1N5258/TR

Single Zener Diodes Overview

The Microchip Technology 1N5258/TR is a unidirectional silicon Zener diode rated at 36 V nominal voltage with a ±5% tolerance. It operates in the DO-204AH (DO-35) glass axial-lead package and dissipates up to 500 mW of power. The device supports junction temperatures up to 175 °C and features a reverse leakage current of 100 nA.

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against project requirements, as variants such as 1N5258-1E3 exist with different compliance statuses. Confirm that the selected component matches the required tolerance level and package type before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a precise 36 V regulation point is needed within a compact axial-lead form factor. Ensure the circuit design accommodates the 500 mW power dissipation limit and verify thermal management strategies for operation near maximum temperature ratings.

Single Zener Diodes Part Context

This part belongs to the widely used 1N5221 through 1N5281 series of 0.5 W Zener regulators. The series offers a broad selection of voltages from 2.4 V to 200 V, allowing designers to standardize on a single package style across various voltage requirements.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N5258B variant which shares the same electrical characteristics but may differ in packaging or compliance status. Cross-reference datasheets to confirm pinout compatibility and thermal performance before substitution.
