1N5264BUR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N5264BUR-1/TR is a surface mount Zener voltage regulator in the 1N5221BUR-1 through 1N5281BUR-1 series. It provides a nominal Zener voltage of 60 V with a ±5% tolerance at a test current of 2.1 mA. The device operates within a junction temperature range of -65°C to +175°C and dissipates up to 0.5 W. It features a maximum reverse leakage current of 0.1 µA, a dynamic impedance of 170 Ohms, and a positive temperature coefficient of +0.097 %/°C.

Single Zener Diodes Feature Summary

• Hermetically sealed metallurgically bonded glass surface mount package
• Inherently radiation hard per Microsemi specifications
• Non-sensitive to electrostatic discharge (ESD)
• Minimal capacitance characteristics

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• Radiation-hardened electronic circuit designs
• High-reliability surface mount assembly processes

Single Zener Diodes Procurement Notes

Verify that the ordering suffix TR indicates tape and reel packaging as defined by EIA-481-B standards. Confirm RoHS compliance status, as commercial versions may differ from screened MIL-PRF-19500 options. Ensure the specific tolerance level matches the B suffix designation for 5% accuracy requirements during component sourcing.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount equivalent to the axial 1N5264B is required. The DO-213AA package facilitates automated placement while maintaining high thermal stability. Consider the positive temperature coefficient for applications requiring voltage increase with heat, ensuring the 0.5 W power dissipation limit is respected under derating conditions.

Single Zener Diodes Part Context

This part belongs to the 1N5221BUR-1 through 1N5281BUR-1 series, which serves as the surface mount counterpart to the JEDEC registered 1N5221 to 1N5281 axial diodes. Manufactured by Microchip Technology, these devices utilize a metallurgically bonded glass construction. The series covers a wide voltage range from 2.4 V to 200 V, offering various tolerance options including standard 5% and tighter grades.

Single Zener Diodes Replacement Considerations

The 1N5264B is the direct axial leaded equivalent. For parameter-matched replacements within the same manufacturer's portfolio, verify other parts in the 1N5221BUR-1 to 1N5281BUR-1 series that share the DO-213AA package and 60 V nominal rating.
