Single Zener Diodes Procurement Notes

Verify the specific suffix 'E3' indicates RoHS compliance and confirm the 'TR' designation corresponds to tape-and-reel packaging. Ensure the procurement order explicitly matches the full part number to guarantee the correct metallurgical bond and qualification level are delivered.

Single Zener Diodes Selection Notes

Select this component when a 3 V Zener reference is required in harsh environments. The DO-35 package supports through-hole mounting, while the extended temperature rating up to 175 °C accommodates demanding thermal conditions without derating issues.

Single Zener Diodes Part Context

This part belongs to the 1N4614-1 through 1N4627-1 series of 500 mW Zener diodes. These devices are characterized by their internal metallurgical bond and availability in various qualification levels, including JAN, JANTX, JANTXV, and JANS, ensuring suitability for critical systems.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N4619-1 and 1N4619UR-1. Verify that substitute components maintain the same 3 V nominal voltage, 500 mW power rating, and DO-35 package dimensions to ensure mechanical and electrical compatibility.
