Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging quantity and reel specifications. Ensure compliance with RoHS directives and material categorization requirements relevant to the target region. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.
Selection Notes
Select this component when a dual-channel Zener array with high voltage accuracy is required. The ±2% tolerance distinguishes it from standard ±5% variants. Verify that the 300 mW power dissipation rating aligns with the thermal design constraints of the printed circuit board footprint. Confirm compatibility with surface mount assembly processes utilizing the SOT-23 package dimensions.
Part Context
This device belongs to the AZ23 series of small signal silicon planar Zener diodes. The series offers a wide voltage range from 2.2 V to 75 V. Variants are available with different tolerances and AEC-Q101 automotive qualifications. The base part number structure allows for easy identification of voltage, tolerance, and packaging options within the broader product family.
