Overview
The Microchip Technology 1N3027BUR-1 is a surface mount Zener diode with a nominal voltage of 20 V and a test current of 12.5 mA. It features a maximum dynamic impedance of 22 Ohms at the test point and a maximum reverse leakage current of 10 µA. The device operates within a temperature range of -55 °C to +175 °C, dissipating up to 1.0 W of power. It utilizes a DO-213AB (MELF) package and offers a voltage tolerance of 5%.
Feature Summary
- Hermetically sealed glass MELF construction for high reliability
- Metallurgically bonded internal contacts for enhanced durability
- Qualified per MIL-PRF-19500/115 standards
- Leadless surface mount design suitable for high-density applications
Applications
- Voltage regulation in high-reliability circuits
- High-density electronic assemblies requiring low parasitic elements
- Military and aerospace systems demanding radiation hardness
Procurement Notes
Verify that the specific part number matches the required military qualification level (JAN, JANTX, or JANTXV). Confirm RoHS compliance status if applicable, as commercial versions may differ from qualified levels. Ensure the ordering suffix aligns with the desired tape and reel packaging options.
Selection Notes
Select this component when a leadless surface mount equivalent to the JEDEC registered 1N3027B-1 is required. Consider the 1W power dissipation capability and the specific 20V breakdown characteristics. Evaluate the thermal resistance and operating temperature limits against the system's environmental constraints.
Part Context
This device belongs to the 1N3016BUR-1 through 1N3045BUR-1 series of 1 Watt Surface Mount Zener Diodes. It serves as a direct surface mount replacement for the axial-leaded 1N3016B-1 through 1N3045B-1 JEDEC registration numbers, maintaining similar electrical performance in a compact DO-213AB outline.
Replacement Considerations
Direct surface mount equivalents are available for the 1N3027B-1 JEDEC registration. Verify compatibility with existing board layouts due to the DO-213AB package dimensions.
