1N5262A

Single Zener Diodes Overview

The Microchip Technology 1N5262A is a 51 V Zener diode with ±10% voltage tolerance. It operates in the DO-204AH (DO-35) glass axial-lead package and dissipates up to 500 mW at 25°C. The device features a test current of 2.5 mA, a maximum reverse leakage current of 100 nA at 39 V, and a Zener impedance of 125 Ohms. It withstands operating temperatures from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass axial-lead construction
• Regulates voltage across broad operating currents and temperature ranges
• Minimal capacitance characteristics
• Inherently radiation hard

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• General purpose voltage reference applications
• Protection circuits requiring inherent radiation hardness

Single Zener Diodes Procurement Notes

Verify the specific suffix 'A' confirms the required ±10% tolerance level for your design. Confirm the package type matches the DO-35 axial lead form factor. Ensure the manufacturer source aligns with Microsemi or authorized Microchip distributors for JEDEC registered components.

Single Zener Diodes Selection Notes

Select this component when a standard 51 V breakdown voltage with moderate precision is required. The DO-35 package suits through-hole mounting. Consider tighter tolerance variants if stricter voltage limits are necessary.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators. The series provides a wide selection from 2.4 to 200 volts. Standard tolerances include 5% and 10%, while tighter options exist with different suffixes.

Single Zener Diodes Replacement Considerations

Equivalent parts within the same series include 1N5262B for tighter tolerance requirements. Surface mount equivalents are available in the MLL5221 to MLL5281B series using the DO-213AA MELF package.
