1N3050B-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N3050B-1/TR is a surface-mount glass Zener diode in the DO-213AB package. It provides a nominal voltage of 180 V with a ±5% tolerance at a test current of 1.4 mA. The device features a maximum reverse leakage current of 0.5 µA and a typical temperature coefficient of 0.136 %/°C. Rated for 1.5 W power dissipation, it operates from -65°C to +175°C. The 'TR' suffix indicates tape-and-reel packaging.

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

• Voltage regulation over broad operating current and temperature ranges
• High-density circuit designs requiring low parasitic requirements
• High-reliability applications utilizing hermetic sealing

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required configuration. Confirm the presence of the 'TR' designation ensures tape-and-reel packaging rather than bulk units. Ensure the specific part number aligns with the intended screening level and RoHS compliance status before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a surface-mount solution is required for voltages up to 200 V. Consider the 1.5 W power rating and DO-213AB footprint for space-constrained layouts. Evaluate the thermal resistance characteristics against the specific PCB copper area available for heat dissipation during steady-state operation.

Single Zener Diodes Part Context

This device belongs to the 1N3016BUR-1 through 1N3051BUR-1 series. It serves as the surface-mount equivalent to the axial lead 1N3016B through 1N3051B JEDEC registered devices. The series offers a wide selection of Zener voltages ranging from 6.8 V to 200 V within the same physical outline.

Single Zener Diodes Replacement Considerations

Equivalent axial lead versions include 1N3050B. Surface-mount equivalents are designated as MLL3050B. Screening prefixes such as MQ, MX, or MV provide military qualification options.
