1N5231B-TAP

Single Zener Diodes Overview

The Vishay 1N5231B-TAP 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 of power. Key electrical characteristics include a maximum dynamic resistance of 17 Ω, a reverse leakage current of 5 µA at 2 V, and a typical temperature coefficient of 0.03 %/K.

Single Zener Diodes Procurement Notes

Verify that the ordering code matches the specific suffix required for the desired packaging format. Confirm the component meets RoHS compliance standards as defined by the manufacturer's material categorization documentation. Ensure the selected part number aligns with the intended application requirements before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 5.1 V reference with ±5% tolerance is required in an axial through-hole configuration. Evaluate the 500 mW power dissipation limit against the expected operating conditions. Consider the 17 Ω dynamic resistance for circuit stability requirements.

Single Zener Diodes Part Context

This component 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 'B' suffix indicates the standard ±5% voltage tolerance specification.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same Vishay series include other 1N52xxB variants with different voltage ratings. Cross-manufacturer equivalents must match the 5.1 V nominal voltage, 500 mW power rating, and DO-35 package dimensions.
