1N5231B-T

Single Zener Diodes Overview

The Vishay 1N5231B-T is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial leaded package. It provides a nominal Zener voltage of 5.1 V with a standard tolerance of ±5%. The device operates at a test current of 20 mA and dissipates up to 500 mW. Key electrical parameters include a maximum reverse leakage current of 5 µA, a dynamic impedance of 17 Ω, and a typical temperature coefficient of 0.03 %/K.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for robust voltage regulation
• Features a glass DO-35 axial leaded package for through-hole mounting
• Provides stable reference voltages with low dynamic impedance

Single Zener Diodes Applications

• Voltage stabilization circuits
• General-purpose voltage reference applications

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the -TR suffix for tape-and-reel packaging or -TAP for ammopack configuration. Confirm compliance with RoHS standards and material categorization requirements specific to your region before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 5.1 V reference with ±5% tolerance is required. Ensure the application can accommodate the 500 mW power dissipation limit and verify that the thermal resistance characteristics align with the expected ambient operating 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 nominal voltages from 2.4 V to 75 V, offering standardized specifications for general electronic circuit design.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same Vishay family include the 1N5231B-TR and 1N5231B-TAP variants, which share identical electrical characteristics but differ in reel or bulk packaging formats.
