Overview
The Microchip Technology 1N3020BUR-1/TR is a surface mount Zener diode in the DO-213AB (MELF) package. It provides a nominal Zener voltage of 10 V with a 5% tolerance at a test current of 25 mA. The device supports a maximum DC power dissipation of 1 W and operates within a junction temperature range of -55 °C to +175 °C. Key electrical characteristics include a maximum reverse leakage current of 10 µA, a dynamic impedance of 7 Ohms, and a voltage temperature coefficient of 0.076 %/°C.
Feature Summary
- Hermetically sealed glass MELF construction for high reliability
- Leadless surface mount design suitable for high-density applications
- Metallurgically bonded internal contacts for enhanced thermal performance
Applications
- Voltage regulation over broad operating current and temperature ranges
- High-reliability electronic systems requiring low parasitic components
- Applications necessitating radiation hardness and ESD immunity
Procurement Notes
Verify that the specific ordering suffix matches the required RoHS compliance status and packaging format. Confirm the manufacturer's qualification level against project requirements. Ensure the component meets the specified environmental standards before finalizing procurement orders.
Selection Notes
Select this component when a leadless surface mount Zener diode is required for space-constrained designs. Consider the 1 W power rating and wide temperature range for demanding environments. Verify compatibility with the DO-213AB footprint during PCB layout planning.
Part Context
This part belongs to the 1N3016BUR-1 through 1N3045BUR-1 series of surface mount Zener diodes. These devices serve as leadless equivalents to JEDEC registered 1N3016B-1 through 1N3045B-1 numbers. They are designed to meet MIL-PRF-19500/115 qualifications for military-grade reliability.
Replacement Considerations
Direct replacements include other parts from the 1N3016BUR-1 to 1N3045BUR-1 series. Verify exact voltage and tolerance specifications when substituting.
