Overview
The Microchip Technology 1N3024BUR-1 is a 1-watt surface mount Zener diode in the DO-213AB (MELF) package. It features a nominal Zener voltage of 15 V with a 5% tolerance, tested at 17 mA. The device exhibits a maximum dynamic impedance of 0.25 Ohms and a maximum reverse leakage current of 10 µA. Qualified per MIL-PRF-19500/115 for JAN reliability levels, it operates within a junction temperature range of -55°C to +175°C.
Feature Summary
- Hermetically sealed glass MELF construction for high-reliability environments
- Metallurgically bonded internal design ensuring low thermal resistance
- Leadless surface mount form factor suitable for high-density packaging
- Inherently radiation hard characteristics
Applications
- Voltage regulation over broad operating current and temperature ranges
- High-density electronic circuit assembly
- Military and aerospace systems requiring MIL-PRF-19500/115 qualification
Procurement Notes
Verify the specific suffix configuration against the datasheet nomenclature to confirm the exact reliability level and RoHS compliance status. Ensure the ordering code matches the required JAN, JANTX, or JANTXV qualification tier. Confirm that the tin/lead or matte-tin terminal finish aligns with the intended assembly process and environmental regulations.
Selection Notes
Select this component when a robust, hermetically sealed Zener diode is required for harsh environments. The DO-213AB package offers a compact footprint compared to axial leads. Consider the 15 V nominal voltage and 5% tolerance for precise reference applications. Evaluate the thermal derating curve if operation exceeds standard ambient temperatures.
Part Context
This part belongs to the 1N3016BUR-1 through 1N3045BUR-1 series of 1-watt surface mount Zener diodes. These devices serve as leadless equivalents to JEDEC registered 1N3016 through 1N3045 numbers. The series provides a wide selection of voltages from 6.8 V to 110 V in a single package outline.
Replacement Considerations
Direct replacements include other 1N3024 variants with matching voltage and tolerance. Verify package compatibility with DO-213AB dimensions. Cross-reference electrical parameters such as dynamic impedance and leakage current to ensure functional equivalence in the target circuit.
