1N5227C-TR

Single Zener Diodes Overview

The Vishay 1N5227C-TR is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial leaded package. It provides a nominal Zener voltage of 3.6 V with a tight tolerance of ±2%, as indicated by the 'C' suffix. The device operates at a test current of 20 mA and dissipates up to 500 mW of power. Key electrical characteristics include a maximum reverse leakage current of 15 µA, a dynamic resistance of 24 Ω, and a typical temperature coefficient of -0.065 %/K.

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the 'C' suffix to ensure the required ±2% voltage tolerance. Confirm the '-TR' suffix matches the taped-and-reeled packaging format needed for automated assembly processes. Cross-reference the specific document revision against the manufacturer's official database to validate all electrical parameters before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a precise 3.6 V reference is required in an axial through-hole configuration. The ±2% tolerance distinguishes it from standard ±5% variants. Ensure the application environment remains within the specified operating temperature range and that the 500 mW power dissipation limit is not exceeded under worst-case thermal conditions.

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 voltage range from 2.4 V to 75 V. The 1N5227C-TR specifically utilizes the DO-35 case style, which is designed for high reliability in industrial and commercial environments.

Single Zener Diodes Replacement Considerations

The 1N5227B-TR serves as a direct functional substitute within the same series, offering identical electrical ratings but with a wider ±5% voltage tolerance instead of the tighter ±2% specification found in the C variant.

Single Zener Diodes FAQ

What does the 'C' suffix indicate in the 1N5227C-TR designation?

The 'C' suffix specifies that the Zener voltage tolerance is ±2%, providing higher precision compared to the standard ±5% tolerance offered by the 'B' suffix.

What is the typical temperature coefficient for this diode?

The typical temperature coefficient of the Zener voltage is -0.065 %/K, indicating how the breakdown voltage changes relative to junction temperature variations.
