1N5265

Single Zener Diodes Overview

The SMC Diode Solutions 1N5265 is a single silicon planar Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 62V with a standard tolerance of ±5%. The device is rated for a maximum power dissipation of 500 mW at ambient temperature. It utilizes a DO-35 glass axial-lead package, providing an isolated case connection suitable for through-hole mounting. The component operates as a unidirectional rectifier structure optimized for stable voltage clamping and reference functions in electronic circuits.

Single Zener Diodes Procurement Notes

Verify the specific manufacturer marking on the component body to confirm SMC Diode Solutions origin, as the 1N5265 designation is widely used across multiple vendors. Ensure the package matches the DO-35 form factor required by your PCB footprint. Cross-reference the datasheet revision date to confirm compliance with current environmental standards such as RoHS, as manufacturing origins may vary among suppliers offering this generic part number.

Single Zener Diodes Selection Notes

Select this component when a 62V Zener voltage with 5% tolerance is required for low-power regulation tasks. The 500 mW power rating dictates the thermal management strategy; ensure adequate airflow or copper area if operating near maximum limits. Compare the dynamic impedance and test current specifications from the official SMC Diode Solutions datasheet against other manufacturers to ensure compatibility with your specific circuit load requirements.

Single Zener Diodes Part Context

The 1N5265 belongs to the broader family of 1N52xx series Zener diodes, which are standardized axial-lead components widely adopted in industrial and consumer electronics. This series covers a voltage range typically from 2.4V to 200V. The 1N5265 specifically addresses the mid-range voltage segment, serving as a common replacement for legacy designs requiring precise 62V references in compact through-hole assemblies.

Single Zener Diodes Replacement Considerations

Direct replacements include Microchip/Microsemi MQ1N5265BE3 and MQ1N5265UR-1E3TR, which share the 62V specification but differ in package (DO-7 vs DO-35) and tolerance. Verify pinout compatibility and thermal resistance differences before substituting.
