1N5253B-TAP

Single Zener Diodes Overview

The 1N5253B-TAP is a silicon planar power Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 25 V with a standard tolerance of ±5%. The device operates at a test current of 5 mA and dissipates up to 500 mW in the DO-35 (DO-204AH) axial package. Key electrical characteristics include a maximum dynamic resistance of 35 Ω, a reverse leakage current of 0.1 µA at 19 V, and a temperature coefficient of 0.089 %/K.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for high stability and sharp reverse characteristics

Single Zener Diodes Procurement Notes

Verify that the ordering code suffix 'TAP' corresponds to the specific ammopack tape configuration (52 mm tape) as defined in the manufacturer's ordering information. Confirm compliance requirements against the material categorization definitions provided in the official documentation before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a 25 V reference with ±5% tolerance is required. Ensure the application circuit maintains the junction temperature within the specified range and respects the 500 mW power dissipation limit. Verify that the DO-35 package dimensions align with the target PCB layout constraints.

Single Zener Diodes Part Context

This part belongs to the 1N5221 to 1N5267 series of small signal Zener diodes. The series covers a wide Zener voltage range from 2.4 V to 75 V. Other available case styles include MiniMELF, SOT-23, and SOD-123 variants designated by different type prefixes such as TZM or MMBZ.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering equivalent 25 V Zener diodes in the DO-35 package. Ensure replacement parts match the 500 mW power rating and ±5% voltage tolerance specifications.
