Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm tape-and-reel specifications and minimum order quantities. Ensure that the component meets RoHS compliance requirements as defined in the product material categorization guidelines before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener array with a 15 V nominal breakdown is required in a small footprint. Consider the ±5% tolerance and 300 mW power rating relative to the thermal environment. Verify that the SOT-23 package dimensions align with the target PCB layout constraints.
Part Context
This part belongs to the AZ23 series of small signal Zener diodes from Vishay. The series offers various voltage grades according to the E24 standard, packaged in SOT-23 housings. The 'E3' suffix indicates RoHS compliance, while the '-18' suffix specifies the 10,000-unit reel packaging format.
