1N5258A

Single Zener Diodes Overview

The Microchip Technology 1N5258A is a Zener diode with a nominal voltage of 36 V and a power dissipation rating of 0.5 W at 25°C. It features a maximum reverse current of 100 μA and a maximum Zener impedance of 70 Ω. The device operates within a temperature range of -65°C to +175°C, has a test current of 3.4 mA, and utilizes a hermetically sealed glass DO-35 axial-lead package.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Constructed in a hermetically sealed glass axial-lead package for environmental protection
• Inherently radiation hard per MicroNote 050 specifications

Single Zener Diodes Applications

• Voltage regulation circuits requiring stable reference voltages
• Protection against overvoltage conditions in sensitive electronic components
• Clamping applications in signal processing systems

Single Zener Diodes Procurement Notes

Verify the specific suffix 'A' indicates a 10% voltage tolerance when ordering. Confirm that the component meets RoHS compliance requirements if applicable by checking for the 'e3' designation on the datasheet or packaging. Ensure the manufacturer source matches the official Microsemi/Microchip documentation to guarantee authenticity and electrical parameter accuracy.

Single Zener Diodes Selection Notes

Select this component for applications requiring a 36 V reference point with moderate tolerance. Consider the 0.5 W power dissipation limit and derating curves for thermal management. Evaluate the DO-35 package dimensions for PCB layout compatibility and verify lead length requirements for accurate electrical testing.

Single Zener Diodes Part Context

This part belongs to the 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 1N5258A specifically targets the 36 V segment of this extensive lineup, providing standard tolerance options for general-purpose regulation tasks.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available as MLL5258B in the DO-213AA MELF style package. Direct pin-to-pin replacements may require verification of package footprint differences between axial-lead and surface-mount technologies.
