL footprint matches the PCB design constraints.
Part Context
This component belongs to the 1N4750 series of Zener diodes produced by Taiwan Semiconductor Corporation. The HB0G suffix specifically denotes the automotive-grade variant compliant with AEC-Q101, distinguishing it from commercial equivalents. It utilizes the standard DO-204AL axial package, ensuring compatibility with existing through-hole manufacturing processes and legacy designs requiring robust voltage regulation.
