1N4469E3/TR

Single Zener Diodes Overview

The Microchip Technology 1N4469E3/TR is a commercial-grade, hermetically sealed glass Zener diode with a nominal voltage of 15.0 V and a standard tolerance of ±5%. It operates within a junction temperature range of -65°C to +175°C and features a maximum steady-state power dissipation of 1.5 W at a lead temperature of +112°C. The device utilizes a DO-41 axial-lead package with internal metallurgical bonds and void-less hard glass construction.

Single Zener Diodes Feature Summary

• Hermetically sealed void-less glass package with tungsten slugs for robust construction
• Triple-layer passivation and internal Category 1 metallurgical bonds
• Non-sensitive to electrostatic discharge per MIL-STD-750 method 1020
• Inherently radiation hard

Single Zener Diodes Applications

• High-reliability applications where failure cannot be tolerated
• Voltage regulation over broad operating current and temperature ranges
• Military and aerospace circuits requiring hermetic sealing

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm RoHS compliance status and tolerance level. Ensure the procurement documentation explicitly references the commercial grade specifications and the correct JEDEC registration series for the 1N4469 part number.

Single Zener Diodes Selection Notes

Select this component when a 1.5 W power rating and hermetic sealing are required for high-reliability environments. Confirm that the 15.0 V nominal breakdown voltage aligns with circuit requirements and verify compatibility with the DO-41 axial-lead mounting terminals.

Single Zener Diodes Part Context

This component belongs to the 1N4460 through 1N4496 series of 1.5 Watt glass Zener diodes. These devices are industry-recognized regulators available in various voltages from 3.3 to 200 volts. The series is designed for demanding applications requiring robust physical construction and stable electrical performance.

Single Zener Diodes Replacement Considerations

Compatible replacements include other 1N4469 variants from qualified manufacturers or equivalent parts within the 1N4460–1N4496 series that meet the same 1.5 W power rating and DO-41 package dimensions.
