1N3035BUR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N3035BUR-1/TR is a surface mount Zener diode in the DO-213AB (MELF) package. It provides a nominal Zener voltage of 43 V with a 5% tolerance at a test current of 6 mA. The device features a maximum dynamic impedance of 70 Ohms and a maximum reverse leakage current of 10 µA. It supports a DC power dissipation of 1 W, operating within a junction temperature range of -55 °C to +175 °C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass MELF construction for high reliability
• Leadless surface mount design suitable for high-density applications
• Metallurgically bonded internal contacts to reduce thermal resistance

Single Zener Diodes Applications

• Voltage regulation over broad operating currents and temperatures
• High-reliability electronic systems requiring low parasitic effects
• Radiation-hardened circuit designs

Single Zener Diodes Procurement Notes

Verify the specific suffix against official documentation to confirm RoHS compliance status and tape-and-reel packaging specifications. Ensure the ordering code matches the required military qualification level if applicable. Confirm that the supplier source aligns with authorized distribution channels for this component series.

Single Zener Diodes Selection Notes

Select this component when a leadless surface mount equivalent to the 1N3035B-1 JEDEC registration is required. It is appropriate for designs needing hermetic sealing and low thermal resistance. Consider the 43 V breakdown characteristic and 1 W power rating for voltage reference or protection circuits.

Single Zener Diodes Part Context

This part belongs to the 1N3016BUR-1 through 1N3045BUR-1 series of 1 Watt Surface Mount Zener Diodes. These devices are qualified per MIL-PRF-19500/115 and serve as surface mount replacements for axial-leaded JEDEC registered numbers in the DO-13 package.

Single Zener Diodes Replacement Considerations

Direct replacement options include the 1N3035B-1 for axial mounting or other variants within the 1N3016BUR-1 to 1N3045BUR-1 series sharing the same package and electrical parameters.
