1N4465DUS

Single Zener Diodes Overview

The Microchip Technology 1N4465DUS is a surface mount Zener voltage regulator with a nominal breakdown voltage of 10.0 V and a maximum dynamic impedance of 5 Ohms at the test current of 25.0 mA. It features a 1% tolerance designation, a maximum continuous current of 143 mA, and a surge current rating of 1.4 A. The device operates within a junction temperature range of -65°C to +175°C and dissipates up to 1.5 W of steady-state power.

Single Zener Diodes Feature Summary

• Hermetically sealed voidless glass construction using internal metallurgical bonds for robust reliability.
• Qualified per MIL-PRF-19500/406 standards for high-reliability applications where failure cannot be tolerated.
• Inherently radiation hard and non-sensitive to electrostatic discharge (ESD) per MIL-STD-750 method 1020.

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges.
• High-reliability military and aerospace electronic systems.
• Radiation-hardened circuit protection designs.

Single Zener Diodes Procurement Notes

Verify the specific suffix 'D' indicates the 1% tolerance level as defined in the part nomenclature section. Confirm that the ordering information matches the required military qualification level and package type. Ensure compatibility with RoHS requirements if applicable, noting that compliance may vary by grade.

Single Zener Diodes Selection Notes

Select this component when a precise 10.0 V reference is required with tight 1% tolerance constraints. Consider the 1.5 W power dissipation capability and the D-5A MELF package dimensions for PCB layout. Evaluate thermal resistance characteristics against the expected ambient operating conditions.

Single Zener Diodes Part Context

This device belongs to the 1N4460US through 1N4496US series of voidless hermetically sealed surface mount Zener diodes. The series offers selections from 3.3 to 200 volts with standard 5% tolerance, while tighter tolerances are available via specific ordering suffixes.

Single Zener Diodes Replacement Considerations

Equivalent parts include JAN1N4465CUS and JANTX1N4465CUS. Verify that substitute components maintain the same 1% tolerance specification and MIL-PRF-19500/406 qualification status.

Single Zener Diodes FAQ

What does the 'D' suffix indicate in the 1N4465DUS part number?

The 'D' suffix designates a voltage tolerance of plus or minus 1%, compared to the standard 5% tolerance found on devices without a suffix.

Is the 1N4465DUS sensitive to electrostatic discharge?

No, the device is non-sensitive to ESD per MIL-STD-750 method 1020.
