1N5239B-TAP

Single Zener Diodes Overview

The Vishay General Semiconductor - Diodes Division 1N5239B-TAP is a silicon planar power Zener diode housed in the DO-35 (DO-204AH) axial lead package. It provides a nominal Zener voltage of 9.1 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 impedance of 10 Ω, a reverse leakage current of 3 µA at 7 V, and a typical temperature coefficient of 0.068 %/K.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for robust voltage regulation

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the TAP suffix to confirm the specific ammopack packaging format containing 10,000 units per reel. Ensure the component meets the required ±5% voltage tolerance designation. Confirm compliance with RoHS standards and material categorization requirements before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 9.1 V reference is needed in a through-hole axial configuration. Consider the 500 mW power dissipation limit and the 175 °C junction temperature rating during thermal design. Verify that the 10 Ω dynamic impedance aligns with circuit stability requirements.

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. The 1N5239B variant specifically targets applications requiring a 9.1 V breakdown voltage within the standard tolerance band.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5239B equivalents. Verify that replacement parts match the DO-35 package dimensions, 500 mW power rating, and 9.1 V nominal voltage specifications.
