1N5246C-TR

Single Zener Diodes Overview

The Vishay 1N5246C-TR is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial leaded package. It provides a nominal Zener voltage of 16 V with a tight tolerance of ±2%, indicated by the 'C' suffix. The device dissipates up to 500 mW at thermal equilibrium and operates within a junction temperature range of -65 °C to +175 °C. Key electrical parameters include a test current of 7.8 mA, a maximum reverse leakage current of 0.1 µA at 12 V, and a dynamic impedance of 17 Ω at the test current.

Single Zener Diodes Feature Summary

• High precision voltage regulation achieved through a ±2% Zener voltage tolerance
• Robust thermal performance supporting operation up to a 175 °C junction temperature
• Low leakage current characteristics suitable for sensitive circuit applications

Single Zener Diodes Applications

• Voltage stabilization circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the ordering code explicitly includes the 'C' suffix to ensure the component meets the required ±2% voltage tolerance specification. Confirm the '-TR' suffix corresponds to the taped and reeled packaging format intended for automated assembly processes. Cross-reference the document number 85588 to access the latest technical specifications and compliance data.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is critical, as the standard 'B' suffix variant only offers ±5% tolerance. Ensure the application requires the specific 16 V breakdown voltage provided by the 1N5246 series. Verify that the DO-35 through-hole package aligns with the board layout requirements and that the 500 mW power dissipation rating is sufficient for the operating conditions.

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. The 1N5246 designation specifically identifies the 16 V nominal voltage point within this extensive lineup of silicon planar devices designed for general-purpose voltage regulation tasks.

Single Zener Diodes Replacement Considerations

Direct replacements include other manufacturers' 1N5246C variants or Vishay's own MMSZ5246C-E3-18 in SOD-123 and MMBZ5246C-E3-08 in SOT-23 packages. These alternatives offer identical electrical characteristics but require different footprint considerations due to surface-mount packaging.
