1N5229C-TR

Single Zener Diodes Overview

The Vishay 1N5229C-TR is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial package. It provides a nominal Zener voltage of 4.3 V with a tight tolerance of ±2%, tested at a current of 20 mA. The device dissipates up to 500 mW and features a maximum reverse leakage current of 5 µA at 1 V, alongside a dynamic impedance of 22 Ω. It operates within a junction temperature range of -65 °C to +175 °C.

Single Zener Diodes Feature Summary

• High precision voltage regulation achieved through a ±2% tolerance designation
• Robust thermal performance supporting up to 500 mW power dissipation
• Low leakage characteristics ensuring stable operation under reverse bias conditions

Single Zener Diodes Applications

• Voltage stabilization circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the 'C' suffix to confirm the required ±2% tolerance specification. Ensure the procurement request specifies the '-TR' suffix for reel packaging. Confirm compliance with RoHS directives and material categorization requirements before finalizing orders.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is critical due to its narrow manufacturing tolerance. The DO-35 package is suitable for through-hole mounting applications requiring robust mechanical stability. Evaluate the positive temperature coefficient at 4.3 V against circuit thermal environments.

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 'C' suffix specifically denotes tighter manufacturing tolerances compared to standard variants, making it suitable for high-precision analog designs.

Single Zener Diodes Replacement Considerations

Substitute only with other Vishay 1N5229C-TR units or equivalents sharing identical electrical parameters and the DO-35 package. Verify that any alternative maintains the same ±2% tolerance and 500 mW power rating.
