Single Zener Diodes Procurement Notes

Verify the specific ordering code suffix to confirm the reel size and tape configuration required for your assembly line. Ensure that the procurement documentation explicitly states AEC-Q101 qualification status, as this designation applies specifically to the HE3 variant. Cross-reference the manufacturer part number with official Vishay databases to validate compliance with RoHS3 directives before finalizing orders.

Single Zener Diodes Selection Notes

Select this component when a precise 2.4 V reference is required in a compact surface-mount footprint. The low voltage rating necessitates careful consideration of the high dynamic resistance compared to higher voltage variants. Verify that the application circuit can accommodate the specified reverse leakage current and thermal constraints inherent to the SOD-123 package geometry.

Single Zener Diodes Part Context

This device belongs to the BZT52 series of small signal Zener diodes designed for general-purpose applications. The series offers a wide working voltage range from 2.2 V to 75 V according to the E24 standard. The HE3 suffix indicates a lead-free, halogen-free, and RoHS-compliant product that meets automotive qualification requirements.
