Single Zener Diodes Procurement Notes

Verify the specific ordering suffix '-7-F' corresponds to the 3000-unit tape and reel packaging format. Confirm that the component meets RoHS compliance standards and utilizes green molding compound if manufactured after date code 0627. Ensure the application environment remains within the specified thermal resistance and power derating limits defined in the datasheet.

Single Zener Diodes Selection Notes

Select this component when a compact surface-mount solution is required for low-voltage regulation near 3.9 V. The SOT-323 package is suitable for space-constrained designs. Consider the 90 Ω impedance and 3.0 µA leakage specifications for circuit sensitivity requirements. Verify compatibility with automated assembly processes utilizing standard SMD placement equipment.

Single Zener Diodes Part Context

This part belongs to the BZX84W series of 200 mW surface mount Zener diodes produced by Diodes Incorporated. The series covers a wide voltage range from 2.4 V to 39 V in the E24 tolerance series. These devices are designed for general-purpose regulation and utilize a plastic SOT-323 case with molded 'Green' compound for environmental compliance.
