1N4464D

Single Zener Diodes Overview

The Microchip Technology 1N4464D is a through-hole Zener diode designed for voltage regulation. It features a nominal Zener voltage of 13V with an impedance of 8 Ohms. The component utilizes a DO-41 glass package and operates within a temperature range of -65°C to +175°C junction temperature.

Single Zener Diodes Feature Summary

• Hermetically sealed void-less glass construction
• Military qualification per MIL-PRF-19500/406
• High-reliability metallurgical bonding

Single Zener Diodes Applications

• Military-grade voltage regulation circuits
• High-reliability power supply protection
• Avionics control systems

Single Zener Diodes Procurement Notes

Verify the specific grade suffix (e.g., JAN, JANTX, JANS) required for your application, as reliability levels vary. Confirm that the standard commercial 1N4464D variant meets your environmental specifications if military qualification is not mandatory. Check current availability status due to restricted supply conditions.

Single Zener Diodes Selection Notes

Select this component when a 13V reference is needed in a ruggedized environment. Ensure the circuit design accommodates the 8 Ohm impedance at the operating current. Verify thermal management requirements given the wide operating temperature range up to 175°C junction temperature.

Single Zener Diodes Part Context

This part belongs to the 1N4460–1N4496 series of 1.5-watt Zener diodes. These devices are industry-recognized regulators suitable for applications where failure cannot be tolerated. The series offers various voltage selections with standard 5% tolerance options.

Single Zener Diodes Replacement Considerations

Equivalent parts include JANS1N4464D and JANTXV1N4464D for higher reliability grades. Commercial equivalents may lack hermetic sealing.
