1N5264B/TR

Single Zener Diodes Overview

The Microchip Technology 1N5264B/TR is a 0.5 W glass axial-lead Zener diode in the DO-35 package, featuring a nominal voltage of 60 V with ±5% tolerance (suffix B). It operates within a temperature range of -65°C to +175°C and includes a tape-and-reel option indicated by the TR suffix. Key electrical parameters include a maximum reverse current of 44 µA at 44 V, a zener impedance of 44 Ω at 0.25 mA, and a positive temperature coefficient of +0.097 %/°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features hermetically sealed glass axial-lead construction for durability
• Offers minimal capacitance characteristics suitable for high-frequency applications
• Inherently radiation hard per MicroNote 050

Single Zener Diodes Applications

• Voltage reference circuits requiring stable breakdown voltage
• Overvoltage protection in sensitive electronic systems
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify that the part number includes the TR suffix to confirm tape-and-reel packaging rather than bulk supply. Ensure the B suffix is present to guarantee the specified ±5% voltage tolerance. Confirm RoHS compliance status if required by assembly specifications, as standard versions may differ from e3 variants.

Single Zener Diodes Selection Notes

Select this component when a precise 60 V regulation point is needed in a compact axial-lead form factor. The low leakage current and defined impedance make it suitable for precision references. Consider thermal derating curves if operating near the upper temperature limit or under continuous high-power conditions.

Single Zener Diodes Part Context

This device belongs to the 1N5221 through 1N5281B series of 0.5 W Zener diodes. It shares the same DO-35 glass package and general electrical testing standards as other members of this family, differing primarily in its specific nominal breakdown voltage and associated impedance values.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available in the MLL5264B DO-213AA MELF style package. Verify pinout compatibility and thermal management requirements when transitioning between axial-lead and surface-mount technologies.
