1N5261C-TR

Single Zener Diodes Overview

The Vishay 1N5261C-TR is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial package. It provides a nominal Zener voltage of 47 V with a tight ±2 % tolerance, indicated by the 'C' suffix. The device operates at a test current of 2.7 mA and dissipates up to 500 mW. Key electrical parameters include a maximum reverse leakage current of 0.1 µA at 36 V, a dynamic resistance of 105 Ω, and a typical temperature coefficient of 0.095 %/K.

Single Zener Diodes Feature Summary

• High precision voltage regulation achieved through a ±2 % Zener voltage tolerance
• Robust thermal performance supporting operation up to a junction temperature of 175 °C
• Low reverse leakage current for efficient standby or high-impedance circuit applications

Single Zener Diodes Applications

• Voltage stabilization
• Reference voltage generation
• Overvoltage protection circuits

Single Zener Diodes Procurement Notes

Verify that the ordering code explicitly includes the 'C' suffix to ensure procurement of the ±2 % tolerance variant rather than the standard ±5 % version. Confirm the '-TR' designation matches the required reel packaging specifications for automated assembly processes.

Single Zener Diodes Selection Notes

Select this component when precise voltage clamping is critical and tighter tolerances are required compared to standard B-series devices. Ensure the operating current remains near the specified 2.7 mA test point to maintain accuracy within the guaranteed limits.

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 nominal voltages from 2.4 V to 75 V, utilizing a consistent silicon planar technology housed in the standard DO-35 axial leaded package.

Single Zener Diodes Replacement Considerations

The 1N5261B-TR serves as a direct functional substitute within the same series, offering identical electrical characteristics but with a wider ±5 % Zener voltage tolerance.
