1N4729A-TP

Single Zener Diodes Overview

The MCC 1N4729A-TP is a hermetically sealed silicon planar Zener diode in a DO-41G glass package. It provides a nominal Zener voltage of 3.6 V with a 5% tolerance at a test current of 69 mA. The device dissipates 1.0 W at 50°C, featuring a maximum reverse leakage current of 100 µA and a dynamic impedance of 10 Ω. Operating temperatures range from -65°C to +200°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass package for environmental protection
• Silicon planar construction for stable regulation
• High thermal resistance rating for power dissipation

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the specific 'A' suffix indicates the required 5% voltage tolerance rather than standard 10%. Confirm RoHS compliance status via official datasheets or authorized distributors. Ensure sourcing channels are authorized to prevent counterfeit components. Check for end-of-life notices as availability may be restricted.

Single Zener Diodes Selection Notes

Select this component when a precise 3.6 V reference is needed with tight tolerance. The DO-41G through-hole package suits standard PCB layouts. Verify that the 1.0 W power rating meets circuit requirements without excessive derating. Consider the low dynamic impedance for improved regulation stability under varying load conditions.

Single Zener Diodes Part Context

This part belongs to the 1N4728A through 1N4761 series of 1.0 Watt Zener diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 3.3 V to 75 V. The 'A' suffix specifically denotes a tighter 5% voltage tolerance compared to the standard 10% tolerance found in non-suffixed variants.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 1N4729A specifications. Ensure replacement parts match the DO-41G package dimensions and 5% tolerance requirement. Verify equivalent thermal resistance and maximum operating temperature ratings.
