1N5245B-TR

Single Zener Diodes Overview

The Vishay 1N5245B-TR is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial leaded package. It provides a nominal Zener voltage of 15 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 test current of 8.5 mA, a maximum reverse leakage current of 0.1 µA at 11 V, and a dynamic impedance of 16 Ω at the test current.

Single Zener Diodes Feature Summary

Single Zener Diodes Procurement Notes

Verify that the ordering code explicitly includes the -TR suffix to confirm taped-and-reeled packaging. Confirm the 'B' suffix designation matches the required ±5% voltage tolerance. Ensure the component meets specific environmental compliance requirements by referencing the material categorization documentation provided by the manufacturer.

Single Zener Diodes Selection Notes

Select this component when a 15 V reference is required in a through-hole assembly. The 500 mW power rating supports moderate current loads. Verify that the 16 Ω dynamic impedance aligns with circuit stability requirements. Consider the operating temperature limits if the application involves high ambient heat or significant self-heating.

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. All devices share similar physical dimensions and electrical testing methodologies defined in document number 85588.

Single Zener Diodes Replacement Considerations

Cross-reference other manufacturers offering 1N5245 equivalents in the DO-35 package. Verify that substitute parts maintain the same 15 V nominal voltage, ±5% tolerance, and 500 mW power dissipation capabilities.

Single Zener Diodes FAQ

What is the dynamic impedance of the 1N5245B-TR?

The typical dynamic impedance (ZZ) is 16 Ω, measured at a test current of 8.5 mA.

How does the suffix '-TR' affect the component?

The '-TR' suffix indicates that the diodes are supplied in a taped-and-reeled format, specifically on a 14-inch reel containing 10,000 units per reel.
