Procurement Notes
Verify the specific ordering code suffix against project requirements before procurement. Confirm that the standard 10,000 units per reel packaging aligns with manufacturing needs. Ensure compliance with RoHS3 directives and check for any regional export classifications if applicable to the destination market.
Selection Notes
Select this component when a dual-channel Zener array with a 43 V nominal breakdown is required in a compact SOT-23 footprint. Consider the ±5% tolerance and 97 Ω dynamic resistance for precision requirements. Evaluate thermal management capabilities based on the 300 mW dissipation limit on standard PCB footprints.
