1N3046BUR-1

Single Zener Diodes Overview

The Microchip Technology 1N3046BUR-1 is a surface mount glass Zener diode in the DO-213AB outline, rated for 1.5 watts power dissipation at 25°C. It provides a nominal Zener voltage of 120 V with a test current of 2.0 mA and a maximum impedance of 550 Ohms. The device operates within a temperature range of -65°C to +175°C and features a hermetically sealed glass MELF package.

Single Zener Diodes Feature Summary

• Hermetically sealed double-slug glass construction for high-reliability applications
• 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-density circuit board mounting
• High-reliability electronic systems
• Voltage regulation over broad operating currents and temperatures

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm screening levels and compliance options. Confirm that the component matches the required JEDEC registration parameters and thermal characteristics for your specific application environment before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a surface mount solution is required for voltages up to 200 V with a 1.5 W rating. Ensure the PCB footprint aligns with the DO-213AB dimensions and consider the thermal resistance values for steady-state power derating calculations under your expected ambient conditions.

Single Zener Diodes Part Context

This part belongs to the 1N3016BUR-1 through 1N3051BUR-1 series, which are surface mount equivalents to the axial lead 1N3016B through 1N3051B devices. The series offers a wide voltage selection from 6.8 to 200 volts while maintaining the reliability benefits of glass hermetic sealing in a compact form factor.

Single Zener Diodes Replacement Considerations

Equivalent axial lead parts include the 1N3046B series. For screened variants, prefixes such as MQ, MX, or MV may be used to denote JAN, JANTX, or JANTXV screening levels respectively.
