1N5268BE3

Single Zener Diodes Overview

The Microchip Technology 1N5268BE3 is a 0.5 W glass axial-lead Zener diode with an 82 V nominal voltage and ±5% tolerance. It operates within a -65°C to +175°C temperature range, featuring a maximum reverse leakage current of 100 µA at 59 V and a maximum Zener impedance of 330 Ω at the test current of 1.5 mA.

Single Zener Diodes Feature Summary

• Hermetically sealed DO-35 glass package for environmental protection
• Inherently radiation hard per MicroNote 050
• ESD nonsensitive per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Voltage regulation in broad operating current ranges
• Reference voltage generation in precision circuits
• Overvoltage protection in electronic systems

Single Zener Diodes Procurement Notes

Verify that the part number includes the 'e3' suffix to confirm RoHS compliance. Ensure the specific B suffix is present to guarantee the required ±5% voltage tolerance. Confirm the manufacturer origin as Microsemi or Microchip Technology to match the specified electrical characteristics and screening levels.

Single Zener Diodes Selection Notes

Select this component when a standard 82 V reference is needed in a through-hole axial configuration. The 0.5 W power rating supports steady-state operation up to 50°C lead temperature. Consider tighter tolerance variants if stricter voltage limits are required.

Single Zener Diodes Part Context

This device belongs to the JEDEC registered 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators. The series provides a wide selection from 2.4 to 200 volts in standard 5% or 10% tolerances, utilizing a robust glass axial-leaded DO-35 package.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N5268 (standard tolerance) and 1N5268B (5% tolerance). Surface mount equivalents are available in the MLL5221 to MLL5281B series.
