1N5258B-TR

Single Zener Diodes Overview

The Vishay 1N5258B-TR is a silicon planar power Zener diode in the 1N5221 to 1N5267 series, housed in a DO-35 (DO-204AH) through-hole package. It provides a nominal Zener voltage of 36 V with a ±5% tolerance and operates at a test current of 3.4 mA. The device features a maximum power dissipation of 500 mW, a dynamic resistance of 70 Ω, and a reverse leakage current of 0.1 μA at 27 V. It supports junction temperatures up to 175 °C and storage ranges from -65 °C to +175 °C.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for high stability and sharp reverse characteristics
• Features low reverse leakage current levels for efficient regulation
• Includes a 'B' suffix designation indicating standard ±5% Zener voltage tolerance

Single Zener Diodes Applications

• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the ordering code matches the specific suffix required for your application. Confirm the tape and reel specifications align with automated assembly equipment capabilities. Ensure thermal management strategies account for the 500 mW power dissipation limit under expected operating conditions.

Single Zener Diodes Selection Notes

Select this component when a precise 36 V reference is needed in a through-hole configuration. The ±5% tolerance suits general-purpose applications where tight precision is not critical. Consider the DO-35 package dimensions and lead spacing for PCB layout compatibility.

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, offering various options for different circuit requirements while maintaining consistent packaging and performance characteristics across the family.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5258 equivalents. Verify that substitute parts meet the same 36 V nominal voltage, 500 mW power rating, and DO-35 package constraints to ensure functional compatibility.
