1N4729A-T

Overview

The Vishay General Semiconductor - Diodes Division 1N4729A-T is a silicon planar power Zener diode housed in the DO-41 glass axial leaded package. It provides a nominal Zener voltage of 3.6 V with a standard tolerance of ±10%. The device is rated for a maximum power dissipation of 1.0 W and operates within a temperature range of -65 °C to +175 °C. Designed for stabilizing and clipping circuits, it features double slug construction and oxide passivated die technology.

Feature Summary

• Double slug type construction for enhanced thermal performance
• Oxide passivated die for improved reliability
• Hermetically sealed glass encapsulation

Applications

• Voltage stabilization circuits
• Signal clipping applications
• Reference voltage generation

Procurement Notes

Verify the specific suffix 'T' against official datasheets to confirm packaging details such as tape and reel specifications. Ensure the required voltage tolerance aligns with the standard ±10% rating unless an 'A' suffix variant is specified. Confirm RoHS compliance status through manufacturer documentation prior to integration.

Selection Notes

Select this component for through-hole designs requiring robust voltage regulation in high-power environments. The DO-41 package offers reliable mounting for industrial applications. Consider the ±10% tolerance for general regulation tasks where tighter precision is not critical.

Part Context

This part belongs to the 1N4728A series, which covers a wide voltage range from 3.3 V to 100 V. The series utilizes silicon planar technology and is designed for high-power applications. The 1N4729A specifically targets the 3.6 V regulation segment within this extensive lineup.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4729A equivalents in DO-41 packages. Verify that substitute parts match the 1.0 W power rating and 3.6 V Zener voltage specifications to ensure circuit compatibility.
