Single Zener Diodes Feature Summary

• Military qualified per MIL-PRF-19500/127 for JAN, JANTX, and JANTXV levels
• Hermetically sealed axial-lead glass DO-35 package with internal metallurgical bond
• Non-sensitive to electrostatic discharge (ESD) per MIL-STD-750 method 1020
• Inherently radiation hard

Single Zener Diodes Applications

• Voltage regulation over broad temperature and current ranges
• High-reliability aerospace and defense electronics
• Radiation-hardened circuit protection

Single Zener Diodes Procurement Notes

Verify the specific qualification level required, as the base part number covers commercial through JANTXV grades. Confirm RoHS compliance status if applicable, noting that this suffix typically indicates non-RoHS compliant versions available for military specifications. Ensure the ordering suffix matches the exact JEDEC type and tolerance requirements defined in the datasheet nomenclature.

Single Zener Diodes Selection Notes

Select this component when a 2.7 V reference is needed in harsh environments requiring high thermal stability and radiation hardness. The DO-35 package supports through-hole mounting, while surface mount alternatives exist with different suffixes. Consider the negative temperature coefficient for low-voltage Zener applications and verify power derating curves for PCB-mounted operations.

Single Zener Diodes Part Context

This component belongs to the 1N4370A-1 through 1N4372A-1 series of 500 mW Zener diodes. These devices are JEDEC registered and offer nominal voltages from 2.4 V to 3.0 V with standard 5% tolerance. The series provides flexible axial-lead terminals and is designed for applications demanding robust performance under extreme thermal conditions.

Single Zener Diodes Replacement Considerations

Equivalent parts include 1N4371A and 1N747A-1. Verify package compatibility and electrical characteristics such as impedance and leakage current before substitution.
