JAN1N3025D-1/TR

Single Zener Diodes Overview

The JAN1N3025D-1/TR is a hermetically sealed Zener diode in the glass DO-41 package, qualified per MIL-PRF-19500/115. It provides a nominal Zener voltage of 16 V at a test current of 15.5 mA with a tight tolerance of 1%. The device features a maximum dynamic impedance of 16 Ohms and operates within a temperature range of -55°C to +175°C. It dissipates up to 1 W of power and includes metallurgically bonded tungsten slugs for thermal management.

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required qualification level and packaging format. Confirm RoHS compliance status as it varies by grade. Ensure the specific tolerance code aligns with circuit requirements. Check datasheet revisions for updated mechanical dimensions. Validate supplier documentation against official Microchip specifications.

Single Zener Diodes Selection Notes

Select this component when strict voltage accuracy and radiation hardness are required. The 1% tolerance ensures precise regulation compared to standard commercial variants. Verify thermal derating curves if operating near maximum power dissipation limits. Consider the axial lead configuration for through-hole mounting constraints.

Single Zener Diodes Part Context

This part belongs to the established 1N3016B-1 through 1N3045B-1 series registered with JEDEC. It shares the same physical package and core electrical characteristics as other members of the family, differing primarily in breakdown voltage and tolerance codes. The JAN prefix indicates a specific military reliability qualification level.

Single Zener Diodes Replacement Considerations

Compatible substitutes include JANTXV1N3025D-1 and JAN1N3025B-1 from the same manufacturer. These alternatives share identical package dimensions and basic electrical parameters but differ in reliability qualification levels or voltage tolerances.
