Single Zener Diodes Procurement Notes

Verify the specific voltage rating required, as the 1N3993 series spans 3.9V to 200V. Confirm if military qualifications (JAN/JANTX/JANTXV) are necessary for the application, as commercial versions may differ. Check datasheets for polarity options and package specifications before ordering to ensure compatibility with existing designs.

Single Zener Diodes Selection Notes

Select this component when high power dissipation up to 10 watts is required. Consider the hermetic seal for harsh environments. Evaluate the need for military qualification levels against cost constraints. Ensure the chosen voltage value falls within the specified 3.9V to 200V range for the series.

Single Zener Diodes Part Context

This part belongs to the 1N2970B through 1N3015B and 1N3993A through 1N3998A series of 10W Zener diodes manufactured by Microchip Technology. These components are JEDEC registered and offer a wide range of regulation voltages suitable for various power management tasks.

Single Zener Diodes Replacement Considerations

Consult factory documentation for surface mount equivalents. Verify exact voltage tolerance and temperature coefficients when substituting with other 10W Zener diodes from different manufacturers.
