1N3018BUR-1

Overview

The Microchip Technology 1N3018BUR-1 is a surface mount glass Zener diode in the DO-213AB package. It provides an 8.2 V nominal voltage with a ±5% tolerance at a test current of 31 mA. The device supports a maximum power dissipation of 1.5 W and operates within a temperature range of -65°C to +175°C. Key electrical characteristics include a maximum reverse leakage current of 5 µA, a typical temperature coefficient of 0.048 %/°C, and a maximum Zener impedance of 4.5 Ω.

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

Applications

• High-reliability applications requiring hermetic sealing
• High-density circuit board mounting
• Voltage regulation over broad operating currents and temperatures

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm compliance requirements. Confirm that the component meets RoHS standards if required by the application. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee authenticity and traceability.

Selection Notes

Select this component when a surface mount solution is needed to replace axial lead equivalents while maintaining higher power ratings. Consider the low leakage current and tight voltage tolerances for precision regulation tasks. Evaluate the thermal resistance specifications to ensure adequate heat dissipation within the target enclosure constraints.

Part Context

This part belongs to the 1N3016BUR-1 through 1N3051BUR-1 series of surface mountable Zener diodes. These devices are designed as equivalents to JEDEC registered 1N3016 through 1N3051 parts but utilize the DO-213AB outline instead of the DO-13 package. The series offers a wide voltage selection ranging from 6.8 to 200 volts.

Replacement Considerations

Equivalent axial lead versions are available as 1N3016B through 1N3051B. Devices with MQ, MX, or MV prefixes offer screening equivalent to JAN, JANTX, or JANTXV standards.
