1N5262B-TAP

Single Zener Diodes Overview

The Vishay 1N5262B-TAP is a silicon planar power Zener diode with a nominal voltage of 51 V and a tolerance of ±5%. It operates in the DO-35 (DO-204AH) glass axial package. The device provides a maximum power dissipation of 500 mW at 25 °C ambient temperature, with a junction temperature rating up to 175 °C. Electrical characteristics include a test current of 2.5 mA, a reverse leakage current of 0.1 µA at 39 V, and a dynamic resistance of 125 Ω.

Single Zener Diodes Feature Summary

• Silicon planar construction for reliable voltage regulation
• Standard ±5% Zener voltage tolerance designated by the 'B' suffix
• Glass axial DO-35 package suitable for through-hole mounting

Single Zener Diodes Applications

• Voltage stabilization circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the -TAP suffix to confirm the specific ammopack tape configuration. Ensure the required Zener voltage matches the 51 V specification and that the ±5% tolerance aligns with circuit requirements. Confirm compliance with RoHS3 standards and check material categorization documentation if restricted substance limits apply to the project.

Single Zener Diodes Selection Notes

Select this component when a standard 51 V reference is needed in an axial glass package. The 500 mW power rating supports moderate current applications. Verify that the thermal resistance of 300 K/W and lead length constraints fit the PCB layout. Consider the 125 Ω dynamic impedance for noise-sensitive designs requiring stable regulation under varying load conditions.

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. The 1N5262B variant specifically targets the 51 V segment within this lineup, offering consistent performance across the family's standardized DO-35 package format.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers producing 1N5262B equivalents in the DO-35 package. Verify that substitute parts meet the same 51 V nominal voltage, ±5% tolerance, and 500 mW power dissipation ratings. Ensure the replacement maintains compatibility with the axial lead spacing and glass encapsulation style.
