1N5263B/TR

Single Zener Diodes Overview

The Microchip Technology 1N5263B/TR is a Zener diode with a nominal voltage of 56 V and a power dissipation rating of 0.5 W. It features a DO-35 glass axial-lead package and operates within a temperature range of -65°C to +175°C. The device provides a standard tolerance of ±5%, indicated by the 'B' suffix, and includes an internal bond option denoted by the '-1' suffix. The 'TR' suffix specifies tape and reel packaging compliant with EIA-296 standards.

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
• Inherently radiation hard per MicroNote 050 specifications
• Minimal capacitance characteristics suitable for high-frequency applications

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify that the ordering part number matches the required electrical tolerances and package style. Confirm the presence of specific suffixes such as '-1' for internal bonds or 'e3' for RoHS compliance if environmental regulations apply. Ensure the procurement quantity aligns with the manufacturer's standard tape and reel packaging requirements specified in the datasheet.

Single Zener Diodes Selection Notes

Select this component when a precise 56 V regulation point is needed with tight manufacturing tolerances. The DO-35 package is appropriate for through-hole mounting on printed circuit boards. Consider the thermal resistance and derating curves if the application involves elevated ambient temperatures or continuous high-power operation near the maximum ratings.

Single Zener Diodes Part Context

This device belongs to the popular 1N5221 through 1N5281B series of 0.5 watt Zener Voltage Regulators. The series offers a wide selection of voltages from 2.4 to 200 volts. The 1N5263 variant specifically targets the 56 V segment of this extensive lineup, providing reliable performance for general-purpose regulation tasks in commercial and industrial electronics.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available in the MLL5221 to MLL5281B series using the DO-213AA MELF style package. These variants maintain similar electrical characteristics while offering a different form factor for automated surface mount assembly processes.
