Single Zener Diodes Procurement Notes

Verify the specific suffix HE3-08 to confirm lead-free compliance and tape-and-reel packaging configuration. Confirm current manufacturing status as some variants in this series may be discontinued. Ensure the ordering part number matches the required 18 V specification and ±2% tolerance class before procurement.

Single Zener Diodes Selection Notes

Select this component when strict voltage accuracy is required alongside automotive qualification. The SOD-323 package suits high-density PCB layouts. Verify that the 200 mW power rating aligns with the expected operating current and thermal environment of the target application circuit.

Single Zener Diodes Part Context

This device belongs to the BZX384 series of low-power voltage regulator diodes. The 'B' designation indicates the ±2% tolerance range, distinguishing it from the wider ±5% tolerance 'C' series. The HE3 suffix denotes Halogen-Free and RoHS-compliant construction within the standard SOD-323 form factor.
