1N3016BUR-1/TR

Overview

The 1N3016BUR-1 is a surface mount Zener diode with a nominal voltage of 6.8 V at a test current of 37 mA. It operates within a junction temperature range of -55 °C to +175 °C and dissipates up to 1.0 W DC power. The device features a maximum reverse leakage current of 150 µA at 5.2 V, a dynamic impedance of 3.5 Ohms at the test point, and a temperature coefficient of 0.061 %/°C. Packaged in a DO-213AB MELF outline, it offers hermetic sealing for high-reliability applications.

Feature Summary

• Hermetically sealed glass construction with metallurgically bonded internal contacts
• Leadless surface mount design suitable for high-density mounting
• Qualified per MIL-PRF-19500/115 standards

Applications

• Voltage regulation over broad operating current and temperature ranges
• High-reliability electronic systems requiring radiation hardness
• Low parasitic requirement circuit designs

Procurement Notes

Verify that the specific ordering suffix matches the required reliability level (JAN, JANTX, or JANTXV) and RoHS compliance status. Confirm package dimensions align with the DO-213AB MELF outline. Ensure thermal management accounts for the linear derating curve starting at 125 °C end cap temperature. Check soldering parameters against MIL-STD-750 method 2026 requirements.

Selection Notes

Select this component when a leadless surface mount equivalent to the JEDEC registered 1N3016 series is required. Consider the 6.8 V nominal voltage and 37 mA test current for biasing conditions. Evaluate the 0.061 %/°C temperature coefficient for precision stability needs. Verify compatibility with the Axial Coefficient of Expansion of approximately +6 PPM/°C for the mounting surface system.

Part Context

This device belongs to the 1N3016B-1 through 1N3045B-1 series, which are surface mountable versions of JEDEC registered diodes. The series covers a Zener voltage range from 6.8 volts to 110 volts. It serves as a direct replacement for axial-leaded counterparts while providing improved mechanical robustness and lower thermal resistance through its metallurgically enhanced contact design.

Replacement Considerations

Direct leadless surface mount equivalents exist for the JEDEC registered 1N3016 through 1N3045 number series. Lower voltage options in the same package include the 1N3821AUR-1 through 1N3828AUR-1 series.
