1N3044B-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N3044B-1/TR is a 1-watt glass case Zener diode with a nominal voltage of 100 V and a 5% tolerance. It operates within a junction temperature range of -55°C to +175°C and features a hermetically sealed DO-41 package. The device provides low reverse leakage current, inherent radiation hardness, and non-sensitive ESD characteristics.

Single Zener Diodes Feature Summary

• Hermetically sealed glass DO-41 package for high-reliability applications
• Inherently radiation hard design suitable for harsh environments
• Low reverse leakage currents across broad operating ranges
• Non-sensitive to electrostatic discharge (ESD)

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• High-reliability military and aerospace electronic circuits
• Radiation-hardened power supply designs

Single Zener Diodes Procurement Notes

Verify the specific ordering suffixes required for your application. Confirm whether JAN, JANTX, or JANTXV qualification levels are necessary. Ensure the tape and reel packaging option aligns with your manufacturing equipment specifications before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 100 V Zener voltage with 5% tolerance is required in a through-hole glass package. Consider the 1 W power dissipation rating and thermal derating curves for proper heat management. Verify that the MIL-PRF-19500/115 qualification meets your project's reliability standards.

Single Zener Diodes Part Context

This part belongs to the established 1N3016B-1 through 1N3045B-1 series of 1 Watt Glass Case Zener Diodes. These devices are JEDEC registered and qualified per MIL-PRF-19500/115. They utilize a metallurgically bonded double plug construction within a voidless hard glass case containing tungsten slugs.

Single Zener Diodes Replacement Considerations

Compatible substitutes include JAN1N3044CUR-1 and 1N3044BUR-1 from Microchip Technology. Both alternatives maintain the 100 V specification but differ in package type, utilizing surface mount configurations instead of the through-hole DO-41 format.
