1N5239C-TR

Single Zener Diodes Overview

The Vishay 1N5239C-TR is a silicon planar power Zener diode with a nominal voltage of 9.1 V and a tight tolerance of ±2%. It operates in the DO-35 (DO-204AH) axial lead package, dissipating up to 500 mW at thermal equilibrium. The device features a maximum reverse leakage current of 3 µA at 7 V and a dynamic resistance of 10 Ω at a test current of 20 mA. It supports junction temperatures up to 175 °C and storage ranges from -65 °C to +175 °C.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a ±2% tolerance for high accuracy applications
• Utilizes silicon planar technology for robust performance and reliability
• Offers low dynamic resistance to maintain stable output under varying load conditions

Single Zener Diodes Applications

• Voltage stabilization circuits
• Reference voltage generation
• Overvoltage protection systems

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the specific suffix indicating the ±2% tolerance grade. Confirm the reel packaging format matches production requirements. Ensure compliance with RoHS directives if applicable to your manufacturing standards. Cross-reference the document revision date to ensure you are using the latest electrical characteristics.

Single Zener Diodes Selection Notes

Select this component when a tighter voltage tolerance than standard grades is required. The DO-35 package is suitable for through-hole mounting on printed circuit boards. Consider the thermal resistance and ambient temperature limits to ensure the 500 mW power dissipation rating is not exceeded during operation.

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 range of nominal voltages from 2.4 V to 75 V. The 'C' suffix specifically denotes the tighter ±2% tolerance variant compared to the standard ±5% 'B' grade.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N5239C equivalents or Vishay's TZM5239C MiniMELF version for surface mount needs. Verify that replacement parts match the 9.1 V nominal voltage, 500 mW power rating, and ±2% tolerance specifications.
