1N3051B-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N3051B-1/TR is a surface mount glass Zener diode with a nominal voltage of 200 V and a maximum power dissipation of 1.5 W at 25°C. It features a DO-213AB (SMB) outline, operates from -65°C to +175°C, and has a typical temperature coefficient of 0.100 %/°C. The device includes a 1500 Ohm maximum impedance at the test current of 1.2 mA.

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

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• High-reliability applications requiring hermetic sealing
• High-density circuit board mounting

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'TR' corresponds to tape and reel packaging as specified in the datasheet. Confirm the specific screening level required, noting that standard devices do not include MIL-PRF-19500/115 qualifications unless prefixed with MQ, MX, MV, or MSP. Ensure compatibility with RoHS compliant plating if applicable.

Single Zener Diodes Selection Notes

Select this component when a 200 V Zener voltage is required in a surface mount form factor. Consider the 1.5 W power rating and the low thermal resistance provided by the end-cap mounting. Verify that the 0.100 %/°C temperature coefficient meets the stability requirements of the target application.

Single Zener Diodes Part Context

This part belongs to the 1N3016BUR-1 through 1N3051BUR-1 series, which are surface mount equivalents to the JEDEC registered axial lead 1N3016B through 1N3051B. The series offers a wide voltage selection from 6.8 to 200 volts in a hermetically sealed glass MELF package.

Single Zener Diodes Replacement Considerations

Equivalent axial lead parts include the 1N3051B series. For surface mount replacements within the same family, verify voltage and power ratings against other members of the 1N30xxBUR-1 series.
