1N5244B-TR

Single Zener Diodes Overview

The Vishay 1N5244B-TR is a silicon planar power Zener diode in the 1N52xxB series, housed in a DO-35 (DO-204AH) axial leaded package. It provides a nominal Zener voltage of 14 V with a standard tolerance of ±5%. The device operates at a test current of 9 mA and dissipates up to 500 mW of power. Key electrical parameters include a maximum reverse leakage current of 100 nA, a dynamic impedance of 15 Ω, and a temperature coefficient of 0.082 %/K. It supports an operating junction temperature range from -65 °C to +175 °C.

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the specific suffixes required for your packaging needs, such as TR for taped reels or TAP for ammopacks. Confirm compliance with RoHS directives and material categorization standards by referencing the official Vishay documentation. Ensure the selected variant matches the exact voltage tolerance and package dimensions required for your assembly process.

Single Zener Diodes Selection Notes

Select this component when a 14 V reference with ±5% tolerance is required in a through-hole configuration. Consider the 15 Ω dynamic impedance and 0.082 %/K temperature coefficient for circuit stability analysis. Verify that the 500 mW power dissipation rating aligns with the thermal management capabilities of the target application environment.

Single Zener Diodes Part Context

This part belongs to the Vishay 1N5221 to 1N5267 family of small signal Zener diodes. These devices are designed for general-purpose voltage regulation tasks. The 1N5244B specifically targets applications requiring a 14 V breakdown voltage. The product line offers various package options including MiniMELF and SOT-23 for different form factor requirements.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5244 equivalents. Verify that substitute parts match the 14 V nominal voltage, 500 mW power rating, and DO-35 package dimensions. Ensure the replacement maintains similar dynamic impedance and leakage current specifications to preserve circuit performance.
