Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as the datasheet originates from Microsemi Scottsdale Division while the brand is listed as Microchip Technology. Confirm that the standard JEDEC registered part number matches the required specifications without additional military prefixes or suffixes. Ensure the DO-7 package type aligns with the intended through-hole mounting requirements.

Single Zener Diodes Selection Notes

Select this component when a 6.4 V reference with a 0.001%/°C temperature coefficient is required. The 4.0 mA test current setting distinguishes it from lower-current variants in the series. Verify compatibility with the DO-7 axial-leaded package and ensure the operating environment falls within the specified -65°C to +175°C range.
