Single Zener Diodes Procurement Notes

Verify the specific suffix (e.g., /TR) against the datasheet to confirm packaging format, as standard bulk and tape-and-reel variants exist within this family. Ensure the required Zener voltage tolerance aligns with the ±5% specification provided for the base part number. Confirm that the DO-213AA-2 footprint matches the target PCB layout constraints before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed, high-temperature capable Zener diode is required for surface mount assembly. The 39 V rating suits mid-range voltage regulation needs. Consider the 500 mW power dissipation limit for thermal management. Verify compatibility with existing JEDEC 1N47xx series designs if replacing through-hole components with surface mount equivalents.

Single Zener Diodes Part Context

This device belongs to Microchip's line of surface mount Zener diodes, serving as the SMD counterpart to the traditional 1N4678 through 1N4717 series. It utilizes the DO-213AA-2 package, which provides a compact form factor while maintaining hermetic sealing. The product line emphasizes reliability and stability for industrial and commercial applications requiring precise voltage references.

Single Zener Diodes Replacement Considerations

Direct replacements include other manufacturers' DO-213AA-2 packaged Zener diodes with identical 39 V nominal voltage and ±5% tolerance. Ensure substitute parts meet the same 500 mW power dissipation and -65 °C to +175 °C operating temperature range specifications.
