1N965BUR-1

Single Zener Diodes Overview

The Microchip Technology 1N965BUR-1 is a hermetically sealed Zener diode designed for high-reliability applications. It features a round-end axial leaded glass DO-35 package and operates within an extended temperature range of -65°C to +175°C. The device provides a nominal Zener voltage of 15V with a tight tolerance of ±2%, tested at 8.5mA. Key electrical characteristics include a maximum reverse leakage current of 500nA, a Zener impedance of 16 ohms, and a power dissipation rating of 400mW. It is manufactured in accordance with MIL-PRF-19500/117 standards.

Single Zener Diodes Procurement Notes

Verify the specific suffix BUR-1 against the manufacturer's official datasheet to confirm the exact tolerance class and testing standards. Ensure that the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity and traceability. Confirm compliance with relevant military specifications before finalizing orders.

Single Zener Diodes Selection Notes

Select this component when a stable 15V reference is required in extreme thermal conditions. The ±2% tolerance offers higher precision than standard commercial variants. Consider the axial leaded form factor for through-hole mounting constraints. Evaluate the 400mW power dissipation limit against the expected circuit load to ensure safe operation margins.

Single Zener Diodes Part Context

This part belongs to the 1N965 series of silicon Zener diodes produced under military quality standards. The 'B' suffix indicates a ±2% voltage tolerance, while 'UR' typically denotes specific packaging or processing variations. These diodes are engineered for durability in demanding sectors such as defense and aviation where standard commercial parts may fail.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 15V Zener voltage, ±2% tolerance, and DO-35 hermetic package. Verify equivalent MIL-PRF-19500/117 compliance. Generic commercial equivalents lack the required hermetic sealing and temperature range.
