Overview
The Microchip Technology 1N3034BUR-1 is a surface mount Zener diode with a nominal voltage of 39 V and a 5% tolerance. It operates within a junction temperature range of -55 °C to +175 °C and dissipates up to 1 W. The device features a maximum reverse leakage current of 10 µA, a dynamic impedance of 60 Ohms at the test current of 6.5 mA, and a positive temperature coefficient of 0.101 %/°C.
Feature Summary
- Hermetically sealed glass MELF construction for high reliability
- Metallurgically bonded internal design for enhanced stability
- Qualified per MIL-PRF-19500/115 standards
Applications
- Voltage regulation in high-density circuit designs
- High-reliability military and aerospace systems
- Low parasitic requirement applications
Procurement Notes
Verify that the specific part number suffix matches the required military qualification level (JAN, JANTX, or JANTXV) as defined in the manufacturer's nomenclature guide. Confirm RoHS compliance status if applicable, noting that commercial versions may differ from qualified levels. Ensure the ordering documentation explicitly references the DO-213AB package outline.
Selection Notes
Select this component when a leadless surface mount equivalent to the JEDEC registered 1N3034B-1 is required. It is suitable for environments demanding low thermal resistance and inherent radiation hardness. Verify that the mounting surface system Coefficient of Expansion matches the device's axial expansion rate of approximately +6 PPM/°C.
Part Context
This device belongs to the 1N3016BUR-1 through 1N3045BUR-1 series, which provides surface mount alternatives to traditional axial-leaded components. Manufactured by Microsemi (now Microchip Technology), these diodes utilize a DO-213AB (MELF) package to facilitate automated assembly while maintaining hermetic sealing capabilities.
Replacement Considerations
The 1N3034B-1 serves as the direct JEDEC registered axial-leaded counterpart. For surface mount replacements, verify compatibility within the broader 1N3016BUR-1 to 1N3045BUR-1 family based on exact voltage and tolerance requirements.
