Single Zener Diodes Procurement Notes

Verify the specific part number against official manufacturer documentation to ensure compliance with required electrical tolerances and thermal ratings. Confirm that the component meets all necessary environmental standards and RoHS directives prior to integration into final designs.

Single Zener Diodes Selection Notes

Select this component when a precise 43 V regulation point is required in a standard axial package. Consider the 500 mW power dissipation limit and the 93 Ω dynamic impedance characteristics to ensure suitability for the intended circuit load and stability requirements.

Single Zener Diodes Part Context

This component belongs to the 1N5221B-G through 1N5267B-G series manufactured by Comchip Technology. The series covers a broad spectrum of Zener voltages ranging from 2.4 V to 75 V, providing standardized options for various voltage regulation needs within the same physical form factor.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N5260B variants or equivalent 43 V Zener diodes in the DO-35 package, provided they meet identical electrical specifications and thermal performance criteria.

Single Zener Diodes FAQ

What is the maximum reverse leakage current for the 1N5260B-G?

The maximum reverse leakage current is specified as 1 μA at a reverse voltage of 46 V.

How does the thermal resistance affect operation?

The junction-to-ambient thermal resistance is 300 °C/W, which dictates the power derating curve and limits the maximum allowable power dissipation based on ambient temperature.
