1N5270/TR

Single Zener Diodes Overview

The Microchip Technology 1N5270/TR is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 91V with a tolerance of ±5% and a power dissipation rating of 500mW (0.5W). The device utilizes a DO-204AH (DO-35) axial leaded package, constructed with hermetically sealed glass encapsulation. Key electrical characteristics include a maximum reverse leakage current of 0.1µA and a maximum forward voltage of 1.5V. It operates within a temperature range extending up to +175°C junction temperature.

Single Zener Diodes Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm compliance status and exact tolerance grades. Ensure the procurement channel provides traceable component history. Cross-reference the package code DO-204AH with PCB footprint requirements. Confirm thermal management capabilities align with the 175°C maximum operating temperature specification for the intended application environment.

Single Zener Diodes Selection Notes

Select this component when a precise 91V regulation point is required in through-hole designs. Consider the 500mW power limit under ambient conditions. Evaluate the ±5% tolerance against circuit sensitivity requirements. Compare the axial form factor against space constraints relative to surface-mount alternatives. Verify compatibility with existing assembly processes for glass-encapsulated devices.

Single Zener Diodes Part Context

This part belongs to the standard 1N52xx series of Zener diodes manufactured by Microchip Technology. The series offers various voltage ratings within the 2.4V to 200V range. The 1N5270 variant specifically targets the 91V segment. It shares common packaging and material properties with other members of the axial glass-encapsulated family.

Single Zener Diodes Replacement Considerations

Equivalent parts include the MV1N5270DE3TR-1 which offers 1% tolerance and 0.48W rating in a similar DO-35 package. Generic 1N5270 equivalents from other manufacturers may vary in leakage current and tolerance specifications.
