1N3046B-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N3046B-1/TR is a surface mount glass Zener diode in the DO-213AB outline, rated for 1.5 Watts power dissipation. It provides a nominal Zener voltage of 120 Volts with a ±5% tolerance (indicated by the 'B' suffix). The device operates at a test current of 2.0 mA and features a maximum Zener impedance of 550 Ohms. It supports an operating temperature range from -65°C to +175°C and includes a tape and reel packaging option.

Single Zener Diodes Feature Summary

• Hermetically sealed double-slug glass construction for high reliability
• Metallurgically enhanced internal contact design for lower thermal resistance
• Leadless surface mount package suitable for high-density mounting
• Inherently radiation hard

Single Zener Diodes Applications

• High-reliability applications requiring hermetic sealing
• High-density circuit board mounting
• Voltage regulation over broad operating currents and temperatures
• Radiation-hardened environments

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required screening level and termination plating. Confirm whether the TR suffix is included for tape and reel packaging or if bulk packaging is intended. Ensure the component meets the necessary MIL-PRF-19500/115 qualification standards if military-grade screening is required for the application.

Single Zener Diodes Selection Notes

Select this component when a 120V Zener voltage with tight tolerance is needed in a surface mount form factor. Consider the 1.5W power rating and low thermal resistance for heat dissipation requirements. Verify compatibility with the DO-213AB footprint and ensure the operating temperature range aligns with the system environment.

Single Zener Diodes Part Context

This part belongs to the 1N3016BUR-1 through 1N3051BUR-1 series of surface mountable Zener diodes. It serves as the surface mount equivalent to the JEDEC registered 1N3016 through 1N3051 axial lead devices, offering similar voltage ranges but with a higher power rating and leadless package design.

Single Zener Diodes Replacement Considerations

Equivalent axial lead versions are available in the 1N3016B through 1N3051B series. Surface mount alternatives within the same family include parts like 1N3045BUR-1 or 1N3047BUR-1 for different voltage ratings.
