Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging quantity and reel specifications. Ensure that the HE3 designation aligns with required RoHS compliance and automotive qualification standards. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a precise 20 V reference or clamp is needed in a compact SMF footprint. Consider the thermal derating curve if operating near the upper temperature limits. Verify that the surge current handling meets the specific application's transient requirements compared to standard Zener alternatives.

Single Zener Diodes Part Context

This part belongs to the BZD27B Series, which provides a wide range of breakdown voltages from 3.6 V to 200 V. The series utilizes a low-profile surface-mount package compatible with SOD-123W outlines. The HE3 variant specifically denotes RoHS compliance and AEC-Q101 qualification, distinguishing it from commercial grade versions.

Single Zener Diodes Replacement Considerations

Check for BZD27B20P-E3-18 for commercial grade equivalents. Verify compatibility with other manufacturers' DO-219AB packages if cross-sourcing is necessary.
