Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and variant selection. Confirm that the requested quantity aligns with standard reel or cut-tape availability requirements. Cross-reference the part number with the latest datasheet to validate electrical parameters before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener solution with a common anode topology is required for precise voltage clamping. Ensure the application voltage does not exceed the 30 V rating and that power dissipation limits remain within the 200 mW specification. Consider the SOT-25-5 footprint constraints during PCB layout design to maintain adequate thermal clearance.
Part Context
This component belongs to the FTZ series of Zener diode arrays from ROHM Semiconductor. These devices are engineered for general-purpose voltage regulation tasks in compact electronic assemblies. The series emphasizes reliability and consistent performance across automotive and industrial environments, providing stable reference voltages in minimal form factors.
Replacement Considerations
Consult official substitution lists for compatible dual common anode Zener arrays with matching 30 V ratings and SOT-25-5 footprints. Verify pinout compatibility and electrical parameter equivalence before implementing any alternative components in existing designs.
