1N5260B-TAP

Single Zener Diodes Overview

The Vishay 1N5260B-TAP 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 at 36 V, a typical dynamic resistance of 93 Ω, and a temperature coefficient of 0.095 %/K.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for robust voltage regulation
• Features a glass passivated junction within an axial leaded package
• Includes cathode identification marking on the component body

Single Zener Diodes Applications

• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the ordering code matches the required tolerance suffix. Confirm the package type aligns with the PCB footprint requirements. Ensure the thermal management strategy accommodates the specified power dissipation limits under expected operating conditions.

Single Zener Diodes Selection Notes

Select this component when a precise 43 V reference is needed in a through-hole design. Consider the dynamic resistance and temperature coefficient for stability requirements. Evaluate the forward voltage characteristics if the diode may experience reverse bias breakdown or forward conduction during operation.

Single Zener Diodes Part Context

This part belongs to the 1N5221 to 1N5267 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide range of voltages from 2.4 V to 75 V, offering standardized tolerances for general-purpose electronic applications requiring reliable voltage clamping.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same Vishay series include other 1N52xx variants with different voltage ratings. Cross-manufacturer equivalents must match the 43 V nominal voltage, 500 mW power rating, and DO-35 package dimensions.
