Procurement Notes

Verify the specific suffix designation against official Nexperia documentation to confirm compliance status and packaging details. Ensure the selected variant matches the required RoHS and REACH regulatory standards for your target market. Confirm package dimensions and pinout compatibility during the design-in phase to prevent assembly errors.

Selection Notes

Select this component when space-constrained designs require dual diode functionality in a minimal footprint. The SOT-323 package offers a balance between thermal performance and board area efficiency. Consider the 100 V rating and 150 mA current limit to ensure adequate headroom for the intended application signals and load conditions.

Part Context

This component belongs to the Nexperia BAV99 series of small-signal switching diodes. The series provides reliable performance for general electronic applications requiring fast response times. The ZLF suffix typically indicates lead-free manufacturing compliant with international environmental directives, aligning with broader industry shifts toward sustainable production methods.

Replacement Considerations

Compatible substitutes include the BAV99W,115 and BAV99W,135 variants from Nexperia, which share identical electrical specifications and SOT-323 packaging. Verify pinout orientation and thermal characteristics before finalizing any cross-reference substitution.
