1N5269A

Single Zener Diodes Overview

The Microchip Technology 1N5269A is a 0.5 W glass axial-lead Zener diode housed in a DO-35 (DO-204AH) package. It provides an 87 V nominal Zener voltage with a ±10% tolerance. The device operates within a temperature range of -65°C to +175°C and features a maximum reverse leakage current of 100 nA at 68 V. Its maximum Zener impedance is 370 Ohms, and it exhibits a positive voltage temperature coefficient of +0.099 %/°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole integration
• Constructed with a hermetically sealed glass body for environmental protection

Single Zener Diodes Applications

• Voltage reference circuits requiring high stability
• Overvoltage protection stages in electronic systems
• General-purpose voltage regulation tasks

Single Zener Diodes Procurement Notes

Verify the specific suffix 'A' to confirm the required ±10% tolerance level. Ensure the procurement specification matches the DO-35 axial lead form factor. Confirm that the manufacturer's RoHS compliance status aligns with project requirements, as this series may have non-compliant variants.

Single Zener Diodes Selection Notes

Select this component when an 87 V breakdown voltage is specifically required. The ±10% tolerance suits applications where tighter precision is not critical. Verify that the 370 Ohm dynamic impedance meets the circuit's noise and regulation constraints.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5 W Zener diodes. The series covers a wide voltage selection from 2.4 V to 200 V. Variants are available with different tolerance suffixes, including B for ±5%, C for ±2%, and D for ±1%. The standard JEDEC registration ensures industry compatibility.

Single Zener Diodes Replacement Considerations

Direct parameter-equivalent substitutes include the 1N5269, 1N5269/TR, and 1N5269B.
