1N3020BUR-1

Overview

The Microchip Technology 1N3020BUR-1 is a surface mount Zener diode in the DO-213AB (MELF) package. It provides a nominal Zener voltage of 10 V with a 5% tolerance at a test current of 25 mA. The device features a maximum reverse leakage current of 10 µA and a dynamic impedance of 7 Ohms. It operates within a junction temperature range of -55 °C to +175 °C and dissipates up to 1 W of power.

Feature Summary

• Hermetically sealed glass MELF construction for high reliability
• Leadless surface mount design suitable for high-density applications
• Metallurgically bonded internal contacts for enhanced thermal performance

Applications

• Voltage regulation over broad operating currents
• High-reliability military and aerospace circuits
• Low parasitic requirement surface mount designs

Procurement Notes

Verify the specific suffix requirements against the MIL-PRF-19500/115 standard. Confirm RoHS compliance status as commercial versions differ from qualified levels. Ensure the ordering nomenclature matches the required voltage tolerance and qualification level before finalizing procurement.

Selection Notes

Select this component when a leadless surface mount equivalent to the JEDEC registered 1N3020B-1 is required. Consider the DO-213AB outline for low parasitic needs. Evaluate the metallurgically enhanced internal construction for applications demanding lower thermal resistance and greater reliability compared to standard packages.

Part Context

This part belongs to the 1N3016BUR-1 through 1N3045BUR-1 series, which are surface mountable Zener diodes. The series offers a Zener voltage range from 6.8 volts to 110 volts. These devices serve as leadless equivalents to the JEDEC registered 1N3016 through 1N3045 number series in the DO-13 package.

Replacement Considerations

The 1N3020B-1 is the JEDEC registered axial-leaded equivalent. Verify package compatibility when substituting between DO-213AB and DO-41 formats.
