Procurement Notes

Verify that the ordering code matches the specific suffix requirements for automotive grade qualification and tape packaging. Confirm RoHS compliance status and material categorization details directly with the manufacturer before finalizing procurement orders to ensure alignment with project specifications.

Selection Notes

Select this component when a dual Zener array with tight ±2% voltage tolerance is required for automotive environments. Ensure the application operates within the -55 °C to +150 °C junction temperature range and respects the 500 mW power dissipation limit based on the thermal resistance values provided in the datasheet.

Part Context

This part belongs to the Vishay AZ23 series of small signal Zener diodes. The 'B' designation indicates the tighter ±2% voltage tolerance compared to the standard ±5% 'C' grade. The 'HE3_A' suffix denotes the AEC-Q101 qualified, lead-free variant packaged in taped reels for automated assembly processes.
