1N5260B-T

Single Zener Diodes Overview

The Vishay 1N5260B-T is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial package. It provides a nominal Zener voltage of 43 V with a standard tolerance of ±5%. The device operates at a test current of 3 mA and dissipates up to 500 mW. Key electrical parameters include a maximum reverse leakage current of 0.1 µA, a dynamic resistance of 93 Ω, and a typical temperature coefficient of 0.095 %/K. It supports junction temperatures up to 175 °C.

Single Zener Diodes Procurement Notes

Verify the specific suffix 'T' against official documentation to confirm tape-and-reel packaging details. Ensure the ordering code matches the required ±5% tolerance designation. Confirm compliance with RoHS standards and material categorization requirements before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a 43 V reference is required within the 1N52xx series. Consider the 93 Ω dynamic resistance and 0.1 µA leakage limits for circuit sensitivity. Evaluate the 500 mW power dissipation capability relative to ambient operating conditions and thermal management constraints.

Single Zener Diodes Part Context

This part belongs to the Vishay 1N5221 to 1N5267 series of small signal Zener diodes. The series covers a wide voltage range from 2.4 V to 75 V. These components are widely used as general-purpose voltage regulators in discrete semiconductor applications requiring reliable performance.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N5260 equivalents or Vishay variants such as 1N5260B-D7. Verify that replacement parts match the 43 V nominal voltage, 500 mW power rating, and DO-35 package dimensions.
