Overview
The Microchip Technology 1N3041BUR-1/TR is a surface mount Zener diode with a nominal voltage of 75 V and a 5% tolerance. It operates within a junction temperature range of -55 °C to +175 °C and dissipates up to 1.0 W DC power. The device features a DO-213AB (MELF) package, a maximum reverse leakage current of 10 µA at 82 V, and a dynamic impedance of 0.25 Ω at the test current of 175 mA.
Feature Summary
- Hermetically sealed glass MELF construction for high reliability
- Metallurgically bonded internal contacts for low thermal resistance
- Qualified per MIL-PRF-19500/115 standards
Applications
- Voltage regulation in high-density circuit designs
- High-reliability military applications requiring radiation hardness
- Low parasitic requirement environments
Procurement Notes
Verify that the specific ordering suffix matches the required qualification level and RoHS compliance status. Confirm the tape and reel packaging specifications align with automated assembly requirements. Ensure the component meets the necessary environmental operating conditions for the intended deployment.
Selection Notes
Select this component when a leadless surface mount Zener diode is required for high-density layouts. Consider its metallurgically enhanced design for superior reliability compared to standard packages. Verify that the 75 V breakdown voltage and 1 W power dissipation meet the circuit's electrical demands.
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 axial-leaded parts but utilize the DO-213AB outline. The series offers a wide voltage selection from 6.8 V to 110 V with various tolerance options.
Replacement Considerations
Direct replacements include other members of the 1N3016B-1 through 1N3045B-1 series or commercial equivalents in the DO-213AB package. Verify that any substitute maintains the same hermetic seal quality and MIL-PRF-19500/115 qualification if required.
