1N5254C-TAP

Single Zener Diodes Overview

The Vishay 1N5254C-TAP is a silicon planar power Zener diode with a nominal voltage of 27 V and ±2% tolerance. It operates within a test current range of 1.7 to 20 mA, featuring a maximum dynamic resistance of 41 Ohms at IZT1 and a reverse leakage current of 100 nA at 21 V. The device dissipates up to 500 mW, withstands a junction temperature of 175 °C, and supports an operating temperature range from -65 °C to +175 °C. Packaged in the axial DO-35 (DO-204AH) format, it provides stable voltage regulation for electronic circuits.

Single Zener Diodes Procurement Notes

Verify that the specific suffix 'TAP' corresponds to the taped ammopack configuration containing 10,000 units per reel as defined in the official ordering information. Confirm compliance with material categorization standards by referencing the Vishay documentation link provided in the datasheet. Ensure the selected variant matches the required ±2% tolerance specification for the application.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is critical due to its tight ±2% tolerance compared to standard variants. The DO-35 through-hole package facilitates easy integration into legacy designs or manual assembly processes. Verify that the 500 mW power dissipation rating aligns with the thermal management capabilities of the target circuit environment.

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, utilizing silicon planar technology. The 'C' suffix specifically denotes the tighter ±2% tolerance band, distinguishing it from the standard ±5% 'B' suffix devices within the same product family.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 27 V Zener diodes in the DO-35 package. Ensure equivalent electrical parameters, particularly the 41 Ohm dynamic resistance and 500 mW power rating, are met. Verify that any substitute component maintains the same thermal characteristics and physical dimensions for direct pin-to-pin compatibility.
