1N5226B-TAP

Single Zener Diodes Overview

The Vishay 1N5226B-TAP is a silicon planar power Zener diode in the DO-35 (DO-204AH) glass package. It provides a nominal Zener voltage of 3.3 V with a standard tolerance of ±5%. The device dissipates up to 500 mW at thermal equilibrium and operates within a junction temperature range of -65 °C to +175 °C. Electrical characteristics include a maximum dynamic resistance of 28 Ω, a reverse leakage current of 25 μA at 1 V, and a typical temperature coefficient of -0.07 %/K.

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 indicated by the B suffix. Confirm compliance with material categorization standards as defined in the manufacturer's documentation before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a 3.3 V reference point is required in through-hole designs. The DO-35 package accommodates standard PCB mounting techniques. Evaluate the 500 mW power dissipation limit against expected operating currents. Consider the negative temperature coefficient for applications requiring thermal stability compensation across wide ambient temperature ranges.

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 broad Zener voltage range from 2.4 V to 75 V. The 1N5226B variant specifically targets the lower end of this spectrum, providing precise low-voltage regulation capabilities suitable for general-purpose electronic circuitry.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering equivalent DO-35 packaged Zener diodes rated at 3.3 V and 500 mW. Verify matching electrical parameters including dynamic impedance and leakage current. Ensure physical dimensions and lead spacing are compatible with existing board layouts.

Single Zener Diodes FAQ

What is the polarity marking on the DO-35 package?

A color band denotes the cathode end of the diode.

How does the 'TAP' suffix affect the component function?

The 'TAP' suffix indicates the specific tape and reel packaging configuration (ammopack) and does not alter the electrical or functional properties of the diode.
