1N3045B-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N3045B-1/TR is a 1-watt Zener diode with a nominal voltage of 110 V and ±5% tolerance. It operates in the DO-204AL (DO-41) axial package and features a hermetically sealed glass construction. The device supports a junction temperature range from -55°C to +175°C and includes tape-and-reel packaging for automated assembly.

Single Zener Diodes Feature Summary

• Hermetically sealed glass DO-41 package with metallurgically bonded tungsten slugs
• Qualified per MIL-PRF-19500/115 for high-reliability applications
• Low reverse leakage current characteristics
• Inherently radiation hard

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify that the ordering suffix /TR confirms tape-and-reel packaging, as standard versions may be bulk packed. Confirm RoHS compliance status, as it varies by grade. Ensure the specific JAN, JANTX, or JANTXV qualification level matches project requirements before procurement.

Single Zener Diodes Selection Notes

Select this component for applications requiring a 110 V reference with tight 5% tolerance. The DO-41 package suits through-hole designs. Verify thermal derating curves if ambient temperatures exceed 65°C to ensure power dissipation remains within the 1 W limit.

Single Zener Diodes Part Context

This part belongs to the 1N3016B-1 through 1N3045B-1 series of 1-watt glass case Zener diodes. The series covers voltages from 6.8 V to 110 V. The B suffix indicates a 5% voltage tolerance. The -1 suffix denotes the JEDEC registration number format.
