1N3025BUR-1

Overview

The Microchip Technology 1N3025BUR-1 is a surface mount Zener diode with a nominal voltage of 16 V and a 5% tolerance. It operates within a 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 16 Ohms at the test current of 15.5 mA, and a temperature coefficient of 0.089 %/°C.

Feature Summary

• Hermetically sealed glass MELF package for high-reliability applications
• Metallurgically bonded internal construction for enhanced stability
• Qualified per MIL-PRF-19500/115 standards

Applications

• Voltage regulation in high-density circuit designs
• Low parasitic requirement environments
• High-reliability military and aerospace systems

Procurement Notes

Verify that the specific part number matches the required military qualification level (JAN, JANTX, or JANTXV) as indicated by the prefix. Confirm RoHS compliance status if applicable, noting that commercial versions may differ from qualified levels. Ensure the ordering suffix aligns with the desired termination finish and packaging configuration before finalizing procurement.

Selection Notes

Select this component when a leadless surface mount equivalent to the JEDEC registered 1N3025B-1 is required. The DO-213AB outline provides lower thermal resistance compared to traditional packages. Consider the metallurgically enhanced contact design for improved reliability in demanding operating conditions where standard surface mount options are insufficient.

Part Context

This device belongs to the 1N3016BUR-1 through 1N3045BUR-1 series of 1 Watt Surface Mount Zener Diodes. These components serve as leadless surface mount equivalents to the JEDEC registered 1N3016 through 1N3045 number series. They are designed to meet the surface mount DO-213AB outline while maintaining the performance characteristics of their axial-leaded counterparts.

Replacement Considerations

The 1N3025B-1 is the direct JEDEC registered axial-leaded equivalent.
