1N5269/TR

Single Zener Diodes Overview

The Microchip Technology 1N5269/TR is a single Zener diode designed for voltage regulation applications. It features an 87 V nominal Zener voltage with a ±10% tolerance and a maximum power dissipation of 500 mW. The device utilizes a DO-204AH (DO-35) axial through-hole package. Key electrical characteristics include a maximum Zener impedance of 370 Ohms, a reverse leakage current of 100 nA at 68 V, and a forward voltage of 1.5 V at 200 mA. It operates within a junction temperature range of -65°C to 175°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation with an 87 V nominal breakdown voltage.
• Capable of handling 500 mW power dissipation in a compact axial leaded package.
• Engineered for high-temperature operation up to 175°C junction temperature.

Single Zener Diodes Applications

• Voltage reference circuits requiring precise 87 V levels
• Overvoltage protection for sensitive electronic components
• Clamping applications in analog signal processing

Single Zener Diodes Procurement Notes

Verify the specific suffix /TR indicates tape and reel packaging when sourcing. Confirm RoHS compliance status as historical data suggests potential non-compliance for this series. Ensure the supplier provides official Microchip documentation to validate the part number and manufacturing origin before procurement.

Single Zener Diodes Selection Notes

Select this component when an 87 V Zener voltage is required in a standard DO-35 axial package. Consider the 370 Ohm impedance value for dynamic regulation requirements. Verify that the 500 mW power rating aligns with the thermal design of the target application environment.

Single Zener Diodes Part Context

This part belongs to the 1N5269 family of Zener diodes manufactured by Microchip Technology. It shares the same die and electrical specifications as the bulk-packaged 1N5269 but differs in shipping configuration. The /TR suffix specifically denotes tape and reel packaging suitable for automated assembly processes.

Single Zener Diodes Replacement Considerations

Public confirmed substitutes include 1N5269 and 1N5269B from Microchip Technology. These parts offer parameter equivalence but may differ in packaging type or tolerance class. Verify mechanical fit and electrical tolerances before substitution.
